Elektromagnetische Simulation
Die magnetische und elektrische Feldmodellierungssoftware

Über EMS

EMS ist eine Software zur Simulation elektromagnetischer Felder, die Felder (elektrisch/magnetisch/Fluss/Potential/Wirbelströme), Schaltungsparameter (Induktivität/Kapazität/Widerstand/Impedanz/Flussverknüpfung), mechanische Parameter (Kraft/Drehmoment) und Verluste (Wirbel//Kern/Hysterese/Ohm)  berechnet. EMS ist ein Gold-zertifiziertes Add-In für SOLIDWORKS® und ein Add-In für Autodesk® Inventor®, mit dem Sie die kompliziertesten elektrischen Maschinen, Motoren, Generatoren, Sensoren, Transformatoren, Hochspannungsgeräte, Hochleistungsmaschinen und elektrischen Schalter, Ventile, Aktuatoren, Leiterplatten, Schwebemaschinen, Lautsprecher, Permanentmagnetmaschinen, ZfP-Geräte, Wechselrichter, Wandler, Sammelschienen, Induktivitäten, Durchführungen oder biomedizinische Geräte  simulieren können.

Besonderheiten und Funktionen

Vollständige 3D-Simulation elektromagnetischer Felder: Mit EMS können Sie sowohl elektrische als auch magnetische Simulationen unter Verwendung Ihrer vollständigen 3D-Geometrie durchführen, um eine 100% Genauigkeit und Integrität Ihrer Entwürfe sicherzustellen. EMS schafft auch 2D-Planar- und Achsensymmetriesimulationen für Konstruktionen, bei denen eine solche Vereinfachung die Lösungszeit erheblich verkürzt, ohne Kompromisse bei der Genauigkeit einzugehen.

Vollständige Integration in die CAD-Geometrie: Die nahtlose Integration von EMS in die beiden wichtigsten CAD-Plattformen - SOLIDWORKS und Autodesk® Inventor® - ermöglicht es Ihnen, die kompliziertesten elektromagnetischen Konstruktionen zu simulieren. Sie müssen das Rad nicht "neu erfinden", sondern nur ein CAD-Modell vom mechanischen Zeichner erwerben und Ihre elektrische oder magnetische Simulation sofort ohne Änderungen starten.

Parametrische Simulation: Für das perfekte Design ermöglicht EMS zahlreiche Analysen. Jede CAD-Dimension oder Simulationsvariable kann als Parameter festgelegt werden, um die Auswirkungen ihrer Änderungen auf Ihr Design zu untersuchen. Dies dient als erster Schritt zur Optimierung Ihrer Designs.

Multiphysik-Funktionen: EMS ist eine echte Multi-Physik-Software, mit der Sie Ihr magnetisches und elektrisches Design in einer problemlosen integrierten Umgebung mit Schaltkreis-, Bewegungs-, Wärme- und Strukturanalysen an demselben Modell koppeln können, ohne Daten importieren oder exportieren zu müssen. Diese integrierte Multi-Physik-Umgebung bringt dem Benutzer Effizienz, Genauigkeit und Produktivität.

Benutzerfreundliche Oberfläche und eingebettete Lernmaterialien: Einfach zu bedienendes Programm mit einer sehr kurzen Lernkurve. Befolgen Sie die gleiche Philosophie Ihrer CAD-Software. Die Demo-Viewer-Funktion in der Software bietet Ihnen Zugriff auf zahlreiche Schulungsmaterialien zum schnellen Lernen und zur Einführung von EMS.

MAGNETIC FIELD ENHANCEMENT OF THE QUAD CONFINEMENT THRUSTER (QCT): DESIGN AND EARLY DEVELOPMENT OF THE QCT PHOENIX

  • Ian Hunter
    Ian Hunter
    PhD

    A Lorentz force linear motion actuator was built to deliberately exhibit a highly nonlinear current for force relation even when the coil was completely immersed in the magnetic field. Magnets were arranged radially around the coil but only half the permissible number were included in order to generate a more complex actuator configuration to test the ability of the EMS electromagnetic finite element analysis software to handle more challenging magnetic path geometries. A detailed set of experiments were carried out on the actual actuator and a similar set of analyses were undertaken using the EMS magnetostatic electromagnetic finite element analysis software. EMS correctly accounted for the gross nonlinearities in the current to force measurements.

