Brushless dc motor controller knowledge popularization

Everybody is good, here small make up to you on the knowledge of popular science the brushless dc motor controller. Commutation circuit of brushless dc motor controller is composed of drive and control, not easy to separate, especially small power circuit, often will both merge into a single application-specific integrated circuit. In the power of the larger motor controller, drive circuit and control circuit can become one. Drive circuit output power, the armature winding and controlled by control circuit. Driving circuit are from linear amplification state into PWM switch state. The above is an introduction to the knowledge of brushless dc motor controller, hope to help everyone.
