EMWorks2D Applications

Permanent magnet brushless DC motors (PMBLDC) are used in a wide range of applications thanks to their high-power density and ease of control. In particular, outer runner PMBLDC is utilized in direct drive wind turbines and small electric vehicles such as golf cars and electric bikes to mitigate the need for mechanical transmission or gearboxes. This can improve the efficiency of the whole system which results in a longer battery lifetime

Magnetic levitation is a method by which an object is suspended in the air with no support other than magnetic fields. The fields are used to reverse or counteract the gravitational pull and any other counter accelerations. It is a highly advanced technology and has various uses. The common point in all applications is the lack of contact and thus no wear and friction. This increases efficiency, reduces maintenance costs, and increases the product lifespan.

Eddy current brakes are based on the braking torques (forces) generated by induced Eddy Currents inside an electrical conductor by electromagnetic induction. Stationary electric conductor immerged inside a time-varying magnetic flux and/ or a moving electrical conductor inside a static magnetic flux will lead to the creation of eddy currents in this conductor.

Electric motors are becoming increasingly used in industrial applications. They offer a high efficiency, high power factor and a wide speed range. The spoke type motor is one of the common electric motor types presented in the market today. Spoke type motors use a compact permanent magnets structure, arranged in spokes for a better torque generation [1]. With the adequate material selection, the spoke type motors have the highest torque density architecture among the permanent magnet motor types, provided they are cost-effectively manufactured and especially effectively cooled [1].

In this application, a 2D model of high-power busbars is analyzed using EMWorks2D inside SOLIDWORKS. Transient electromagnetic simulations are performed to compute the different busbars parameters including magnetic field, eddy currents, proximity effects, electromagnetic losses, etc.

Battery and electric motor are the main keys of any zero-gas emissions vehicle. Hence, engineers, researchers and labs are working to design and develop more reliable products that could meet any user requirements

Permanent Magnet Synchronous machines (PMSMs) are widely used in traction applications and electric vehicles, where steady-state operation, high efficiency, and torque density are needed, such as Toyota Prius, etc.

In this application note, two external magnetic gear systems with parallel axes will be studied [1],[2]. The analyzed magnetic gears are made of two different shapes: radial and parallelepiped permanent magnets.

Linear actuators have many applications ranging from domestic to industrial. Their role consists of converting many forms of energy such as electrical energy, hydraulic energy etc to a mechanical linear motion.

Magnetic gears (MG) which achieve contactless power transmission are increasingly attracting the interest of industry. Traditional mechanical gears suffer from several weaknesses: friction losses, lubrication issues, heat, vibration and noise. Magnetic gears are therefore developed to overcome the issues accompanying the use of traditional mechanical ones.

In this paper, an FEM simulation of brushless DC motor using EMWorks2D is established. The model is created using MotorWizard inside SOLIDWORKS. Magnetic flux and Torque results are generated verus rotor angle.

Zahnräder und Getriebe werden verwendet, um die Geschwindigkeits- und Drehmomentübertragung in verschiedenen Anwendungen zu variieren.

Ein geschalteter Reluktanzmotor (SRM) ist eine rotierende elektrische Maschine, bei der sowohl der Stator als auch der Rotor ausgeprägte Pole aufweisen (Abbildung 1). Die Statorwicklung umfasst einen Satz von Spulen, von denen jede auf einen Pol gewickelt ist.

Elektromagnetische Aktuatoren sind elektromechanische Komponenten, mit denen elektrische Energie in eine mechanische Bewegung umgewandelt wird. Sie decken translatorische und rotatorische Bewegungen ab. Gleichstromaktoren bestehen im Allgemeinen aus Permanentmagneten, Magnetspulen und ferromagnetischen Teilen.

Magnetische Aktuatoren wandeln mithilfe elektromagnetischer Felder elektrische Energie in mechanische Energie um. In Abhängigkeit von der Bewegung, ob es sich um eine Translation oder eine Rotation handelt, werden die Antriebe in zwei Hauptkategorien eingeteilt, nämlich Linear- und Rotationsantriebe.
