Virtual design optimization of a BLDC motor for a two wheeler electric cargo vehicle

This paper focuses on developing an optimized design of a brushless DC motor (BLDCM) for an electric two-wheeler cargo vehicle. Designing an electric motor for a two-wheeler presents several challenges as the design must be highly optimized for size, mass and cost while also delivering the required torque and speed at various loads and road gradients. The motor design presented in this paper takes the aforementioned considerations into account and focuses on the optimization of motor design. The optimization of motor design is performed using response surface methodology while considering the design of the motor as a multiple response problem. The designed motor is further analyzed using 2-D finite element analysis (FEA) and the performance charts of the motor are obtained.