    I used EMS to simulate primary and secondary current distributions in our electrochemical cells using the Electric Conduction module.Using this tool, we succeeded in optimizing the setup of the electrochemical cells by studying various material of the electrodes and the bath parameters such as the acid concentration and temperature.A trial-and-error procedure would have taken us years to achieve the optimal design achieved using EMS. It was a well worth it investment.

    Inovio Pharmaceuticals (formerly Genetronics), specializes in developing technology and hardware that has the potential to allow physicians to more efficiently and cost-effectively deliver life-saving drugs or beneficial genes to patients with catastrophic illnesses, including cancer. The company is the technology leader in electroporation therapy (EPT), the application of very brief, carefully controlled, pulsed electric fields, to human cells. This process causes pores to open in the cell membrane and allows pharmaceuticals or genes, injected in the area prior to the application of the electric pulse, to gain access to the cell's interior. The cell pores close up a short time later, trapping the chemotherapeutic agents inside the cancer cell, so they can destroy the cell



    EMS and SolidWorks play a vital role in evaluating the electrical fields used with Inovio's electroporation devices, helping to determine and optimize the electrical field strength throughout the volume of space around the electrodes



    EMS and SolidWorks have significantly sped up Inovio product development. "The time savings are so dramatic they are, in a sense, unquantifiable," says Andre. "Using EMS, we can change an electrode geometry and analyze an electrical field within a half hour. If we had to do these three dimensional calculations for the more complicated electrode geometries by hand, it would take days."

    For about 2 years we are using EMS, mostly for electrical field calculation in high voltage equipment. Also we are a very young company; we personally have a long time experience using finite element software. To get familiar with EMS, I have had a web seminar. Some hours on some days were enough to start up. The support during the “learning time” by the EMS Team was very good. Now I’m an experienced user, phone calls with the service team become more and more seldom.

    What’s the extract?

    * EMS is well structured; the use is intuitive and logical.

    * It works together with Solid Works without problems.

    * The output (reports and pictures) is clear and in very good quality.

    * Very good support.

    Conclusion: Highly recommended

    In our bachelor thesis, a patented “bifilar” coil (BC) type permanent magnet generator (PMG) is constructed for scientific research. The features, working principle and elements of the BCPMG are analyzed.

    The BCPMG is developed from the iron-cored “bifilar” coil topology based on Aleksas Pašilis's and Eleonora Guseinovien's patent (Lithuania) in an attempt to overcome the problems with current rotary type Generators, which have so far been dominant on the market.

    One of the problems is Armature Reactance, which is usually bigger than Resistance.

    The circumstance creates difficulties for designers and operators of the Generator.

    "...That is why patented technology is offered to partially remove or absolutely neglect the reactance of the machine. We used The Simulation Software EMS:

    To get to the flow direction of the Magnetic Flux Densities through the system, which the same is as expected to be.

    To test to a real machine. We found the opportunity of the motion simulation, but there wasn't much time for that investigation.

    We have made only a 1/5 sector of the generator to keep the resources at minimum.

    We used also a Finite Element Magnetic Model (FEMM) to visualize the effects of the system.

    To visualize the effects of the 3 phase current to the flow of flux and densities on the system."

    We have heard about the EMWorks software as a result of searching for Finite Element Modelling (FEM) software which would be adequate for our purposes. After the review of various offers we stated that EMS has all features we need. The great advantage of this package is that it is based on SolidWorks.

    It is a powerful simulation tool that I would recommend to anyone who is doing projects on induction heating.

    Over the past year, I’ve had the opportunity to use EMWorks to aid in my study of magnetic coils on our apparatus. With this tool, we can model many types of coil designs, such as using thin magnet wire, and water cooling it, or instead going with hollow-core type of wiring (with finite diameters and realistic spiraling modeled in SW) and running cool water through that. We can then see our magnetic field profiles all around the coils, and of course in the center of our Helmholtz configuration, where we would like to ensure very flat magnetic fields. In a complex environment such as a cold-atom experiment, I want to ensure that the vacuum chamber geometry itself would not impede our ability to ramp up and down the current on the magnetic coils, due to eddy currents. By tuning the materials, and in real-time designing components the way they would be engineered, we will be able to fine-tune our apparatus to our needs and constraints. In the future, we will continue to evaluate the eddy currents present in our system as we try different parameters for our magnetic field control (see image).

