1. What is the Torque Calculation Formula?

The torque calculation formula \( T = \frac{P \times 60}{2\pi N} \) calculates torque from power and rotational speed. This formula is essential in mechanical engineering for determining the rotational force produced by motors and engines.

2. How Does the Calculator Work?

The calculator uses the torque formula:

\[ T = \frac{P \times 60}{2\pi N} \]

Where:

Explanation: The formula converts power and rotational speed into torque, accounting for the conversion between angular velocity and linear power.

3. Importance of Torque Calculation

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

4. Using the Calculator

Tips: Enter power in watts and rotational speed in RPM. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is 60 in the numerator of the formula?
A: The factor of 60 converts revolutions per minute (RPM) to revolutions per second, as power is measured in watts (joules per second).

Q2: What are typical torque values for electric motors?
A: Torque values vary widely based on motor size and type, ranging from less than 1 Nm for small motors to hundreds of Nm for industrial motors.

Q3: Can this formula be used for any rotating system?
A: Yes, this formula applies to any system where power and rotational speed are known, including engines, motors, and turbines.

Q4: How does torque relate to mechanical power?
A: Torque and rotational speed together determine mechanical power output. Higher torque at the same RPM results in higher power output.

Q5: What units should I use for accurate results?
A: For this calculator, use watts for power and RPM for rotational speed. The result will be in Newton-meters (Nm).
