1. What Is Torque?

Torque is a measure of the rotational force applied to an object. In motor applications, it represents the turning force that the motor can generate. Torque is crucial for understanding a motor's ability to perform work and overcome resistance.

2. How Does The Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque in Newton-meters (N·m)
• \( P \) — Power in watts (W)
• \( \omega \) — Angular speed in radians per second (rad/s)

Explanation: This formula shows the direct relationship between power, angular speed, and torque. Higher power or lower speed results in greater torque output.

3. Importance Of Torque Calculation

Details: Accurate torque calculation is essential for motor selection, mechanical design, and ensuring proper performance in applications such as robotics, automotive systems, industrial machinery, and power tools.

4. Using The Calculator

Tips: Enter power in watts and angular speed in radians per second. Both values must be positive numbers. For RPM to rad/s conversion, multiply RPM by 0.10472.

5. Frequently Asked Questions (FAQ)

Q1: What Is The Difference Between Torque And Power?
A: Torque is the rotational force, while power is the rate at which work is done. Power = Torque × Angular Speed.

Q2: How Do I Convert RPM To Rad/s?
A: Multiply RPM by 0.10472 to get rad/s. For example, 1000 RPM = 1000 × 0.10472 = 104.72 rad/s.

Q3: What Are Typical Torque Values For Electric Motors?
A: Small motors may produce 0.1-1 N·m, while industrial motors can generate hundreds or thousands of N·m depending on size and application.

Q4: Why Is Torque Important In Motor Selection?
A: Torque determines a motor's ability to start, accelerate, and maintain motion under load. Insufficient torque can cause stalling or poor performance.

Q5: How Does Gear Reduction Affect Torque?
A: Gear reduction increases output torque while decreasing speed, maintaining the same power output (minus efficiency losses).
