Definition: This calculator converts torque (rotational force) and angular velocity to mechanical power in watts.
Purpose: It helps engineers and technicians determine the power output or requirement of rotating machinery.
The calculator uses the formula:
Where:
Explanation: Power is the product of torque and angular velocity, representing the rate at which work is done in a rotational system.
Details: Accurate power calculation is essential for motor selection, mechanical design, and energy efficiency analysis in rotating systems.
Tips: Enter torque in Newton-meters and angular velocity in radians per second. Both values must be positive numbers.
Q1: How do I convert RPM to rad/s?
A: Multiply RPM by 0.10472 (2π/60) to get rad/s.
Q2: What's the difference between torque and power?
A: Torque is rotational force, while power is the rate of doing work (force × speed).
Q3: Can I use this for electric motors?
A: Yes, this applies to any rotating system including electric motors.
Q4: What if I know power and need torque?
A: Rearrange the formula: \( T = \frac{P}{\omega} \)
Q5: What are typical torque values?
A: Small motors: 0.1-10 Nm, car engines: 100-500 Nm, industrial motors: up to several thousand Nm.
