1. What is a Torque Speed Power Calculator?

Definition: This calculator determines the mechanical power output based on torque and angular speed using the fundamental relationship between these quantities.

Purpose: It helps engineers, mechanics, and students calculate power in rotational systems, essential for designing and analyzing motors, engines, and mechanical drives.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Power (Watts, W)
• \( \tau \) — Torque (Newton meters, N·m)
• \( \omega \) — Angular speed (radians per second, rad/s)

Explanation: Power in rotational systems is the product of torque and angular velocity. This relationship is fundamental in mechanical engineering.

3. Importance of Torque-Speed-Power Calculation

Details: Understanding this relationship is crucial for selecting motors, designing transmissions, and analyzing mechanical system performance.

4. Using the Calculator

Tips: Enter the torque in Newton-meters and angular speed in radians per second. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert RPM to rad/s?
A: Multiply RPM by 0.10472 (since 1 RPM = 2π/60 ≈ 0.10472 rad/s).

Q2: What's the difference between torque and power?
A: Torque is rotational force, while power is the rate of doing work (torque × speed).

Q3: Can I calculate torque if I know power and speed?
A: Yes, rearrange the formula: τ = P/ω.

Q4: What are typical torque values for electric motors?
A: Small motors might produce 0.1-1 N·m, while industrial motors can produce hundreds of N·m.

Q5: How does this relate to horsepower?
A: 1 horsepower ≈ 745.7 Watts. Convert Watts to HP by dividing by 745.7.
