Abstract

Today, the two most commonly used machine types in electric vehicles are the permanent magnet synchronous machine (PMSM) and the induction machine (IM). IMs have several advantages, such as robustness, cost-effectiveness, and rare-earth-metal-freeness. However, IMs are more complex to control than PMSMs since there are several possible slip rate choices for one desired output torque and speed combination. Thus, to find the optimal operating points, a considerable number of finite element method (FEM) simulations may be required. Furthermore, since there are windings in both the stator and the rotor, the FEM simulation computation time for a single operating point of IMs becomes substantially high compared to the one for PMSMs.
