Design and Analysis of BLDC Motor for Electric Vehicle Application

The extreme use of fossil fuel results in green house gas (GHG) emissions and changes in climate conditions. This leads to change the mode of transportation from IC engine vehicle to electric vehicle (EV). The most important criterion for an EV is the selection of the motor. Nowaday the use of permanent magnet brushless DC motors (BLDC) in EV application is increasing because of its better torque speed characteristics comparing with other motors, high efficiency, fast response at high operating speeds, small size and simple to control in speed reversal. This paper analyses the performance of a 750 W, 48 V BLDC motor for EV using finite element analysis in using Ansys Maxwell (2D). The performance characteristics of the designed motor are validated experimentally.
