© 2017 IEEE. Calculation and matching of the main parameters of a brushless DC (BLDC) motor for a Battery electric vehicle (EV) is studied in this paper. Usually, different shapes of permanent magnet (PM) and different magnetizing methods will affect the performance of the motor. Especially when the motor is designed for an EV, more elements need to be considered, such as efficiency under normal operating conditions and torque ripple. So in this paper the performance of PMs with different shapes and different magnetizing methods will be compared by finite element analysis (FEA). Finally, the structure of the stator and rotor will also be optimized to obtain the required prototype model.
