How to Use Phoenix Edge 75 AMP ESC, 8S / 33.6V with 5 AMP BEC: Examples, Pinouts, and Specs

The Phoenix Edge 75 AMP ESC is a high-performance electronic speed controller (ESC) designed for demanding applications in RC vehicles, drones, and other motor-driven systems. Manufactured by Phoenix, this ESC is capable of handling up to 75 amps of continuous current and supports 8S lithium polymer (LiPo) batteries, providing a maximum input voltage of 33.6V. It also features an integrated 5 amp battery eliminator circuit (BEC), which can power servos, receivers, and other auxiliary devices without requiring a separate power source.

• RC airplanes, helicopters, and drones
• High-performance RC cars and boats
• Robotics and automation systems
• Custom motor control projects

1. Connect the Battery: Attach the LiPo battery to the ESC's battery input terminals, ensuring correct polarity.
2. Connect the Motor: Connect the three motor wires (A, B, C) to the brushless motor. If the motor spins in the wrong direction, swap any two wires.
3. Connect the Receiver: Plug the ESC's signal input connector into the throttle channel of your RC receiver.
4. Power On: Turn on the transmitter first, then connect the battery to the ESC. The ESC will initialize and emit a series of beeps to indicate readiness.
5. Calibrate Throttle: Follow the ESC's user manual to calibrate the throttle range for optimal performance.

• Battery Selection: Use only 2S to 8S LiPo batteries within the specified voltage range.
• Cooling: Ensure adequate airflow around the ESC to prevent overheating during operation.
• Wiring: Use appropriately rated wires and connectors to handle the high current.
• Programming: Use the Phoenix programming interface (if available) to customize settings such as throttle response, braking, and timing.

The Phoenix Edge ESC can be controlled using a PWM signal from an Arduino UNO. Below is an example code snippet to control the ESC:

#include <Servo.h> // Include the Servo library for PWM control

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 signal (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 signal to stop the motor
  delay(5000); // Wait for 5 seconds before repeating
}

Note: Ensure the ESC is properly calibrated before using it with an Arduino. Refer to the ESC's user manual for calibration instructions.

1. Motor Does Not Spin

   • Cause: Incorrect wiring or throttle signal not detected.
   • Solution: Verify motor connections (A, B, C) and ensure the ESC is receiving a valid PWM signal from the receiver or Arduino.

2. ESC Overheating

   • Cause: Insufficient cooling or excessive current draw.
   • Solution: Improve airflow around the ESC and ensure the motor and propeller are not overloading the system.

3. Beeping Sounds

   • Cause: Low battery voltage or throttle signal not detected.
   • Solution: Check the battery voltage and ensure the transmitter is powered on and bound to the receiver.

4. Motor Spins in the Wrong Direction

   • Cause: Incorrect motor wiring.
   • Solution: Swap any two of the three motor wires (A, B, C) to reverse the direction.

• Q: Can I use this ESC with a brushed motor?
  A: No, the Phoenix Edge 75 AMP ESC is designed specifically for brushless motors.

• Q: How do I program the ESC?
  A: Use the Phoenix programming interface or follow the manual's instructions for programming via the transmitter.

• Q: What happens if I exceed the 75A current limit?
  A: The ESC's overcurrent protection will activate, shutting down the motor to prevent damage.

• Q: Can I use this ESC with a 12V lead-acid battery?
  A: No, this ESC is designed for use with 2S to 8S LiPo batteries only.
