Dc motor controller of three kinds of speed regulation

For dc motor controller, I believe you don't feel strange, is the speed of the device can control and adjust. Below small make up to introduce change the rotation speed of dc motor controller method. 1. Through to the armature voltage adjustment, to change its speed, this method is suitable for a wide range of stepless smooth speed regulation system. 2. Through to the motor controller main magnetic flux are reduced, the upward from the rated speed of the motor speed, this way can stepless smooth speed regulation, but the speed range is small. 3. Through to the armature resistance adjustment, to speed, only have used this way. Above is the several methods for speed control of dc motor controller is introduced.
