1. What is the Torque Formula?

The torque formula calculates the rotational force produced by a machine based on power input and rotational speed. It's a fundamental equation in mechanical engineering and physics.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (N·m)
• \( P \) — Power (W)
• \( N \) — Rotational speed (RPM)
• \( \pi \) — Mathematical constant pi (approximately 3.1416)

Explanation: The formula converts rotational speed from RPM to radians per second and calculates the torque required to produce the given power at that speed.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for designing mechanical systems, selecting appropriate motors and gearboxes, and ensuring proper operation of rotating machinery.

4. Using the Calculator

Tips: Enter power in watts (W) and rotational speed in RPM (revolutions per minute). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for power and speed?
A: Power should be in watts (W) and rotational speed in RPM (revolutions per minute) for this calculator.

Q2: Can I use different power units?
A: Yes, but you'll need to convert to watts first (1 kW = 1000 W, 1 HP ≈ 745.7 W).

Q3: What is the significance of the constant 60 in the formula?
A: The constant 60 converts RPM to revolutions per second, which is then converted to radians per second using the 2π factor.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise for the given inputs, assuming ideal conditions without mechanical losses.

Q5: Can this formula be used for electric motors?
A: Yes, this formula is commonly used to calculate the torque output of electric motors based on their power rating and operating speed.
