1. What is Torque?

Torque is a measure of the rotational force applied to an object. In motors, torque represents the twisting force that causes rotation and is a crucial parameter for determining the motor's ability to perform work.

2. How Does the Calculator Work?

The calculator uses the torque formula:

\[ \tau = F \times r \]

Where:

Explanation: The torque is calculated by multiplying the applied force by the perpendicular distance from the axis of rotation to the line of action of the force.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for motor selection, mechanical design, and ensuring proper operation of rotating machinery. It helps determine if a motor can provide sufficient rotational force for a specific application.

4. Using the Calculator

Tips: Enter force in Newtons and radius in meters. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What units are used for torque?
A: Torque is typically measured in Newton-meters (N·m) in the SI system, or pound-feet (lb·ft) in the imperial system.

Q2: How does torque relate to motor power?
A: Power (in watts) equals torque (in N·m) multiplied by angular velocity (in radians per second). Higher torque at the same speed means more power.

Q3: What affects the torque output of a motor?
A: Motor design, electrical characteristics, magnetic field strength, and current supply all affect the torque output of an electric motor.

Q4: What is the difference between starting torque and running torque?
A: Starting torque is the torque produced at zero speed when the motor is initially energized, while running torque is the torque produced during normal operation at various speeds.

Q5: Why is torque important in motor applications?
A: Torque determines a motor's ability to overcome load resistance, accelerate loads, and maintain rotation under varying operating conditions.
