1. What is Servo Motor Torque?

Servo motor torque is the rotational force produced by a servo motor, calculated as the product of the applied force and the distance from the pivot point (radius). It determines the motor's ability to overcome load resistance and perform mechanical work.

2. How Does the Calculator Work?

The calculator uses the fundamental torque formula:

Where:

• \( Torque \) — Rotational force in Newton-meters (N·m)
• \( Force \) — Applied force in Newtons (N)
• \( Radius \) — Distance from pivot point in meters (m)

Explanation: This formula calculates the torque required for a servo motor to lift or move a load at a specific distance from the rotational axis.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for selecting the appropriate servo motor for applications, ensuring it can handle the required load without stalling or overheating, and optimizing system performance.

4. Using the Calculator

Tips: Enter force in Newtons and radius in meters. Ensure both values are positive numbers. The calculator will compute the torque in Newton-meters required for your servo motor application.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between static and dynamic torque?
A: Static torque is the torque required to hold a load in position, while dynamic torque is needed to accelerate or move a load. Servo motors must be sized for both requirements.

Q2: How do I convert torque from N·m to other units?
A: Common conversions: 1 N·m = 8.8507 lb·in, 1 N·m = 0.7376 lb·ft, 1 N·m = 10.1972 kg·cm.

Q3: What safety factor should I use for servo motor selection?
A: Typically, a safety factor of 1.5-2.0 is recommended to account for friction, inefficiencies, and unexpected load variations.

Q4: How does gear reduction affect torque?
A: Gear reduction increases output torque while decreasing speed. The torque multiplication equals the gear ratio (e.g., 10:1 gear ratio multiplies torque by 10).

Q5: What are common torque requirements for different applications?
A: Small robotics: 0.1-2 N·m, CNC machines: 5-50 N·m, industrial automation: 10-200 N·m, heavy machinery: 200+ N·m.
