How to Use Motor 3600 1800kv: Examples, Pinouts, and Specs

The Motor 3600 1800kv is a high-performance brushless motor designed for applications requiring high speed, efficiency, and reliability. Manufactured by Motor, this motor is ideal for use in drones, RC vehicles, and other high-speed applications. Its KV rating of 1800 indicates that it spins at 1800 revolutions per minute (RPM) per volt applied, making it suitable for projects demanding precision and power.

• Drones and quadcopters
• Remote-controlled (RC) cars, boats, and planes
• Robotics requiring high-speed motors
• DIY projects involving high-efficiency brushless motors

Below are the key technical details for the Motor 3600 1800kv:

The Motor 3600 1800kv has three wires for connection to an electronic speed controller (ESC). These wires are color-coded for easy identification:

Note: The motor does not have a built-in sensor, so it operates as a sensorless brushless motor.

1. Connect to an ESC: The motor must be connected to an electronic speed controller (ESC) that matches its voltage and current ratings. Use the 3.5mm bullet connectors to attach the motor wires to the ESC outputs (A, B, and C).
2. Power Supply: Use a LiPo battery within the operating voltage range (7.4V to 22.2V). Ensure the battery can supply sufficient current (at least 35A) for optimal performance.
3. Control Signal: The ESC should be connected to a microcontroller (e.g., Arduino UNO) or RC receiver to provide the PWM signal for speed control.
4. Mounting: Secure the motor using the mounting holes (16mm x 19mm pattern) and ensure proper alignment to avoid vibrations.
5. Propeller Installation: If using the motor for drones or RC planes, attach a compatible propeller to the motor shaft. Ensure the propeller is balanced to prevent damage.

• Cooling: Ensure adequate airflow around the motor to prevent overheating during operation.
• ESC Compatibility: Use an ESC that supports sensorless brushless motors and matches the motor's current and voltage ratings.
• Reverse Direction: To reverse the motor's rotation, swap any two of the three motor wires connected to the ESC.
• Safety: Always disconnect the power supply when making adjustments to the motor or ESC.

Below is an example of controlling the motor using an Arduino UNO and an ESC:

// Example code to control Motor 3600 1800kv using Arduino UNO and ESC
#include <Servo.h> // Include Servo library to generate PWM signal

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

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

void loop() {
  esc.writeMicroseconds(1500); // Set throttle to 50% (adjust value as needed)
  delay(5000); // Run motor for 5 seconds

  esc.writeMicroseconds(1000); // Stop the motor
  delay(2000); // Wait for 2 seconds before restarting
}

Note: Ensure the ESC is properly armed before running the motor. Refer to the ESC's manual for specific arming procedures.

1. Motor Does Not Spin

   • Cause: Incorrect wiring or ESC not armed.
   • Solution: Verify the motor wires are correctly connected to the ESC. Ensure the ESC is armed and receiving a valid PWM signal.

2. Motor Spins in the Wrong Direction

   • Cause: Incorrect phase wire connections.
   • Solution: Swap any two of the three motor wires connected to the ESC.

3. Motor Overheats

   • Cause: Insufficient cooling or overloading.
   • Solution: Ensure proper airflow around the motor and avoid exceeding the maximum current rating (35A).

4. Vibrations During Operation

   • Cause: Unbalanced propeller or improper mounting.
   • Solution: Balance the propeller and ensure the motor is securely mounted.

• Q: Can this motor be used with a 3S LiPo battery?

  • A: Yes, the motor supports 3S LiPo batteries (11.1V) within its operating voltage range.

• Q: Is this motor waterproof?

  • A: No, the motor is not waterproof. Avoid exposing it to water or moisture.

• Q: What is the maximum propeller size for this motor?

  • A: The maximum propeller size depends on the application and power requirements. Refer to the ESC and propeller manufacturer's recommendations.

• Q: Can I use this motor with a brushed ESC?

  • A: No, this motor requires a brushless ESC for proper operation.
