Dc motor controller speed regulating mode analysis

There are many means speed regulation of dc motor controller, small make up take you know about the below. 1. The armature voltage control, the use of the armature voltage input to speed adjustment. At this point, the armature dc motor controller need to use a dedicated to the separate power supply, dc power supply to excitation is provided by another source. 2. Magnetic field control, the use of adjusting excitation current to control size. By reducing excitation current, to the air gap flux decreases, and the rotation speed of dc motor controller will rise. Above is about dc motor controller speed control method is introduced, the user after the understanding of the principle of function of equipment, can according to the regulation in the form of corresponding to improve equipment utilization.
