How to Use Driver Motor DC Brushless 36V: Examples, Pinouts, and Specs

The Driver Motor DC Brushless 36V is a high-performance motor driver designed to control the speed and direction of 36V brushless DC (BLDC) motors. Manufactured by Driver Motor with the part ID DC 36V, this driver ensures efficient operation and precise control, making it ideal for a wide range of applications. It is commonly used in robotics, electric vehicles, industrial automation, and other systems requiring reliable motor control.

• Electric scooters and bicycles
• Robotics and automation systems
• Conveyor belts and industrial machinery
• Fans, pumps, and HVAC systems
• DIY projects involving BLDC motors

The following table outlines the key technical details of the Driver Motor DC Brushless 36V:

The Driver Motor DC Brushless 36V features the following pin configuration:

1. Power Supply: Connect a 36V DC power supply to the VCC and GND pins of the driver.
2. Motor Connection: Connect the BLDC motor's U, V, and W terminals to the corresponding U, V, and W pins on the driver.
3. Control Signals:
   • Connect a PWM signal (0-5V) to the PWM pin for speed control.
   • Use the DIR pin to set the motor's direction (HIGH for forward, LOW for reverse).
   • Use the EN pin to enable or disable the driver (HIGH to enable, LOW to disable).
4. Feedback: If needed, connect the FG pin to a microcontroller or monitoring system to receive motor speed feedback.

• Ensure the power supply voltage is stable and within the specified range (36V DC).
• Use appropriate heat dissipation methods (e.g., heatsinks) if the driver operates at high currents for extended periods.
• Avoid reversing the polarity of the power supply to prevent damage to the driver.
• Use a properly rated BLDC motor that matches the driver's specifications.
• For PWM control, ensure the signal frequency is within the recommended range (typically 1kHz to 20kHz).

The Driver Motor DC Brushless 36V can be easily controlled using an Arduino UNO. Below is an example code snippet for controlling motor speed and direction:

// Define pin connections
const int pwmPin = 9;  // PWM signal for speed control
const int dirPin = 8;  // Direction control
const int enPin = 7;   // Enable pin

void setup() {
  // Set pin modes
  pinMode(pwmPin, OUTPUT);
  pinMode(dirPin, OUTPUT);
  pinMode(enPin, OUTPUT);

  // Enable the motor driver
  digitalWrite(enPin, HIGH);
}

void loop() {
  // Set motor direction to forward
  digitalWrite(dirPin, HIGH);

  // Gradually increase motor speed
  for (int speed = 0; speed <= 255; speed++) {
    analogWrite(pwmPin, speed);  // Set PWM duty cycle (0-255)
    delay(20);                   // Wait 20ms
  }

  // Gradually decrease motor speed
  for (int speed = 255; speed >= 0; speed--) {
    analogWrite(pwmPin, speed);
    delay(20);
  }

  // Set motor direction to reverse
  digitalWrite(dirPin, LOW);

  // Repeat the speed ramp-up and ramp-down
  for (int speed = 0; speed <= 255; speed++) {
    analogWrite(pwmPin, speed);
    delay(20);
  }
  for (int speed = 255; speed >= 0; speed--) {
    analogWrite(pwmPin, speed);
    delay(20);
  }
}

1. Motor Does Not Spin:

   • Check the power supply voltage and ensure it is 36V DC.
   • Verify that the EN pin is set to HIGH to enable the driver.
   • Ensure the motor is properly connected to the U, V, and W pins.

2. Motor Spins in the Wrong Direction:

   • Check the logic level of the DIR pin. Set it to HIGH for forward and LOW for reverse.
   • Verify the motor's wiring to ensure the U, V, and W connections are correct.

3. Motor Speed is Unstable:

   • Ensure the PWM signal is clean and within the recommended frequency range.
   • Check for loose connections or faulty wiring.

4. Driver Overheats:

   • Ensure the current drawn by the motor does not exceed the driver's maximum rating (15A).
   • Use a heatsink or active cooling to dissipate heat.

Q: Can I use this driver with a 24V BLDC motor?
A: No, this driver is specifically designed for 36V BLDC motors. Using it with a lower voltage motor may result in suboptimal performance or damage.

Q: What is the recommended PWM frequency for speed control?
A: The recommended PWM frequency is between 1kHz and 20kHz for optimal performance.

Q: Can I use this driver with a brushed DC motor?
A: No, this driver is designed exclusively for brushless DC motors and is not compatible with brushed motors.

Q: How can I monitor the motor's speed?
A: Connect the FG pin to a microcontroller or frequency counter to measure the feedback signal, which corresponds to the motor's speed.
