DC governor is a motor speed control device, including motor DC governor, pulse width DC governor, thyristor DC governor, etc., generally modular DC motor governor, set of power supply, control, drive circuits in one, using three-dimensional structural layout, the control circuit adopts the micro-power components, with photocouplers to achieve the isolation of the current, the voltage conversion, the circuit's proportionality constants, integration constants The proportional constant, integral constant and differential constant of the circuit are adjusted by PID adapter. With small size, light weight and other characteristics, can be used alone or directly installed in the DC motor to form an integrated DC speed motor, can have all the functions due to the governor.
DC governor is to adjust the speed of DC motor equipment, because DC motor has a low speed and large torque characteristics, AC motor can not be replaced, so adjusting the speed of DC motor equipment - DC governor has a wide range of applications.
Applicable occasions
The following occasions require the use of DC governor:
1. Wide speed range is required;
2. Fast dynamic response process is required;
3. Automatic and smooth over process is required for accelerating and decelerating;
4. High torque is required for low-speed operation;
5. Good excavator characteristics, can automatically limit the overload current to the set current.
The above five points are also the application characteristics of DC governor.
Applications
Numerical control machine tools, papermaking and printing, textile printing and dyeing, fiber optic cable equipment, packaging machinery, electrical machinery, food processing machinery, rubber machinery, biological equipment, printed circuit board equipment, experimental equipment, welding and cutting, light industrial machinery, logistics and transportation equipment, rolling stock, medical equipment, communications equipment, radar equipment, satellite ground receiving system.
