Multipolar PMSM with wide power for fully electric drive system

This paper attempts to present an optimal design strategy and characteristics of multipolar permanent magnet synchronous motor(MPMSM) with wide power for fully electric drive system(EDS). The structures of stator lamination, rotor lamination and stator winding are analyzed. And how temperature influences the performance of the motor is presented. Moreover, how to calculate air-gap length and the size of permanent magnet of MPMSM are discussed.
