This paper investigates the electromagnetic and structural characteristics of a spoke type BLDC motor and provides a comparative study with respect to Interior Permanent Magnet motor (IPM).The electromagnetic analysis aims to determine the average torque and cogging torque of spoke type BLDC motor. The natural and induced vibration characteristics of the motor are evaluated by performing structural fi nite element analysis. The electromagnetic and vibration characteristics are assessed for diff erent slot/pole combination to provide an insight on their infl uence on the performance of the motor. In addition, thermal analysis is performed to predict the temperature distribution and a comprehensive analysis of spoke type BLDC motor is presented.
