The speed of the dc motor controller is how to change

The running speed of the dc motor controller to change? Below small make up for it. 1. Adjust the armature voltage. Through the study of the change of the armature voltage, so as to change the speed. This method has fast dynamic response, suitable for a wide range of stepless smooth speed regulation system. 2. Through to weaken the main magnetic flux of the motor, make the speed of the motor from the rated speed rise, this way of dynamic response is slow, although can be stepless smooth speed regulation, but the speed range is small. 3. The armature of the armature loop resistance R of the motor controller series resistance to change, so as to realize speed regulation. But only change speed and poor smoothness, and mechanical properties of soft, low efficiency. Above is the rotating speed of dc motor controller introduces, hope to help everyone.
