WebPMSM and BLDC motors can usually be driven with either six-step commutation or sinusoidal commutation. A motor must have the proper mechanical and electrical design to achieve the benefits of sinusoidal operation as noted above. It is best to ask the manufacturer which drive method is best for a given motor. Sinusoidal operation … WebJun 20, 2024 · The first distinction that’s generally made between various motors is whether they run on AC or DC power. The fundamental difference in operation between an AC and a DC motor is that the speed of an AC motor is controlled by the frequency of the applied voltage and the number of magnetic poles in the motor. For a DC motor, speed is …
