Mitigation of Commutation Torque Ripples in Permanent Magnet Brushless DC Motor [PDF]

open access: yesUniversal Journal of Electrical and Electronic Engineering, 2013
In a conventional three phase Brushless DC machine with 120° electrical conduction, Harmonics and commutation torque ripple occurs because of changeover of load current from one phase to another at every 60 electrical degrees. This paper presents techniques for diminishing the harmonics and torque ripples in sensor Brushless DC motor.
