How to Use AM32 esc brushless 60 amp: Examples, Pinouts, and Specs

The AM32 ESC (Electronic Speed Controller) is a high-performance controller designed for brushless motors, capable of delivering up to 60 amps of continuous current. It is widely used in applications requiring precise motor control, such as remote-controlled (RC) vehicles, drones, and robotics. The AM32 ESC ensures smooth motor operation, efficient power management, and reliable performance under demanding conditions.

• RC cars, boats, and airplanes
• Multirotor drones and quadcopters
• Robotics and automation systems
• Electric skateboards and scooters

The AM32 ESC is engineered to provide robust and efficient motor control. Below are its key technical details:

The AM32 ESC typically has the following pin connections:

1. Connect the Power Supply:
   • Attach the positive and negative terminals of a compatible LiPo battery (2S–6S) to the ESC's power input pins.
2. Connect the Motor:
   • Connect the three motor wires to the ESC's motor phase outputs (A, B, C). The order does not matter initially; you can swap two wires if the motor spins in the wrong direction.
3. Connect the Signal Input:
   • Connect the signal input pin to the PWM, DShot, or Multishot output of your flight controller or receiver.
   • Ensure the ground (GND) pin is also connected to the flight controller or receiver's ground.
4. Calibrate the ESC (if required):
   • Follow the calibration procedure specific to your transmitter and receiver to ensure proper throttle range.
5. Secure the ESC:
   • Mount the ESC securely in your vehicle or drone, ensuring adequate airflow for cooling.

• Cooling: Ensure proper ventilation or cooling to prevent overheating during operation.
• Voltage Compatibility: Use a battery within the specified voltage range (2S–6S LiPo).
• Signal Type: Verify that your flight controller or receiver supports the signal type (PWM, DShot, or Multishot) used by the ESC.
• Firmware Updates: The AM32 firmware is open-source and can be updated for improved performance or additional features.

If you are using the AM32 ESC with an Arduino UNO to control a brushless motor via PWM, the following code demonstrates how to send a PWM signal:

#include <Servo.h> // Include the Servo library for generating 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 (1000 µs)
  delay(2000); // Wait for 2 seconds to allow the ESC to initialize
}

void loop() {
  esc.writeMicroseconds(1500); // Send a mid-throttle signal (1500 µs)
  delay(5000); // Run the motor at mid-throttle for 5 seconds

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

Note:

• Ensure the ESC is properly calibrated before running the code.
• The writeMicroseconds() function sends a PWM signal in microseconds, where 1000 µs is typically the minimum throttle, and 2000 µs is the maximum throttle.

1. Motor Does Not Spin:

   • Cause: Incorrect wiring or signal input.
   • Solution: Verify all connections, ensure the ESC is receiving a valid signal, and check the throttle calibration.

2. Motor Spins in the Wrong Direction:

   • Cause: Motor phase wires are connected in the wrong order.
   • Solution: Swap any two of the three motor wires to reverse the direction.

3. ESC Overheats:

   • Cause: Insufficient cooling or excessive current draw.
   • Solution: Improve airflow around the ESC or reduce the motor load.

4. No Response from ESC:

   • Cause: Incorrect signal type or firmware issue.
   • Solution: Ensure the signal type matches the ESC's configuration and update the firmware if necessary.

• Can I use the AM32 ESC with a brushed motor?

  • No, the AM32 ESC is designed specifically for brushless motors.

• What happens if I exceed the 60A current rating?

  • Exceeding the current rating may cause the ESC to overheat or fail. Use a motor and propeller combination that stays within the rated current.

• How do I update the AM32 firmware?

  • Firmware updates can be performed using a compatible programming tool and software. Refer to the AM32 firmware documentation for detailed instructions.

• Is a BEC included in the AM32 ESC?

  • No, the AM32 ESC does not include a BEC. You will need an external BEC or a separate power source for your receiver or flight controller.

By following this documentation, you can effectively integrate and operate the AM32 ESC in your projects.
