Product Description

Instruction for WS-3H15high-efficiency brushless dc motor drivers
DC voltage15VDC-50VDC
PWM Frequencyover 12KHZ
 Input signacompatible with TTL
The most driving current15A
size118*75*33 mm


1. +AT,-AT port is outside DC power supply     
2.U port for motor U pin
3. V port for motor V pin
4. W port for motor W pin
5. +5V for sensor power
6. GND for sensor or control GND
7. HALL A is sensor A input
8. HALL B is sensor B input
9. HALL C is sensor C input
10. CW is for motor forward direction, active low
11. CCW is for motor reverse direction, active low
12. AD for motor speed(0-5V or 0-10V)
13. BRAKE port is braking input end,low level.
14.The driver has ACCpotentiometer for start-up accelerationc, accelerating time from 0.1s to 3s, To adjust accelerating valuet with power off. Out-factory setting 0.1S.
15. SUB SPEED potentiometer is for auxiliary rotate speed adjustment.Different motor parameter need below adjustment.DA input voltage adjusted to 5V,if motor ingspeed is not the highest speed, To rotate SUB SPEED potentiometer clockwise until motor reach to the max speed.
If DA port is less than 5V,motor has reached the max speed, DA port adjust to 5V now. To rotate SUB SPEED potentiometer anti-clockwise until motor reach to the max speed.
1.DC voltage 15VDC-50VDC
2.Most output current 15A
3.insulating resistance over 500MΩ
1.cooling method: naturally and imperatively
2.condition;avoid soot and corrosive air
3.temperature: 0ºC-+50ºC
4.humidity: 40-89%RH.
The power supply works between DC15V to DC50V
A complete brushless DC motor driver control system includes brushless DC motor, brushless DC motor driver,DC power and control signal.Below is typical system chart.
