Abstract

BLDC Motor with high torque and wide speed range is the primary requirement for in-wheel electric vehicle application. Radial flux permanent magnet (RFPM) brushless direct current (BLDC) motors are the solution for electric vehicles, because of their shape, flexibility, compactness, robustness, high efficiency, wide speed range and high torque. In this paper, RFPM BLDC motor is proposed for wide range of speed conrtrol. It has single side configuration with 24 stator poles and 36 permanent magnets (PM) on rotor disc. In most of the applications of RFPMBLDC motor, the speed control is very important. To achieve accurate speed control, closed loop control using microcontroller is proposed in this paper. Microcontroller is used to drive the motor by sensing rotor position using Hall sensors. The effective braking scheme is also proposed. To verify the performance of the proposed RFPM BLDC motor, simulation is carried out and results are analysis. A prototype of RFPM BLDC motor is designed in order to validate the performance of the motor.
