400A 400B 400W brushless dc motor speed control board circuit board for general machine 110v 120v 180v dc motor speed controler

Brief Introduction

The 400A/400B/400W adopts the DC servo control method to realize the double closed-loop control of the motor current and speed. Through the double closed-loop control, the current of the motor will not be affected by the change in the speed, so the dc motor can be used within the rated current range. best effect. Make the controlled motor work stably under the rated parameters, make the motor run at low speed and have a large torque, and at the same time, it can effectively protect the motor in the case of a motor stall. It has the advantages of fast motor response, good linearity, large low-speed torque, energy saving, and durability. The professional-grade EMC-EMI design enhances the adaptability of the speed control board to the industrial environment, reduces the probability of failure of the speed control board, and prolongs the service life of the carbon brush of the DC motor, thus bringing users the best experience in use. It is convenient and greatly improves the cost performance of the speed control board. This new type of control board can be widely used in the fields of numerical control machine tools, automation equipment, printing machinery, packaging machinery, and the like.

Wiring method and description

1. Adjust speed directly

-Connect to the high-speed end of the potentiometer, + to the low-speed end of the potentiometer, and CP to the adjusting end of the potentiometer.

IN is connected to the high-speed end of the potentiometer, 0V is connected to the low-speed end of the potentiometer, CP is connected to the adjustment end of the potentiometer, and -12V is connected to IN to work.

Note: The 4K7 potentiometer can be replaced by a displacement controller or a thin film potentiometer for passive tracking control, and it can operate synchronously with the main motor.

2. Controlled by displacement controller

+12V is connected to the red wire of the displacement controller, GND and -12V are connected to the black wire of the displacement controller, INW is connected to the output signal of the yellow or blue line of the displacement controller (yellow line: block the deceleration to stop working, blue line: block the acceleration to work at full speed).

0V is connected to the red line of the displacement controller, -12V is connected to the black line of the displacement controller, IN is connected to the output signal of the yellow or blue line of the displacement controller (yellow line: block the deceleration to stop working, blue line: block the acceleration to work at full speed).
