JYQD-V6.5E 36V-72V 700W 3 phase BLDC Electric Motor Controller For Industrial Motor

JYQD-V 6 series is a driver board suitable for three-phase brushless DC motors (without Hall sensor), its structure is complete but functional, stable working and long service life. It has the functions of PWM speed regulation, high and low voltage protection and speed pulse signal output. Widely used in fans, automatic sorting lines, blowers and electronic water pumps. We provide customized service and technical support.

Parameter

Wiring diagram

1.Power port

MA ----motor phase A

MB ---- motor phase B

MC---- motor phase C

GND----DC-

VCC----DC +

2.Control port

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

Signal ---- 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, 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

Torque— For starting torque adjustment use, make sure remove the resistors for fixed-torque on the board before use this function (contact us if you want use this function before using)

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.

Overall diamensions

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 (see the attachment for how to do the adjustment)

3.Please take note that JYQD-V6.5E driver board has no anti-reverse connection protection, it will permanently damage the driver board if reversed polarity connection.

4.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.

5.The “Signal” terminal on the JYQD-V6.5E driver board is the motor speed pulse output signal (push-pull output), and the maximum output current is less than 5mA.
