1. What is Torque?

Torque is a measure of the rotational force applied to an object. In electric motors, torque determines the motor's ability to perform work and overcome resistance to rotation.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( T \) — Torque (Newton-meters, Nm)
• \( F \) — Force applied (Newtons, N)
• \( r \) — Distance from pivot point (meters, m)

Explanation: The torque increases with either greater force or greater distance from the pivot point (lever arm).

3. Importance of Torque Calculation

Details: Torque calculation is essential for motor selection, mechanical design, and ensuring proper operation of rotating machinery. It helps determine if a motor can handle the required load.

4. Using the Calculator

Tips: Enter force in Newtons and distance in meters. Both values must be positive numbers. The calculator will compute the torque in Newton-meters (Nm).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between torque and power?
A: Torque is rotational force, while power is the rate of doing work (torque × angular velocity). Power determines how fast work can be done, torque determines the force available.

Q2: How does distance affect torque?
A: Torque increases linearly with distance from the pivot point. Doubling the lever arm doubles the torque for the same force.

Q3: What are typical torque values for electric motors?
A: Small motors might produce 0.1-1 Nm, while industrial motors can produce hundreds or thousands of Nm, depending on size and design.

Q4: How is torque related to motor speed?
A: Generally, motors produce maximum torque at low speeds, with torque decreasing as speed increases (for most AC and DC motors).

Q5: Can I use this for gear systems?
A: This calculates input torque. For gear systems, you'll need to account for gear ratios which multiply torque while reducing speed.
