1. What is Drone Motor Torque?

Torque is the rotational force produced by a drone motor. It determines how effectively the motor can turn the propeller against air resistance and is crucial for drone performance, especially during acceleration and maneuvering.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( Power \) — Electrical power input to the motor (Watts)
• \( RPM \) — Rotations per minute of the motor
• \( 2\pi \) — Conversion factor from radians to revolutions
• \( \frac{RPM}{60} \) — Converts RPM to revolutions per second

Explanation: The equation calculates the torque output based on the power input and rotational speed of the motor.

3. Importance of Torque Calculation

Details: Proper torque calculation helps in selecting the right motor for your drone, ensuring adequate thrust for takeoff, maneuverability, and payload capacity.

4. Using the Calculator

Tips: Enter motor power in Watts and RPM from motor specifications. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a good torque value for drone motors?
A: Ideal torque depends on drone size and purpose. Racing drones need high torque for quick acceleration, while photography drones prioritize efficiency.

Q2: How does torque relate to thrust?
A: Torque combined with propeller characteristics determines thrust. Higher torque allows for larger or higher-pitch propellers.

Q3: Why does torque decrease as RPM increases?
A: For a given power input, torque must decrease as speed increases because power is the product of torque and angular velocity.

Q4: How can I increase my drone's torque?
A: Use motors with lower KV ratings, higher voltage batteries, or propellers with less pitch to allow the motor to operate at higher torque.

Q5: Does this calculation account for motor efficiency?
A: No, this is the theoretical torque based on electrical input power. Actual torque will be lower due to motor inefficiencies.