    One great aspect to continue expanding on would be the video tutorials highlighting the many ways to get students started on using EMWorks for their applications. As a beginner, setting up the basic parameters like the “air geometry” was made simpler by watching someone show those steps specifically through SolidWorks.

Eine Transformator-Berechnungssoftware

EMS dient sich als Transformator-Design-Software. EMS kann verwendet werden, um kritische Transformator-Entwurfsparameter virtuell zu untersuchen, einschließlich:

Energiespeicher

Ein Transformator darf keine Energie speichern, sondern sofort von Eingang zu Ausgang übertragen. Leider speichern Transformatoren in der Realität unerwünschte Energie. EMS berechnet die Streuinduktivität, die die gespeicherte Energie zwischen Wicklungsbereichen darstellt, die von nichtmagnetischen Medien besetzt sind. In ähnlicher Weise berechnet EMS die gegenseitige Induktivität, die die Menge an unerwünschter gespeicherter Energie im Magnetkern und kleinen Luftspalten angibt.

Verluste und Wärmemanagement

EMS kann den maximalen Temperaturanstieg des „Hot Spots“ an der Kernoberfläche innerhalb des Wicklungszentrums berechnen. Diese Berechnung ist hilfreich bei der Bestimmung der kleinsten Kerngröße, die den erforderlichen Wirkungsgrad der Stromversorgung erfüllt, ohne die maximale „Hot Spot“ -Temperatur zu überschreiten. Um diesen Temperaturanstieg zu berechnen, berücksichtigt EMS alle Transformatorverluste, einschließlich Wirbelverlust, Hystereseverlust, Kernverlust, Wicklungsverlust und Wärmeverlust sowie die umgebenden Flüssigkeitstemperatur- und Konvektionseigenschaften.

Kernauswahl

EMS berechnet die magnetische Flussdichte und die Sättigungsniveaus im Kern, die bei der Auswahl des richtigen Kernmaterials, der richtigen Form und Größe für jede Frequenz und gewünschte Leistungsabgabe hilfreich sein können. Der Konstrukteur des Transformators zielt letztendlich darauf ab, eine Form zu wählen, die einfach herzustellen ist, eine möglichst kleine Kerngröße und das kostengünstigste Kernmaterial, wobei die erforderliche Leistung eingehalten wird, ohne den Kern zu sättigen.

Unterbrechungs- und Kurzschlusstests

Leerlauf- und Kurzschlusstests eines Transformators sind kritisch, aber kostspielig und zeitaufwändig. Mit EMS kann der Designer diese Tests virtuell genau und effizient ausführen.

Isolationskoordination

EMS berechnet den dielektrischen Durchschlag, der für die Auswahl der richtigen Durchführungen, Überspannungsableiter und anderer isolierender Infrastrukturen von entscheidender Bedeutung ist. Diese Art der Berechnung hilft dem Konstrukteur, die verschiedenen Isolationskoordinierungsstandards zu erfüllen.

Kurzschlusskräfte

EMS berechnet die Magnetkraft, die sowohl auf die Wicklungen als auch auf das Kernmaterial wirkt, sowie die Spannung und strukturelle Verschiebung aufgrund dieser Kräfte. Diese Art von Berechnungen ist hilfreich, um die strukturelle Integrität des Transformators zu gewährleisten.

Eine Motorberechnungssoftware 

EMS dient sich als Motorkonstruktionssoftware. Sie kann verwendet werden, um kritische Konstruktionsparameter für Elektromotoren virtuell zu untersuchen, einschließlich:

Parameterschätzung

Wicklungsinduktivität und -widerstand spielen eine wichtige Rolle bei der Steuerung und Zustandsschätzung von Elektromotoren. Das Beispiel hierfür wäre eine Phasenstromregelung in einem SRM-Motor oder eine Rotorpositionsschätzung in einem sensorlosen BLDC. EMS kann diese Parameterwerte für einen gewünschten Satz von Frequenz- und Strombedingungen bestimmen.

