Do you know brushless motor controller

Everybody is good, here small make up take you to understand what is the brushless motor controller. Brushless motor controller is composed of motor and drive dc motor controller, is a kind of mechanical and electronic products. Because of its using self-control type operation mode, so it doesn't like the synchronous motor controller under variable frequency speed regulation, plus startup winding on the rotor, make its not the load mutation, appear the phenomenon of oscillation and step out. Other medium and small capacity of brushless dc motor, its general using high magnetic energy product of rare earth permanent magnet ndfeb material. Above all, you know about whether the brushless motor controller.
