Abstract

High torque and wide field weakening region are two parameters needed for electric vehicle. In order to achieve those requirements, variation of pole numbers of an interior permanent motor utilizing the same stator geometry is performed in this study. Slot harmonics are also compared in connection with the losses produced. All calculation are analytically performed and the motor characteristic is presented in the form of torque versus speed graph.
