1. What is Motor Torque?

Torque is a rotational force produced by an electric motor. It's a crucial parameter in motor selection and application, determining the motor's ability to perform work. The Omron motor torque calculation helps in selecting the right motor for specific applications.

2. How Does the Calculator Work?

The calculator uses the torque equation:

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

Where:

\( T \) — Torque in Newton-meters (Nm)
\( P \) — Power in kilowatts (kW)
\( N \) — Speed in revolutions per minute (RPM)
9550 — Conversion factor (derived from unit conversions)

Explanation: The equation shows that torque is directly proportional to power and inversely proportional to speed. The constant 9550 comes from the conversion of units (kW to W and minutes to seconds).

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for proper motor selection, ensuring the motor can handle the required mechanical load without stalling or overheating.

4. Using the Calculator

Tips: Enter power in kW and speed in RPM. Both values must be positive numbers. The calculator will compute the torque in Nm.

5. Frequently Asked Questions (FAQ)

Q1: Why is 9550 used in the formula?
A: 9550 is a conversion factor derived from (60 seconds/minute × 1000 watts/kW) / (2π radians/revolution), simplified for practical use.

Q2: What are typical torque values for Omron motors?
A: Torque values vary by motor size and type. Small servo motors might produce 0.1-5 Nm, while larger industrial motors can produce hundreds of Nm.

Q3: How does torque relate to motor performance?
A: Torque determines the motor's ability to overcome load resistance. Higher torque means better ability to start under load and handle sudden load changes.

Q4: What if my motor power is in horsepower (HP)?
A: First convert HP to kW (1 HP ≈ 0.746 kW) before using this calculator.

Q5: Does this formula work for all motor types?
A: This is a general formula for rotational mechanical power. Specific motor types (servo, stepper, induction) may have additional torque characteristics.
