12-36VDC Max power 500W Arduino control JYQD-V7.3E2 Hall effect BLDC motor driver board
1. Please confirm that the voltage and power parameters of the motor not exceed the range as specified.
2. This BLDC motor driver applicable to hall effect brushless dc motor with Hall at 120°, not all manufacturers' Hall line sequence are corresponding, you can adjust the Hall line sequence or motor three-phase line sequence according to the actual situation, to achieve the best driving effect.
3. JYQD-V7.3E2 is the driver board without housing and heatsink, it can drive the BLDC motor below 100 watt without any heatsink, but needs normal ventilation.please add heatsink if the power more than 100W.
4. Please do pay attention to the insulation between the BLDC motor driver MOSFET and the heatsink or the installation plate.
1. Control port
|5V —Driver board internal output voltage, external potentiometer or switch for speed adjustment and reversing operation
|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%
|EL —Enable port control. Connect 5V or no connect to allow operation, connect GND to forbid operation.
|Signal— Speed pulse signal output
|GND—Used for Driver board internal control
