Is the synchronous motor not communicating? Why do you say that brushless dc is a type of synchronous motor? Exclude o
The synchronous motor you are talking about should be the permanent magnet synchronous motor, the difference between him and dc brushless motor:
Ontology is an alternating current, motor also similar, but the dc supply is converting ac square-wave brushless motor winding, permanent magnet synchronous motor is to convert alternating current (ac) to supply sine wave with motor winding. It's just electrical control. Can't see from the outside!
Brushless dc motor is not a smooth direct current, but pulse square wave. Like synchronous motors, speed is associated with frequency of square waves.
