Quick mastery of the brushless motor controller control circuit

Control circuit is used as the control of the brushless motor controller speed, steering, current ( Or torque) And maintenance of motor controller over-current, over-voltage, overheating, etc. The above parameters are easy to imitate signal, use this to control is relatively simple, but from the point of conduct, the parameters of the motor controller should be converted to digital quantity, after digital control circuit to control the motor controller. At present, the control circuit has a special integrated circuit, disposal of the device and digital signal disposal device of three kinds of ways. On the motor controller control request is not high, application-specific integrated circuit of the control circuit is simple and applicable. Adopting digital signal disposal is the future direction for composition control circuit, the digital signal disposal device will be introduced in the following ac synchronous servo motor. We study the brushless motor control circuit of the controller, do you have any new feelings?
