The micro-motor is essentially a DC electric motor. After the power is turned on, the speed is usually high, at least several hundred revolutions per minute, and the higher point can reach tens of thousands of revolutions. In this case, the torque of the motor is very small and it cannot drive heavy Something, but due to the characteristics of micromotors with low speed and high torque, AC motors cannot be replaced by this, so that we can adjust the speed of the micromotor through the reducer, and can also achieve stepless deceleration through the electronic governor. purpose.
As the center of the micro-motor, the DC speed reducer is the key equipment for adjusting the micro-motor speed. The upper end is linked with the AC power supply, and the lower end is connected with the micro-motor. The DC governor converts the AC power into two output DC power supplies, one input to the micro-motor. The neodymium magnet (stator) is input all the way to the armature (rotor) of the micromotor. The DC governor regulates the DC motor speed by controlling the armature DC voltage. At the same time, the micromotor provides a feedback current to the governor. The governor judges the speed of the micromotor according to the feedback current, and corrects the armature voltage output if necessary to adjust the motor speed again.
DC governor in CNC machine tools, paper printing, textile printing and dyeing, cable equipment, packaging machinery, electrical machinery, food processing machinery, rubber machinery, biological equipment, printed circuit board equipment, laboratory equipment, welding cutting, light industrial machinery , Logistics transportation equipment, rolling stock, medical equipment, communications equipment, radar equipment, satellite ground receiving systems and other industries are widely used.
