MINIMIZATION OF COGGING TORQUE IN AXIAL FLUX PERMANENT MAGNET BRUSHLESS MOTOR WITH CERTAIN DESIGN

Abstract

This paper deals with performance of an Axial Flux Permanent Magnet Brushless Motor for the low speed applications. Axial Flux Permanent Magnet Machines are high torque density motors and suitable for Electric Vehicles which reduces the total energy consumption for personal transportation. Normally the rated power of electric motor for Electric Vehicle varies from 10 to 75kW. For the investigation, 26kW single sided Axial Flux Machine has been taken and designed using Finite Element Method. The cogging torque is also minimized for the single stator-single rotor Axial Flux Permanent Magnet Motor which will improve the torque density of the motor to meet the requirements of Electric Vehicles at low speed conditions
