3. Setup and Wiring

Careful wiring is crucial for the correct and safe operation of the motor controller. Refer to the diagrams below for proper connections.

3.1 Terminal Definitions

• VCC, GND: Motor main power supply input (external DC power supply, 9-60V).
• MA, MB, MC: Motor phase line outputs. Connect these to the corresponding phase lines of your brushless motor.
• Ha, Hb, Hc, +5V, GND: Hall signal power input. These five lines connect to the Hall sensors of your motor. Ensure correct polarity and sequence.
• VR: Speed control signal input. Can be controlled by the onboard potentiometer or an external 0-5V analog signal/PWM duty cycle. Supports dual signal input speed regulation.
• D/R: Positive and negative reversing control interface. Can be connected to an external switch for direction control.
• SC: Speed pulse signal output.
• 5V, GND: Motherboard's internal 5V power supply output (current not to exceed 30mA).
• P: Signal input G: ground external PWM signal input. Amplitude: 2.5V-5V. Frequency: 50 Hz - 20 kHz (best).

3.2 Wiring Diagrams

3.3 Initial Power-On and Hall Wiring Debugging

When connecting a brushless motor with Hall sensors, there are typically five Hall wiring lines: two for Hall power supply (+5V and GND) and three for Hall signal lines (Ha, Hb, Hc). It is critical to distinguish these, especially the power supply lines, to avoid damage.

1. First Power-On: Always debug with low voltage and low current. This minimizes the risk of damage if the Hall wiring sequence is incorrect.
2. Hall Line Sequence: The sequence of the three Hall signal lines (Ha, Hb, Hc) must match the motor driver board's requirements for proper operation. If the motor does not start normally or shakes, try changing the order of the Hall signal lines until smooth operation is achieved.
3. Symptoms of Incorrect Hall Wiring:
   • The motor cannot be started normally or starting is difficult (may require manual turning to initiate).
   • The motor starts to shake and lacks power.
4. Risk of Damage: Using high voltage and high current for debugging with incorrect Hall wiring can damage the MOS tube on the controller board.

4. Operation

4.1 Speed Control (VR)

• Onboard Potentiometer: Adjust the potentiometer on the board to control the motor speed.
• External Signal: Connect an external 0-5V analog signal or a PWM signal to the VR input for speed control. The PWM signal should have an amplitude of 2.5V-5V and a frequency of 50 Hz - 20 kHz for best performance.

4.2 Direction Control (D/R)

• The D/R interface allows for positive and negative rotation control. Connect an external switch to this interface to toggle the motor's direction.

4.3 Brake Function

• The controller supports a brake function. When the D/R input is set to a high level (2.5V-5V), the brake is effective, providing strong braking force.

5. Maintenance

To ensure the longevity and reliable performance of your motor controller, follow these general maintenance guidelines:

• Keep Clean: Regularly clean the board to prevent dust and debris accumulation, which can affect performance and heat dissipation.
• Secure Connections: Periodically check all wiring connections to ensure they are tight and secure. Loose connections can lead to intermittent operation or damage.
• Environmental Conditions: Operate the controller within its specified temperature and humidity ranges. Avoid exposure to moisture, corrosive substances, or extreme temperatures.
• Heat Dissipation: Ensure adequate airflow around the controller, especially during high-power operation, to prevent overheating. The integrated heatsink helps, but additional cooling may be necessary in demanding applications.

6. Troubleshooting

If you encounter issues with your motor controller, refer to the following troubleshooting steps:

6.1 Common Issues and Solutions

• Motor Not Starting / Difficult Start / Shaking:
  • This is often due to incorrect Hall sensor wiring. Refer to Section 3.3 for debugging Hall lines. Ensure the +5V, GND, Ha, Hb, Hc lines are correctly identified and connected in the proper sequence.
  • Verify that the motor phase lines (MA, MB, MC) are correctly connected to the motor.
• No Power to Motor:
  • Check the main power supply (VCC, GND) for correct voltage (9-60V) and polarity.
  • Ensure all power connections are secure and free from shorts.
• Motor Runs Erratically or with Low Torque:
  • Re-check Hall sensor wiring as described above. Incorrect Hall signal sequencing can lead to unstable operation.
  • Verify that the speed control signal (VR) is stable and within the 0-5V range.
• Controller Overheating:
  • Ensure the motor's power requirements do not exceed the controller's maximum power (450W) or current (16A rated, 20A peak).
  • Check for any short circuits in the motor or wiring.
  • Ensure adequate ventilation around the controller.

6.2 Important Precautions

• No Fuse on Main Board: The power supply circuit on the main board does not have a built-in fuse. Any short circuit, even for a brief moment, can cause permanent damage to the chip. It is highly recommended to add an external fuse to the power input.
• Overcurrent Protection: The motor output has sampling overcurrent protection during normal operation. However, due to the high power and current capabilities of the module, avoid short circuits when the module is not operating normally, as this can burn the lines.
• Initial Testing: Always use small current and low voltage for initial wiring tests. Only proceed with high current and high voltage once you have confirmed correct wiring and normal operation.
• Insulation: This is a bare board module. Pay close attention to wiring insulation to prevent accidental contact between components or traces, especially with strong voltages.
• Motor Compatibility: Do not connect motors that are significantly inconsistent with the drive module's voltage and current ratings to avoid inexplicable damage.

7. User Tips

Based on common user experiences and best practices for motor controllers:

• Start Small: When first setting up, always begin with the lowest possible voltage and current to test connections. This minimizes the risk of damaging components if there's a wiring error.
• Double-Check Hall Sensors: The most frequent issue with BLDC motors is incorrect Hall sensor wiring. Take extra time to ensure these five wires are connected correctly and in the right sequence. If the motor stutters or fails to start, this is the first place to check.
• Heat Management: For continuous high-power applications, consider adding a small fan for active cooling, even with the integrated heatsink, to maintain optimal performance and extend the lifespan of the controller.
• External Potentiometer: If using an external potentiometer for speed control, ensure it is properly calibrated and connected to avoid erratic speed changes.
