1. What Is Motor Torque Calculation?

Motor torque calculation determines the rotational force required to produce a specific linear force at a given radius, accounting for system efficiency. This is essential for selecting appropriate motors in mechanical systems.

2. How Does The Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (N·m)
• \( F \) — Force (N)
• \( r \) — Radius (m)
• \( Eff \) — Efficiency (fraction, 0-1)

Explanation: The formula calculates the torque needed to generate a specific linear force at a given distance from the rotation center, adjusted for mechanical efficiency losses.

3. Importance Of Torque Calculation

Details: Accurate torque calculation is crucial for proper motor selection, preventing under-sizing (causing system failure) or over-sizing (increasing costs and energy consumption).

4. Using The Calculator

Tips: Enter force in newtons (N), radius in meters (m), and efficiency as a decimal fraction (e.g., 0.85 for 85% efficiency). All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What is torque in simple terms?
A: Torque is the rotational equivalent of linear force - it's the twisting force that causes rotation around an axis.

Q2: Why is efficiency important in torque calculation?
A: Efficiency accounts for energy losses due to friction, heat, and other factors in the mechanical system, ensuring the motor provides adequate power.

Q3: What are typical efficiency values?
A: Efficiency varies by system: gearboxes (85-95%), belt drives (90-98%), direct drive (95-98%). Always consult manufacturer specifications.

Q4: How does radius affect torque requirements?
A: Larger radius increases torque requirements proportionally - doubling the radius doubles the required torque for the same force.

Q5: Should safety factors be applied?
A: Yes, typically add 15-25% safety margin to calculated torque to account for unexpected loads, wear, and startup conditions.
