1. What is the Torque Formula?

The torque formula relates mechanical power to rotational speed. It's essential for understanding motor performance and selecting appropriate motors for specific applications.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( \tau \) — Torque (N·m)
• \( P \) — Power (W)
• \( f \) — Frequency (Hz)
• \( \pi \) — Pi constant (~3.14159)

Explanation: The formula shows that torque is inversely proportional to frequency (rotational speed) when power is constant.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for motor selection, mechanical design, and ensuring systems operate within safe parameters.

4. Using the Calculator

Tips: Enter power in watts and frequency in hertz. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the relationship between torque and speed?
A: For constant power, torque decreases as speed increases, and vice versa.

Q2: How does this apply to electric motors?
A: Motors typically produce maximum torque at low speeds and less torque at higher speeds for a given power input.

Q3: What if I know RPM instead of Hz?
A: Convert RPM to Hz by dividing by 60 (1 Hz = 60 RPM).

Q4: Does this formula account for efficiency losses?
A: No, this calculates theoretical torque. Actual torque may be lower due to efficiency losses.

Q5: Can I use this for gear systems?
A: This calculates torque at the motor shaft. Gear ratios will modify the output torque and speed.
