This paper addresses the active torque ripple compensation of a permanent magnet brushless direct-current motor (PMBLDC) drive with new pulse width modulation (PWM) technique and advance angle method. Torque is well-known problem in BLDC motors which produced by discrepancy between stator current back electromotive force (back-emf) waveforms. The advanced method proposed this generates maximum ...

In this paper, an adaptive current controller is proposed for variable speed brushless direct (BLDC) motor drives to minimize the output torque ripples caused by parametric and periodically varying uncertainties. Phase-to-phase non-ideal back-electromotive force (back-EMF) in BLDC changes with respect shaft angle, hence period of these signals alters depending on rotor frequency. To address pro...

It is estimated that by 2030, Battery EVs will become mainstream for passenger car Even though gaining interest transportation, the future of EV power transmission facing concerns and open research challenges. Considering case torque ripple mitigation improved reliability control techniques motors, many motor drive ...

Cogging torque is the major limitation of axial flux permanent magnet motors. The reduction of cogging torque during the design process is highly desirable to enhance the overall performance of axial flux permanent magnet motors.
