Application Guidelines

1. Confirm that the voltage and power parameters of the motor not exceed the range as specified.

2. JYQD-V8.8B is driver board without housing and heatsink, it can drive the motor below 100 watt without any heatsink, but needs normal ventilation.

3. The 5V output port on the drive board is forbidden to connect external power equipment. It is only applicable to external potentiometer or switch for speed adjustment, commutation and enabling operation

BLDC Motor Driver’s Wiring

1. Control port

5V —Driver board internal output voltage, external potentiometer or switch for speed adjustment and reversing

operation

Z/F —Rotating direction control ports. Connect “5V” high level or no connect is Forward direction, connect 0 V low level or

connect to GND is reverse direction.

VR —Speed control port. Analog voltage linear speed regulation 0.1v -5V, The input resistance is 20K Ohm ,connect with GND when input PWM speed regulation, PWM frequency:1K-20KHZ; Duty cycle 0-100%,PWM amplitude:5V

M— Speed pulse signal output,5V pulse signal

GND—Used for Driver board internal control

2. Power port

MA ----motor phase A

MB ---- motor phase B

MC---- motor phase C

GND ----DC-

VCC----DC +

4. Use shielded wires if the drivers board has more than 50 cm distance from the motor, otherwise it may lead to abnormal driving, affecting the normal use

5. Control port distance: 2.54mm,Power port distance:3.96 mm

6. Pay attention to the insulation between the driver MOSFET and the heatsink or the installation plate.
