EMS is a 3D electromagnetic field simulator software suite, based on the powerful finite element method. Currently, it is the only electromagnetic Add-in available to SOLIDWORKS users. EMS is Gold Certified by SolidWorks® and targets four main areas: electromechanical, electromagnetic, power electronics, and electromagnetic behavior. This makes it ideal for motor development and testing, generator projects, metal detector design, Eddy current simulation, transformer simulation, induction heating modeling, magnetizing and much more.
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.
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.
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.
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.
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.
