How to Use ESC 60A: Examples, Pinouts, and Specs

The ESC 60A by BelHelix is a high-performance Electronic Speed Controller designed to manage the speed, direction, and throttle of brushless motors. With a current rating of 60 Amperes, this ESC is ideal for applications requiring precise motor control, such as remote-controlled (RC) vehicles, drones, boats, and other robotics projects. Its robust design ensures reliable operation under demanding conditions, making it a popular choice for hobbyists and professionals alike.

• RC cars, boats, and airplanes
• Drones and quadcopters
• Robotics and automation projects
• Electric skateboards and scooters

Below are the key technical details for the ESC 60A:

The ESC 60A has the following connections:

1. Connect the Power Supply:

   • Attach the red wire to the positive terminal of your LiPo battery.
   • Attach the black wire to the negative terminal of your LiPo battery.
   • Ensure the battery voltage is within the supported range (7.4V–22.2V).

2. Connect the Motor:

   • Connect the three motor output wires (A, B, C) to the brushless motor.
   • If the motor spins in the wrong direction, swap any two of the motor wires.

3. Connect the Signal Input:

   • Connect the white signal wire to the PWM output of your RC receiver or flight controller.
   • Connect the black ground wire to the ground of your RC receiver or flight controller.

4. Power On:

   • Turn on the power supply. The ESC will emit a series of beeps to indicate initialization.
   • The number of beeps corresponds to the number of LiPo cells detected.

5. Throttle Calibration (Optional):

   • Set the throttle stick on your transmitter to maximum.
   • Power on the ESC and wait for a confirmation beep.
   • Move the throttle stick to the minimum position and wait for another confirmation beep.
   • The ESC is now calibrated.

• Cooling: Ensure adequate airflow or cooling to prevent overheating during operation.
• Battery Compatibility: Use only LiPo batteries within the specified voltage range.
• Signal Quality: Use a clean and stable PWM signal for optimal performance.
• Wiring: Double-check all connections before powering on to avoid short circuits or damage.
• Mounting: Secure the ESC in a vibration-free location to prevent damage during operation.

The ESC 60A can be controlled using an Arduino UNO by generating a PWM signal. Below is an example code snippet:

#include <Servo.h> // Include the Servo library to generate PWM signals

Servo esc; // Create a Servo object to control the ESC

void setup() {
  esc.attach(9); // Attach the ESC signal wire to pin 9 on the Arduino
  esc.writeMicroseconds(1000); // Send minimum throttle (1ms pulse)
  delay(2000); // Wait for the ESC to initialize
}

void loop() {
  esc.writeMicroseconds(1500); // Send mid-throttle (1.5ms pulse)
  delay(5000); // Run the motor at mid-speed for 5 seconds

  esc.writeMicroseconds(2000); // Send maximum throttle (2ms pulse)
  delay(5000); // Run the motor at full speed for 5 seconds

  esc.writeMicroseconds(1000); // Send minimum throttle to stop the motor
  delay(5000); // Wait for 5 seconds before repeating
}

• Ensure the ESC is properly calibrated before running the code.
• Always test the setup without a propeller attached to the motor for safety.

1. Motor Does Not Spin:

   • Check all connections, especially the signal wire.
   • Ensure the battery is charged and within the supported voltage range.
   • Verify that the ESC is receiving a valid PWM signal.

2. Motor Spins in the Wrong Direction:

   • Swap any two of the motor output wires (A, B, or C).

3. ESC Overheats:

   • Ensure proper cooling and avoid exceeding the continuous current rating.
   • Check for obstructions in the airflow or excessive load on the motor.

4. ESC Beeps Continuously:

   • This indicates a low-voltage or signal error. Verify the battery voltage and signal connection.

5. Throttle Calibration Fails:

   • Ensure the transmitter is set to the correct throttle range.
   • Repeat the calibration process carefully.

• Can I use the ESC 60A with a brushed motor? No, this ESC is designed specifically for brushless motors.

• What happens if I exceed the peak current rating? The ESC may shut down temporarily to protect itself or could be permanently damaged. Always stay within the specified ratings.

• Can I power my Arduino directly from the ESC's BEC output? Yes, the 5V/3A BEC output can power an Arduino or other low-power devices.

• How do I update the firmware on the ESC? Firmware updates are not supported for this model.
