1. What is Servo Motor Torque?

Torque in servo motors is the rotational force produced by the motor shaft. It's a crucial parameter for determining the motor's ability to perform work and overcome resistance in mechanical systems.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( T \) — Torque (Nm)
• \( P \) — Power (kW)
• \( N \) — Speed (RPM)
• 9550 — Conversion constant (derived from unit conversions)

Explanation: The equation shows that torque is inversely proportional to speed when power is constant. Higher speed means lower torque output for the same power.

3. Importance of Torque Calculation

Details: Proper torque calculation ensures the servo motor can handle the required load without stalling or overheating. It's essential for system design, motor selection, and performance optimization.

4. Using the Calculator

Tips: Enter power in kilowatts (kW) and speed in revolutions per minute (RPM). Both values must be positive numbers. The calculator will output torque in Newton-meters (Nm).

5. Frequently Asked Questions (FAQ)

Q1: Why is 9550 used in the formula?
A: 9550 is a conversion factor derived from unit conversions (1 kW = 1000 W, 1 Nm/s = 1 W, 1 RPM = 2π/60 rad/s).

Q2: What's the difference between rated torque and peak torque?
A: Rated torque is the continuous torque a motor can produce without overheating, while peak torque is the maximum short-term torque capability.

Q3: How does voltage affect servo motor torque?
A: Higher voltage typically allows higher torque output, but must stay within motor specifications to avoid damage.

Q4: What if my motor power is in horsepower (HP)?
A: Convert HP to kW first (1 HP ≈ 0.7457 kW) before using this calculator.

Q5: How important is torque for servo motor selection?
A: Critical - the motor must provide enough torque to overcome the load inertia and friction with sufficient margin.
