1. What is the Omron Torque Formula?

The Omron torque formula calculates the torque (T) of a servo motor based on its power (P) and rotational speed (N). This is essential for selecting and sizing Omron servo motors for various industrial applications.

2. How Does the Calculator Work?

The calculator uses the Omron torque formula:

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

Where:

\( T \) — Torque in Newton-meters (Nm)
\( P \) — Power in kilowatts (kW)
\( N \) — Rotational speed in revolutions per minute (RPM)
9550 — Conversion factor combining unit conversions and constants

Explanation: The formula converts power and speed into the rotational force (torque) that the motor can produce. The constant 9550 comes from the conversion of units (kW to W, minutes to seconds) and the relationship between power and torque.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for selecting the right servo motor for an application, ensuring it can handle the required load without stalling or overheating.

4. Using the Calculator

Tips: Enter the motor's rated power in kW and its 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 combines the conversion factors for kW to W (1000), minutes to seconds (60), and the relationship between power and torque (2π/60 ≈ 0.10472).

Q2: Can I use this for non-Omron motors?
A: Yes, this formula is universal for calculating torque from power and speed, though specific motor characteristics may vary.

Q3: What if my power is in horsepower (HP)?
A: First convert HP to kW (1 HP ≈ 0.7457 kW) before using the calculator.

Q4: How does torque relate to motor performance?
A: Torque determines the motor's ability to overcome load resistance. Higher torque means better ability to handle heavy loads at a given speed.

Q5: What affects servo motor torque?
A: Torque depends on motor design, current, magnetic field strength, and cooling capacity. It typically decreases as speed increases.
