JYQD-V6 series driver board are appropriate for 3 phase brushless direct current electric motor(without hall sensor).It owns compact structure, integrated functions and long service life. The function include PWM speed control, overlow voltage protection and speed pulse signal output etc. It is widely applicated in logistic automation, fans, blowers and electric water pumps. We also provide customized service and technical supports.

MA ----motor phase A
MB ---- motor phase B
MC---- motor phase C
GND----DC-
VCC----DC +
5V -----Driver board internal output voltage
SC---- Motor speed pulse signal output port, 5V pulse signal.
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, connect with GND when input PWM speed regulation, PWM frequency:1-20KHZ; Duty cycle 0-100%
GND—Used for Drive board internal control
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:2.54mm
5.Pay attention to the insulation between the driver MOSFET and the heatsink or the installation plate
1.Confirm that the voltage and power parameters of the motor not exceed the range of the driver board as specified.
2.JYQD-V6.7 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.
3.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.
4.This BLDC motor 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 (see the attachment for how to do the adjustment)
5.Please take note that JYQD-V6.7 driver board has no anti-reverse connection protection, it will permanently damage the driver board if reversed polarity connection.
6.The “SC” terminal on the JYQD-V6.7driver board is the motor speed pulse output signal (push-pull output), and the maximum output current is less than 5mA.
