Abstract: This paper describes a simpler way to control the speed of PMBLDC motor using pwm control method. The performances of the PMBLDC system are found from the hardware implementation. The speed is regulated by PI controller. The method proposed suppresses torque oscillations. This drive has high accuracy, robust operation from near zero to high speed. This paper deals with control method to reduce speed oscillations.

Keywords: Hall position sensors, permanent magnet brushless DC motor, pwm, PI controller.
