EMS is a true multi-physics software and simulation package. It enables you to couple your magnet, magnetic, and electrical design to Thermal, Structural, and Motion analyses on the same model and mesh in a hassle-free integrated environment without any need to import, export any data. This integrated multi-physics environment means: no cluttering, no jumping around, no mishmashing, no chaos, no confusion, and no mess.
It also means: efficiency, accuracy, and productivity. Your design involves electro-thermal aspects? Easy and hands-free! Just check "Couple to thermal" steady-state or transient in the study properties.
EMS automatically computes the joule, eddy, and core losses and feeds them into the thermal solver. You may readily add non-electromagnetic heat loadings by applying volume heat, heat flux, or simply fixed temperature. Taking into account the environment conditions such as convection and radiation, EMS thermal steady-state or transient computes the temperature, temperature gradient, and heat flux and saves them to "Thermal Results" folder. By the same token, the electro-mechanical coupling is also easy and hands-free.
The "Couple to structural" option invokes the EMS structural solver, after transferring the local force distribution in relevant parts in addition to the mechanical loads and constraints, and then computes the displacements. The stress and strain are deduced subsequently and added to the "Structural Results" folder as well. If the more general electro-thermo-mechanical coupling is desired, EMS transfers both the thermal and structural loads to the Thermal and Structural solvers.
The Thermal solver, in turn, feeds the thermal loads to the Structural solver which computes the final displacements that reflect both the electromagnetic and the thermal loads while taking into account the magnetic, electrical, thermal, and structural environments.
Electrical machines and drives usually encompass moving parts and components. Generally speaking, the resulting motion is simply rotational such as motors or translational such as linear actuators.
Nevertheless, some applications such MagLev and Eddy current braking may provoke all the motion six degrees of freedom. In such case, only EMS can handle such intricate machines and equipment. That is it and that is all. Consequently, you can simply grab a CAD model from the depositories, make necessary changes, and start your finite element analysis instantly.
Electromechanical, electromagnetic, and power electronics devices can readily be studied using EMS. Electromagnetic behaviour could also be investigated with EMS. Electrostatic approximation rests on the assumption that the electric field is irrotational, i.
From Faraday's law, this assumption implies the absence or near-absence of time-varying magnetic fields, i. 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.
The Electrostatic module can help study a large number of devices and address numerous insulating and conducting phenomena. This phenomenon is common in high voltage and high power applications. The Magnetostatic module can help study a large number of devices and address numerous magnetic and electromechanical phenomena.
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. 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. The Electric Conduction module can help study a large number of devices and address numerous conducting and joule effects.
The AC Magnetic module can help study a large number of devices and address numerous magnetic and eddy current effects. This technology is typically used in pipe inspection for the oil and gas industries. The Transient Magnetic module can help study a large number of devices and address numerous magnetic, eddy current, and transient effects.

Published paper link. The model equations, which can be readily implemented in software, are the result of a systematic approach that starts from the equations for the selfinductance of a wire and the mutual inductance of two parallel and misaligned wires that lie on the same plane. Accuracy is guaranteed by considering all the magnetic interactions among the individual turns in the two coils, while the simplifications involve only the calculations made at the corners of the coils.
The model was validated by taking as reference experimental measurements carried out on a rectangular and a square magnetic coupler. A second analytical model, based on equivalent single-turn coils, was also tested for comparison purposes.
The validation was extended with Finite Element Analysis FEA tools by considering a wide range of coil side lengths, air gaps, number of turns and lateral misalignments. The proposed model can, therefore, be regarded as a reliable tool to aid in the design of rectangular-shaped air-core magnetic couplers with applications in the contactless transfer power that are not necessarily limited to vehicle electrification.
