1. What is Torque?

Torque is a measure of the rotational force applied to an object. It is a crucial parameter in mechanical engineering, automotive applications, and various industrial processes where rotational motion is involved.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (Nm)
• \( P \) — Power (W)
• \( RPM \) — Rotations per minute (rev/min)
• \( \pi \) — Mathematical constant pi (approximately 3.14159)

Explanation: This formula calculates the torque produced by a rotating system based on the power input and rotational 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 revolutions per minute (RPM). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

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

Q2: Can I use different power units?
A: Yes, but you'll need to convert them to watts first. 1 horsepower = 745.7 watts, 1 kilowatt = 1000 watts.

Q3: What is a typical torque range for electric motors?
A: Torque varies greatly by motor size and type, ranging from less than 1 Nm for small motors to thousands of Nm for large industrial motors.

Q4: How does torque relate to horsepower?
A: Horsepower is a measure of power, while torque is a measure of rotational force. They are related through the formula: HP = (Torque × RPM) / 5252.

Q5: Why is the constant 60 used in the formula?
A: The constant 60 converts minutes to seconds, as power is measured in watts (joules per second) while RPM is in revolutions per minute.