3D-Modellierungsprobleme

EMS ist eine vollständige 3D-Modellierungsplattform. Dies ermöglicht die Simulation einiger wichtiger Topologien und Effekte, die ansonsten nicht analysiert werden können:
- Das Schwenken von Schlitzen oder Rotorpolen ist eine übliche Technik zur Reduzierung der Rastkraft. Die Ergebnisse können nur geschätzt werden, wenn die Wechselwirkung zwischen Stator und Rotor in allen drei Dimensionen erfasst wird.
- Fortgeschrittene Maschinentopologien wie Axialfluss- und Querflussmaschinen arbeiten von Natur aus mit 3D-Flussverteilung und sollten als solche behandelt werden.
-Endwicklungen haben einen erheblichen Einfluss auf den Wicklungswiderstand sowie dessen Streuinduktivität.

Drehmoment

EMS kann transiente und stationäre Drehmomentprofile für verschiedene elektrische Maschinentopologien wie Permanentmagnet-Wechselstrommaschine, BLDC, geschaltete Reluktanz, Induktion usw. berechnen. Drehmomentergebnisse für verschiedene Rotordrehzahlen und Wicklungsströme bestimmen die optimalen Betriebsbedingungen. Darüber hinaus hilft EMS, das Rastmoment zu minimieren, indem seine Größe für verschiedene Luftspaltlängen oder Teilschlitzabstände verglichen wird.

Kernmaterial

Eine erfolgreiche Maschinenkonstruktion hängt von der genauen Darstellung des nichtlinearen Phänomens im Kernmaterial ab, wie z. B. Flusssättigung, Wirbelstrom und Hystereseverluste. EMS wird mit einer Bibliothek vordefinierter fester und laminierter Kernmaterialien geliefert. Designer können verschiedene Materialien hinsichtlich Sättigung, Kernverlusten und Gesamteffizienz leicht vergleichen. Kern- und Wicklungsverlustergebnisse können mit dem thermischen Löser von EMS gekoppelt werden und bestimmen den Temperaturanstieg und die Kühlanforderungen.

Form und Größe

Der Radius, die Länge und die Anzahl der Pole der Maschine bestimmen maßgeblich das Drehmoment und die Nennleistung. Feinere geometrische Merkmale des Magnetkreises haben jedoch einen tiefgreifenden Einfluss auf die Maschinenleistung. Beispielsweise beeinflusst die Form der Käfigstangen in einem Induktionsmotor, wie sich das Drehmoment mit dem Rotorschlupf ändert. Alle diese Parameter können innerhalb von EMS leicht variiert werden, um ihre Auswirkung auf die Leistung des Motors zu bewerten.

Parasitäre RLC-Extraktion

EMS kann als parasitärer RLC-Extraktor verwendet werden. Das heißt, es berechnet genau den Widerstand, die Induktivität und die Kapazität für jede beliebige elektrische und elektronische 3D-Struktur. Diese Berechnungen berücksichtigen den Proximity-Effekt, den Skin-Effekt, den dielektrischen und ohmschen Verlust sowie die Frequenzabhängigkeit. Mit anderen Worten werden sowohl DC- als auch AC-parasitäre RLC berechnet. Diese parasitären Werte sind maßgeblich an der Modellierung verschiedener elektrischer und elektronischer Geräte und Schaltkreise beteiligt, darunter:

Hochgeschwindigkeitselektronik

RLC-Modelle für elektronische Hochgeschwindigkeitsgeräte wie ICs, Leiterplatten, Gehäuse und passive On-Chip-Komponenten sind für die Untersuchung von Übersprechen und Verzerrung, Verbindungsverzögerungen und Klingeln sowie Erdungsprellen von entscheidender Bedeutung.

Stromrichter

RLC-Modelle sind nützlich bei der Simulation leistungselektronischer Geräte wie Sammelschienen, Kabel, Wechselrichter und Wandler, die üblicherweise in Stromverteilungsanwendungen verwendet werden, sowie Hybrid- und Elektrofahrzeuge.

