1. What is the Torque Equation?

The torque equation calculates rotational force from power and rotational speed. It provides a fundamental relationship between these mechanical properties in rotating systems.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( T \) — Torque (Nm)
• \( P \) — Power (W)
• \( RPM \) — Rotations per minute (rev/min)
• \( \pi \) — Mathematical constant pi (approximately 3.1416)

Explanation: The equation converts power and rotational speed into the rotational force (torque) produced by a machine or engine.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for designing mechanical systems, selecting appropriate motors and drives, and ensuring proper performance of rotating machinery.

4. Using the Calculator

Tips: Enter power in watts, RPM in revolutions per minute. All values must be valid (power > 0, RPM > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why is the constant 60 used in the formula?
A: The constant 60 converts minutes to seconds since power is measured in watts (joules/second) while RPM is measured in revolutions per minute.

Q2: What are typical torque values for different applications?
A: Torque values vary widely depending on application - from small fractional Nm for precision instruments to thousands of Nm for industrial machinery.

Q3: Can this formula be used for both electric motors and engines?
A: Yes, this fundamental relationship applies to all rotating machinery regardless of the power source.

Q4: How does torque relate to mechanical work?
A: Torque represents the rotational equivalent of linear force. Work is done when torque causes rotation.

Q5: What factors affect torque output in real systems?
A: Efficiency losses, temperature, load conditions, and mechanical design all affect actual torque output in practical applications.
