JUYI Brushless DC Motor Driver JYQD-V6.5E O.V / L.V Protection PWM Frequency 1-20KHZ
Application notes:
1. Confirm that the voltage and power paraparameters of the motor not exceed the range 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 us for guidance)
3.JYQD-V6.5E is driver board without housing and heatsink, it can drive the BLDC motor below 70W without any heatsink,but needs normal ventilation.
4.The "5V" pin on the driver board is forbidden to connect with external power equipment.it is only suit for external potentiometer or switch for speed adjustment,reversing and singnal swtiching operation.
5.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.
Description of wiring:
1. Control port
5V — Driver board internal output voltage, for external potentiometer or switch for speed adjustment and reversing operation
Z/F — Rotating direction control ports. Connect “5V” high level is Forward direction,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-10KHz; Duty cycle 0-100%
Signal —Speed pulse signal output
GND —Used for Driver 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)
2. Power port
MA ----motor phase A
MB ---- motor phase B
MC---- motor phase C
GND --- DC -
VCC --- DC +
3:Remarks
a. 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.
b. Control port distance: 2.54mm,Power port distance:3.96 mm
c. Pay attention to the insulation between the driver MOSFET and the heatsink or the installation plate.