Touchscreen-Modellierung

Die Modellierung von Touchscreens in heutigen Smartphones und Computern hängt stark von der genauen Berechnung der Kapazität der Bildschirmkabel ab.

NDT-Simulationssoftware

Elektromagnetische Felder und Wellen werden häufig in zerstörungsfreien Prüftechnologien eingesetzt. Da EMS den Magnetfluss und den Wirbelstrom genau berechnet, deckt es eine Vielzahl von elektromagnetischen ZfP-Techniken ab, darunter: Wirbelstromprüfung (ECT), Magnetflussleckage (MFL), Fernfeldprüfung (RFT), Magnetpulverprüfung (MPI) , Impulse Wirbelstrom (PEC) und die Wechselstromfeldmessung (ACFM). Das NDT-Screening beinhaltet üblicherweise die Bewegung der NDT-Sonden. EMS eignet sich gut zur Modellierung dieser Art von Bewegung, da EMS mit Solidworks Motion gekoppelt ist.

Vollständige Integration von Solidworks und Autodesk Inventor

Durch die nahtlose Integration von EMS in die drei wichtigsten CAD-Plattformen können Sie die kompliziertesten elektrischen Maschinen, Motoren, Generatoren, Sensoren, Transformatoren, Hochspannungsgeräte, Hochleistungsmaschinen, elektrischen Schalter, Ventile, Aktuatoren, Leiterplatten, Schwebemaschinen und Lautsprecher simulieren. Permanentmagnetmaschine, ZfP-Ausrüstung, Wechselrichter, Wandler, Sammelschiene, Induktor, Buchsen oder biomedizinische Ausrüstung. Sie müssen das Rad nicht "neu erfinden", sondern nur ein CAD-Modell vom Personal für mechanisches Zeichnen erwerben und Ihren Magneten oder Ihre Magnetsimulation sofort ohne Änderungen starten. Wenn Sie das erworbene CAD-Modell ändern möchten, müssen Sie nicht zum Zeichnungspersonal zurückkehren, da kommerzielle CAD-Pakete wie Solidworks parametrisch und hierarchisch sind. Ändern Sie es selbst "on the fly". Wenn die Zeichnungsabteilung oder der Kollege ein anderes CAD-Paket verwendet, können sie es höchstwahrscheinlich in Parasolid, ACIS, IGES, STEP, STL, CATIA oder ProE-Kernel für Sie speichern. Anschließend importieren Sie es in SOLIDWORKS®, Autodesk® Inventor® oder Ansys SpaceClaim und setzen Ihr elektromagnetisches Design fort.

Multi-Physik-Fähigkeiten

EMS ist ein echtes Multi-Physik-Software- und Simulationspaket. Sie können Ihr magnetisches, magnetisches und elektrisches Design mit thermischen, strukturellen und Bewegungsanalysen am selben Modell und Netz in einer problemlosen integrierten Umgebung koppeln, ohne Daten importieren oder exportieren zu müssen. Diese integrierte Multi-Physik-Umgebung bedeutet: kein Durcheinander, kein Herumspringen, kein Mischmasch, kein Chaos, keine Verwirrung und kein Durcheinander. Es bedeutet auch: Effizienz, Genauigkeit und Produktivität.

Elektrothermische Analyse

Ihr Design beinhaltet elektrothermische Aspekte? Einfach und freihändig! Überprüfen Sie einfach den stationären oder vorübergehenden Zustand "Paar zu thermisch" in den Studieneigenschaften. EMS berechnet automatisch die Joule-, Wirbel- und Kernverluste und führt sie dem thermischen Löser zu. Sie können leicht nicht elektromagnetische Wärmebelastungen hinzufügen, indem Sie Volumenwärme, Wärmefluss oder einfach eine feste Temperatur anwenden. Unter Berücksichtigung der Umgebungsbedingungen wie Konvektion und Strahlung berechnet EMS Thermal Steady State oder Transient die Temperatur, den Temperaturgradienten und den Wärmefluss und speichert sie im Ordner "Thermal Results".

