“…In light of the limitations of modeling IPM by using explicit parameters, several significant research efforts have been made in recent years towards finding numerical simulation solutions that directly link electromagnetic field and electric circuit [11][12][13][14][15][16][17]. Such attempts try to retain the advantages of finite element analysis (FEA) by coupling FEA with electric circuit analysis.…”

This paper focuses on a novel modeling method for Interior Permanent Magnet (IPM) synchronous machines. This modeling method is based on a stator winding flux linkage table that is obtained from experimental testing. As indicated by the comparison between computer simulation and dyno testing, this modeling approach can model the nonlinear behavior of Interior Permanent Magnet synchronous machines with high fidelity without adding significant computational loads.

We present an approach for directly coupling transient magnetic fields and electric circuits. The circuit can contain arbitrarily connected solid conductors located in the magnetic field region. A systematic procedure suitable for both nodal method and loop method is used to couple fields and circuits. The structures of the system equations of the two methods are analogous. The formulations allow the equations in stranded windings and solid conductors to be unified and the coefficient matrix of the system equations to be symmetrical. In order to reduce the solution domain, the periodic boundary conditions are still applicable when the solid conductors are involved. Our approach has been applied to the simulation of electric machines. We give four examples: 1) calculation of the input phase current and output torque when a single-phase induction motor with shaded rings is in locked-rotor operation; 2) simulation of the sudden short circuit of a synchronous generator with starting cage; 3) study of the phase current waveform of an induction motor when the rotor bars are broken; and 4) investigation of the parasitic capacitive impact of the surge voltage on a winding due to drive switching and cable ring.

“…The slow varying fields are understood to be the field that does not lead to current redistribution [112][113][114] . On the other hand, we can say that there are no eddy current effects as the dimensions of the current carrying conductors that are smaller than the penetration depth of the field.…”
