Design of a High Power density Halbach BLDC Motor for Electric Vehicle Propulsion.

Abstract

Electric vehicles (EV) are the need of the day for future transportation. The electric drives used for vehicle propulsion need to be highly efficient and high power dense to improve the performance of EVs and make them competent in transportation applications. In the similar lines this paper proposes a Radial Flux BLDC motor with surface magnet rotor with a halbach array. The complete design of motor is carried out, nonlinear magnetic analysis carried out and arrived at performance characteristics. The proposed topology is compared with conventional BLDC motor and found an increment of 20% in torque density. The hardware is realized and tested for its performance
