The Influence of Magnetic Materials Technologies on the Design of IPMSM for Automotive Applications

Future electric car issues that need to be addressed (EV) are mainly the power/energy densities of the energy storage systems and the electric motor performances. Interior Permanent-Magnet Synchronous Machines (IPMSM) are commonly utilized in today's electrical automobiles because they have a wider constant power speed range and a better power/torque density, a compact structure, a higher efficiency than induction machines. Magnetic steel sheets are frequently utilized in IPMSM, and the usage of low-iron-loss materials in IPMSM to increase performance has recently been investigated. This paper deals with a study on the influence of Different magnetic steel sheets technologies on the design of IPMSM for automotive applications. The designed IPMsynchronous motors results of the simulation In terms of efficiency, torque and output power, various magnet material components are compared to one another.