Elektrostrukturanalyse

Aus dem gleichen Grund ist auch die elektromechanische Kopplung einfach und freihändig. Die Option "Mit Struktur koppeln" ruft den EMS-Strukturlöser auf, nachdem die lokale Kraftverteilung in relevanten Teilen zusätzlich zu den mechanischen Belastungen und Einschränkungen übertragen wurde, und berechnet dann die Verschiebungen. Die Beanspruchung und Dehnung werden anschließend abgeleitet und ebenfalls dem Ordner "Strukturelle Ergebnisse" hinzugefügt. Wenn die allgemeinere elektrothermomechanische Kopplung gewünscht wird, überträgt EMS sowohl die thermischen als auch die strukturellen Belastungen auf die thermischen und strukturellen Löser. Der thermische Löser wiederum speist die thermischen Lasten dem strukturellen Löser zu, der die endgültigen Verschiebungen berechnet, die sowohl die elektromagnetischen als auch die thermischen Lasten widerspiegeln, wobei die magnetischen, elektrischen, thermischen und strukturellen Umgebungen berücksichtigt werden.

Solidworks Motion Integration

Elektrische Maschinen und Antriebe umfassen normalerweise bewegliche Teile und Komponenten. Im Allgemeinen ist die resultierende Bewegung einfach rotierend wie Motoren oder translatorisch wie Linearantriebe. Trotzdem können einige Anwendungen wie MagLev- und Eddy-Strombremsung alle Bewegungen um sechs Freiheitsgrade provozieren. In diesem Fall kann nur EMS mit solch komplizierten Maschinen und Geräten umgehen. Warum? Weil EMS mit dem vielseitigsten und leistungsstärksten mechanischen Bewegungspaket, Solidworks Motion®, gekoppelt ist. Weitere Informationen zu diesem robusten Paket finden Sie unter: https://www.solidworks.com/sw/products/simulation/motion-analysis.htm Die Kopplung an SolidWorks Motion® ist wieder problemlos. Weisen Sie EMS nach dem Erstellen einer SolidWorks Motion®-Studie einfach an, sie zu koppeln. Das ist es und das ist alles.

Grabcad, 3dcontencentral, Traceparts

In den letzten Jahren ist eine wachsende Anzahl kostenloser 3D-CAD-Modelle - Millionen - in CAD-Depots wie grabcad.com, www.3dcontentcentral.com und www.traceparts.com verfügbar geworden. Folglich können Sie einfach ein CAD-Modell aus den Verwahrstellen holen, notwendige Änderungen vornehmen und sofort mit der Finite-Elemente-Analyse beginnen.

What is Electrostatic Analysis? And what is used for?

Electrostatic is the branch of science that deals with the phenomena arising from stationary and/or slow-moving electric charges. Electrostatic approximation rests on the assumption that the electric field is irrotational, i.e. the curl of the electric field is null. From Faraday's law, this assumption implies the absence or near-absence of time-varying magnetic fields, i.e. the derivative of the magnetic field with respect to time is also null. In other words, electrostatics does not require the absence of magnetic fields or electric currents. Rather, if magnetic fields or electric currents do exist, they must not change with time, or in the worst-case, they must change with time only very slowly. In some problems, both electrostatics and magnetostatics may be required for accurate predictions, but the coupling between the two can still be ignored.

The EMS/Electrostatic module is primarily used for computing electric potential and electric field due to charges and voltages in insulators and conductors.It has many practical applications, including:

• High Voltage Components

What is Electric Conduction Analysis? And what is used for?

Electric Conduction is, in essence, based on the electrostatic approximation. Unlike the Electrostatic analysis which deals with insulators and electric conductors, the Electric Conduction deals with only conducting media which can sustain a current flow.

The EMS/ Electric Conduction module is primarily used for computing current flow in conductors due voltage differences. . It has many practical applications, including:

What is Magnetostatic Analysis? And what is used for?

Magnetostatics is the study of static magnetic fields. In electrostatics, the charges are stationary, whereas here, the currents are steady or dc(direct current). As it turns out magnetostatics is a good approximation even when the currents are not static as long as the currents do not alternate rapidly. Furthermore, Maxwell's displacement current that couples the electric and magnetic fields is assumed to be null.

