Understanding the effect of PWM when controlling a brushless dc motor
Motion system designers can be challenged when selecting or developing electronics using pulse-width modulation (PWM) to drive brushless dc motors. Heed some basic physical phenomena to avoid unexpected performance issues, along with general guidelines for using a PWM driver with a brushless DC motor. See diagrams, equations.
