Abstract

The effect of slots poles combination on inductance and torque was investigated on the motor with outer rotor bonded NdFeB Halbach cylinder designed for automotive application. Motor with Halbach rotor has better performance with higher number of slots and poles combination. The magnet eddy loss was calculated and analyzed with different slots poles. The impact of rotor back on the eddy current was also investigated. The eddy loss calculated using 3D FEA models were also compared with 2D and shows a big difference between the two