In EMS/ Magnetostatic analysis, the Gauss's law for magnetism, i.e. divergence of magnetic flux density is null, and Ampère's law, i.e. the curl of the magnetic field is equal to the static electric current density, are invoked to compute the magnetic field and its related quantities due to electric currents and permanent magnets. It has many practical applications, including:

• Motors and generators
• Linear and rotational actuators
• Relays
• MEMS
• Magnetic recording heads

What is AC Magnetic Analysis? And what is used for?

AC, or alternating current, Magnetic, is the study of magnetic fields due to alternating, or time harmonic, currents. Similar to Magnetostatic, Maxwell's displacement current that couples the electric and magnetic fields is assumed to be null.

In EMS/AC Magnetic analysis, the Gauss's law for magnetism, i.e. divergence of magnetic flux density is null, and Faraday's law,, i.e. the induced electromotive force (emf) in any closed circuit is equal to the time rate of change of the magnetic flux through the circuit, are invoked to compute the magnetic field and its related quantities due to alternating electric currents and voltages. It has many practical applications, including:

• AC Motors and generators
• Sensors
• Coils and transformers
• Inverters
• Converters
• Bus bars
• Inductors

What is Transient Magnetic Analysis? And what is used for?

Transient Magnetic, is the study of magnetic fields due to time varying currents, typically caused by surges in currents. Similar to Magnetostatic and AC Magnetic, Maxwell's displacement current that couples the electric and magnetic fields is assumed to be null.

In EMS/ Transient Magnetic analysis, the Gauss's law for magnetism, i.e. divergence of magnetic flux density is null, and Faraday's law,, i.e. the induced electromotive force (emf) in any closed circuit is equal to the time rate of change of the magnetic flux through the circuit, are invoked to compute the magnetic field and its related quantities due to permanent magnets and time varying electric currents and voltages.

Can you give me some examples of design issues that EMS/Electrostatic module can address?

The Electrostatic module can help study a large number of devices and address numerous insulating and conducting phenomena. Below is just a partial list:

• Avoid rapid reduction in the resistance of an electrical insulator, that can lead to a spark jumping around or through the insulator, i.e. dielectric breakdown. This phenomenon is common in high voltage and high power applications.
• Avoid the ionization of a fluid surrounding a conductor, i.e. corona effect, in some applications such as power transmission equipments, transformers, capacitors, electric motors and generators.
• Produce corona in some other applications such as the manufacturing of ozone, scrubbing particles from air in applications such as air-conditioning systems, in nitrogen laser, when removing the unwanted electric charges from the surface of aircraft in flight, and in electrostatic copying.
• Assure that a high voltage machine is properly grounded.

Can you give me some examples of design issues that EMS/Magnetostatic module can address?

The Magnetostatic module can help study a large number of devices and address numerous magnetic and electromechanical phenomena. Below is just a partial list:

• Avoid saturation in magnetic devices. Magnetic saturation is a limitation occurring in ferromagnetic cores. Initially, as current is increased the flux increases in proportion to it. At some point, however, further increases in current lead to progressively smaller increases in flux. Eventually, the core can make no further contribution to flux growth and any increase thereafter is limited to that provided by air - perhaps three orders of magnitude smaller.
• Minimize the cogging torque. The cogging torque of electrical motors is the torque due to the interaction between the permanent magnets and the stator slots of a Permanent Magnet (PM) machine. Also termed as detent or 'no-current' torque, it is an undesirable component for the operation of such a motor. It is especially prominent at lower speeds, with the symptom of jerkiness.

• Study the effect of B-H curves or magnetization curves on the performance of magnetic devices and circuits.
• Optimize the torque in motors while maintaining the driving current to a minimum.
• Avoid sparking and thus minimizing brush wear and electric noise in motors, solenoids, actuators, and other electromechanical devices.
• Optimize the force for linear solenoids and the torque for rotary solenoids without overheating the winding.
• Assure the proper Lorentz force in a speaker voice coil.
• Evaluate complex coil structures.

Can you give me some examples of design issues that EMS/AC Magnetic module can address?

• Optimize the Non-Destructive Testing (NDT) and Non-Destructive Evaluation (NDE) sensors to detect deep flaws and cracks.
• Study time varying devices such as magnetic heads, pulsed power transformers, and electromagnetic launchers.
