Hall Sensor Brushless DC Motor Driver Board 7-48V 10A, PWM/Analog Speed Control, -20°C to 85°C

Hall Sensor Brushless DC Motor Driver Board 7-48V 10A, PWM/Analog Speed Control, -20°C to 85°C

Application Notes

1. Motor Parameter Verification  

   • Voltage & Power: Confirm the motor’s voltage and power parameters must not exceed the driver board’s

      specified limits (e.g., 7-48V DC, 8A continuous/10A peak).  

2. Compatibility & Wiring Adjustments  

  • Applicability: Designed for 120-degree Hall sensor-equipped brushless DC motors.  

  • Wiring Flexibility:  

     - Not all manufacturers’ phase sequences (motor or Hall sensor) align with the driver board.  

     - Adjust the Hall sensor wiring or motor phase sequence for optimal performance.  

3. Thermal Management & Ventilation  

   • Bare Board Design: The JYQD_V7.3B is a bare board  

   • Heat Dissipation:  

     - ≤100W motors: No forced cooling required; ensure adequate ventilation.  

     - >100W motors: Install heatsinks or active cooling.  

4. 5V Port Usage Restrictions  

  • Function: The 5V output port solely supports external potentiometers or switches for speed regulation

     and direction reversal.  

  • Prohibition: Do not connect other external devices to this port.  

5. Signal Port Specifications  

   • Signal Output: The “Signal” port provides a 5V pulse signal proportional to motor speed (RPM).  

  • Current Limit: Output current is <5mA; avoid overloading the port. 

Wiring Diagram

Port Description

I. Hall Sensor Port (HALL) • GND: Ground terminal for Hall sensor signals. • Ha/Hb/Hc: Hall sensor phase signal inputs (Ha, Hb, Hc). • 5V: 5V power supply for Hall sensors. II. Control Port (SET) 1. GND: Internal control ground of the driver board. 2. VR: Speed control port. • Analog mode: 0-5V linear speed adjustment (0V = min, 5V = max). • PWM mode: Requires shared ground with the driver board. 3. Z/F: Forward/reverse control. • Forward: Connect to 5V or leave floating. • Reverse: Connect to GND. 4. Signal: Motor speed pulse output (5V signal, <5mA). 5. EL: Enable control. • Enable: Connect to 5V. • Disable: Connect to GND (immediate motor halt). 6. 5V: Internal 5V output exclusively for potentiometers/switches (speed/direction control). III. Power Port • P+: DC power supply positive (+). • P-: DC power supply negative (-). • MA/MB/MC: Three-phase motor terminals (connect to motor windings). IV. Key Notes 1. Cable Length: • Avoid excessively long motor phase or Hall sensor cables to prevent signal interference.

2. Port Spacing: • Control port: 2.0mm pitch. • Power port: 3.96mm pitch. 3. Heat Dissipation: • Ensure proper insulation when installing heatsinks or mounting the driver board.
