1. What is the Torque Formula?

The torque formula calculates rotational force from power and rotational speed. It's essential in mechanical engineering for designing and analyzing rotating machinery, engines, and motors.

2. How Does the Calculator Work?

The calculator uses the torque formula:

\[ T = \frac{P \times 9550}{N} \]

Where:

\( T \) — Torque (Newton-meters, Nm)
\( P \) — Power (kilowatts, kW)
\( N \) — Rotational speed (revolutions per minute, rpm)
9550 — Conversion constant (derived from unit conversions)

Explanation: The constant 9550 comes from converting between different units of power and rotational speed to maintain dimensional consistency.

3. Importance of Torque Calculation

Details: Torque calculation is crucial for mechanical design, motor selection, gearbox design, and ensuring proper operation of rotating equipment in various industrial applications.

4. Using the Calculator

Tips: Enter power in kilowatts (kW) and rotational speed in revolutions per minute (rpm). Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is the constant 9550 used?
A: The constant 9550 comes from unit conversions: 1 kW = 1000 N·m/s and 1 rpm = 1/60 revolutions per second, combined with the relationship between power, torque, and angular velocity.

Q2: Can I use different power units?
A: Yes, but you'll need to adjust the formula. For horsepower (HP), use T = (P × 5252) / N. The calculator currently supports kilowatts only.

Q3: What are typical torque values?
A: Torque values vary widely depending on application - from small motors with fractions of Nm to large industrial equipment with thousands of Nm.

Q4: How does torque relate to mechanical power?
A: Torque and rotational speed together determine mechanical power output. Higher torque at the same speed means more power, and vice versa.

Q5: When is this calculation most useful?
A: This calculation is essential for motor selection, gearbox design, conveyor systems, pumps, fans, and any application involving rotating machinery.
