摘要
This paper proposes a novel technique of torque ripple minimization of brushless de motor. The stator current has been synthesised based on sector selection and a novel switching technique by modifying the three phase supply currents of the BLDC motor drive. The trajectory of the modified current vector has been determined by vector approach in stationary plane. The commutation judgement determines the normal conduction period and commutation period by tracking the mode of operation according to the speed. Based on this analysis, the calculated optimal phase angle compensates the current commutation error. The performance of the proposed drive with phase compensation of synthesized currents ensures to minimize the torque ripple. The effectiveness of proposed strategy is validated by experimental results.
