Application notes:

JYQD_V8.3E driver board is bare board without housing and heatsink. If the power of the motor below 60W ,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 60W, it must add heatsink like the diagram as below.

Please take note that JYQD_V8.3E driver board has no anti-reverse connection protection, it will permanently damage the driver board if reversed polarity connection.

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.

The “M” terminal on the JYQD_V8.3E driver board is the motor speed pulse output signal (push-pull output), and the maximum output current is less than 5mA.

Wiring Diagram:

5V -----Driver board internal output voltage

M ---- Motor speed pulse signal output port, 5V pulse signal.

1. Control port

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


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:3.96 mm

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

Dimensional Drawing:

♦When using this motor drive module to adjust the speed, the motor will have excessive current at high speed, the speed will be unstable, and the efficiency will be reduced.
When using this motor drive module to adjust the speed, the motor reverses at the start, the current is large, and the motor starts to shake.
The above situation proves that the matching degree between the motor and the drive module is low. Please ask the customer service to adjust the data. You can replace the hardware resistor and capacitor to achieve the best driving effect.
♦ If you use less than 60W, you don't need to add heat sink. If you use more than 60W, you must add heat sink without heat dissipation.
The driving efficiency of the chip is reduced. If the temperature is too high, it will cause permanent damage! The area of ​​the heat sink depends on the working environment (recommended heat dissipation surface area is more than 200 square centimeters)! When installing the heat sink, be sure to pay attention to the insulation problem. If it is not insulated, it will cause The drive board is permanently damaged!
♦The power supply can't be reversed, and the reverse will be broken immediately! Therefore, it is necessary to make sure that the polarity of the power supply is not connected before wiring.
♦ The phase lines of the three motors can be connected freely. If the direction is reversed, you can reverse the two phase lines.
♦ 5V on the driver board is only used for external potentiometer speed control. Do not connect other power equipment, otherwise it will be damaged.
♦ This drive board is connected to the speed potentiometer 1-30K, it is recommended to use 10K potentiometer

We can supply extra assy as connector wires and heatsink.
