PM synchronous machine comparison for light electric vehicles

The research of rare-earth free alternatives, such as ferrite, hot pressed NdFeB Permanent Magnet Assisted Synchronous Reluctance (PMASR) motor or pure reluctance motor, has potentially interesting implications especially in the perspective of industrial mass production. This paper shows the comparison between a sintered NdFeB PMASR, ferrite PMASR, Synchronous Reluctance (REL) and a Surface mounted PM (SPM) machines with the same overall dimensions, winding arrangement and power supply size. The electromechanical performance have been evaluated and compared, in terms of torque and power. Finally, this research provides a description of the electric supply system in order to accurately and efficiently manage the motors for achieving the requested performance.
