Dc motor controller speed regulating mode analysis

Dc motor controller is able to direct the electric energy into mechanical energy to the rotation of the motor controller, it can realize electric energy and mechanical energy conversion to each other. Its speed can be adjusted within the prescribed scope, and the adjusting method is more simple. We will follow below small make up to get to know. 1. The armature voltage control: use the armature voltage regulating speed input. This way need power supply, dc motor controller is generally controlled rectifying power supply. 2. Magnetic field control: use the adjustment speed of exciting current. This way of speed adjustment, by reducing excitation current, to reduce the air gap magnetic flux, make the equipment run faster. 3. The use of access control resistance, for speed regulation. Declare the above three kinds of speed regulation way, each of which has its unique advantages, and the use of occasions. Hope the above said is helpful to you.
