Are induction cookers safe?
EMS EMWorks2DCooking is one of the oldest of technologies and for obvious reasons: humans would never have survived (let alone thrived) without perfecting the art of feeding themselves. The basic idea of cookery—heating food to kill bacteria and make something tasty—is fairly prehistoric: "food plus fire equals cooked food" is roughly how it goes. There's not an awful lot of difference between roasting a hunted animal on an open outdoor fire, as our ancestors would have done, and cooking it with electricity or gas in an oven, as we do today [1]. That's not to say there's been no progress in cooking technology
Switched Reluctance Motor for Electric Vehicles
EMS EMWorks2D MotorWizardThe switched reluctance motor (SRM) is a type of motor doubly salient with phase coils mounted around diametrically opposite stator poles. There are no windings or permanent magnets on the rotor. The rotor is basically a piece of (laminated) steel and its shape forms salient poles. The stator has concentrated coils. Switched reluctance motors (SRM) have a simple and robust structure, thus they are generally suitable for high-speed applications. High-speed motors have the advantage of high power density, which is an important issue of traction motors in electric vehicles (EV). Therefore, high speed SRM seems to be promising candidates for this application.
Eddy Current Simulation of an Inductive Proximity Sensor
EMS EMWorks2DThe inductive sensor is responsible to detect the position of a movable target accurately by measuring the change in inductance of a PCB coil. By connecting this coil to an appropriate circuit, one can correlate between the proximity and the inductance measured. EMS is used to compute the inductance of the PCB coil at various positions of the target. This can help the circuit designers to create a circuit that can accurately measure this change in inductance.
3 phase high voltage submarine power cables and their impact on marine ecosystem – How EM Simulation can help engineers design eco-friendly power transmission cables
EMS EMWorks2DA submarine power cable is a major transmission cable for carrying electric power below the surface of the water. These are called "submarine" because they usually carry electric power beneath salt water (arms of the ocean, seas, straits, etc.) but it is also possible to use submarine power cables beneath fresh water (large lakes and rivers). Examples of the latter exist that connect the mainland with large islands in the St. Lawrence River. The purpose of submarine power cables is to transport electric current at high voltage.
