Application Notes:

1. Confirm that the voltage and power parameters of the motor not exceed the range of the driver board as specified.
2. This driver board is used for 3-phase brushless sensorless motor, but not suit for all 3-phase brushless sensorless motors directly. If the driving effect is not good (such as starting jitter, reversing, the motor noload working current is too large, the speed is not stable, the efficiency is low, and can’t start-up with load.) Customers can adjust the resistance and capacitance of the driver board according to the actual situation to achieve the best driving effect (Contact with us, we will supply technical support)
3. JYQD-V8.20B driver board is bare board without housing and heatsink. If the power of the motor below 36W ,it does not need to add heatsink, It only needs to ensure normal ventilation and well insulation. If the power of the motor more than 36W, it must add heatsink.
4. Please take note that JYQD-V8.20B driver board has no anti-reverse connection protection, it will permanently damage the driver board if reversed polarity connection.
5. The 5V output port on the driver board prohibits connect external device. It is only applicable to the external potentiometer and switch of the board for speed regulation and reversal.
6. The “M” terminal on the JYQD-V8.20B driver board is the motor speed pulse output signal (push-pull output), and the maximum output current is less than 5mA.
Wiring Diagram:

1. Control port

5V -----Driver board internal output voltage, only used for potentiometer and switch speed regulation and reversing.

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:1-20KHZ; Duty cycle 0-100%

GND—Used for Drive board internal control

2. Power port

MA ----motor phase A

MB ---- motor phase B

MC---- motor phase C

GND----DC-

VCC----DC +

3. 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.


4.Control port distance: 2.54mm,Power port distance:2.54 mm


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