JUYI Rectangle 3 Phases 12V 24V 36V Hall Sensor Good Quality Motor Driver bldc Motor Controller with Technical Support JYQD-V7.3E2 

Application Instructions

1.Confirm the voltage and power parameters of the motor, which should not exceed the range specified for this drive board.

 2. It is applicable to 120 - degree Hall - equipped DC brushless motors. Note that the winding sequences of motors from different

     manufacturers do not always correspond one - to - one with those of the drive board. Customers can adjust the Hall winding

     sequence or the three - phase winding sequence of the motor according to the actual situation to achieve the optimal driving effect .

3. The JYQD_V7.3E2 drive board is a bare board. For motors with a power below 100W, forced heat dissipation is not required,

    but normal ventilation must be ensured.

4. The 5V output port on the drive board is prohibited from being connected to external electrical equipment. It is only suitable for

     connecting external potentiometers and switches on this board for speed regulation and reversing.

5. The Signa on the JYQD_V7.3E2 drive board is the motor speed pulse output signal, with an output current of less than 5mA.

Wiring Diagram

1. Hall Port (Upper Left)
● GND: Negative interface for Hall signal.
● Hc: Hall signal Hc.
● Hb: Hall signal Hb.
● Ha: Hall signal Ha.
● 5V: Positive interface for Hall signal.

2. Control Port (Lower Left)
● GND: Internal control ground of the drive board.
● VR: Speed control port. Analog voltage speed regulation ranges from 0V - 5V, with linear speed regulation from low to high.

For PWM speed regulation, it needs to share the same ground as the drive board.
● Z/F: Forward - reverse control port. Connecting to 5V or leaving it floating makes it rotate in one direction, and connecting to

GND makes it rotate in the other direction.
● Signal: Motor speed pulse signal output port, 5V pulse signal.

● EL: Enable control. Connect to 5V to allow operation, and connect to GND to prohibit operation.
● 5V: The 5V output inside the control board is only for powering potentiometers and for switch - based speed regulation and direction change.

3. Power Port (Right)
● VCC: Positive terminal of the DC power supply (+).
● GND: Negative terminal of the DC power supply (-).
● MC: One of the three - phase lines of the motor.
● MB: One of the three - phase lines of the motor.
● MA: One of the three - phase lines of the motor.

4. Note that the motor phase lines and Hall lines should not be too long, as overly long wires can cause signal interference problems.

5. For the control port, the port pitch is 2.54mm. For the power port, the port pitch is 3.96mm.

6. When adding heat sinks or installing, pay attention to the insulation of the power transistors on the drive board.
