Compared brushless motors and brushless dc motor, has the following advantages:
1, implements the position, speed and torque of the closed loop control; Overcome the problem of out-of-step brushless dc motor; 2, high-speed performance is good, generally rated speed can reach 2000 ~ 3000 RPM; 3, resistance to overload ability is strong, can bear the load of three times the rated torque, rapid start to have instant load fluctuation and requirement of special applicable occasions; 4, smooth running at low speed, low speed running won't produce similar to brushless dc brushless dc motor running. Suitable for high speed response to the requirements of the occasion; 5, motor deceleration dynamic response time is short, usually within a few milliseconds. 6, heat and noise is decreased obviously.
