1. What is the Torque Formula?

The torque formula T = P/ω calculates motor torque from power and angular velocity. It represents the rotational force produced by a motor, which is essential for understanding motor performance and mechanical system design.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (Nm)
• \( P \) — Power (W)
• \( \omega \) — Angular velocity (rad/s)

Explanation: This formula shows the direct relationship between power and torque, where torque decreases as angular velocity increases for a constant power output.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for motor selection, mechanical system design, performance analysis, and ensuring proper operation of rotating machinery.

4. Using the Calculator

Tips: Enter power in watts and angular velocity in radians per second. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for this calculation?
A: Power should be in watts (W) and angular velocity in radians per second (rad/s) for torque in newton-meters (Nm).

Q2: How do I convert RPM to rad/s?
A: Multiply RPM by π/30 (approximately 0.10472) to convert to rad/s.

Q3: Can I use horsepower instead of watts?
A: Yes, but you must convert horsepower to watts first (1 hp = 745.7 W).

Q4: What is typical torque range for electric motors?
A: Torque varies greatly by motor type and size, ranging from fractional Nm for small motors to thousands of Nm for large industrial motors.

Q5: Does this formula work for all motor types?
A: This fundamental relationship applies to all rotating machinery, though specific motor characteristics may affect actual performance.
