1. What is Servo Motor Torque?

Servo motor torque is the rotational force produced by the motor, calculated as the product of torque constant and current. It determines the motor's ability to perform work and overcome load resistance.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (Nm)
• \( Kt \) — Torque constant (Nm/A)
• \( I \) — Current (A)

Explanation: The torque constant represents the motor's efficiency in converting electrical current to mechanical torque.

3. Importance of Torque Calculation

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

4. Using the Calculator

Tips: Enter torque constant in Nm/A and current in Amperes. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical torque constant value?
A: Torque constant values vary by motor size and type, typically ranging from 0.01 to 1.0 Nm/A for most servo motors.

Q2: How does temperature affect torque calculation?
A: Motor heating can reduce torque constant slightly due to increased resistance, but the basic T = Kt × I relationship remains valid.

Q3: Can this formula be used for all motor types?
A: This formula is specifically for permanent magnet servo motors. Other motor types may have different torque characteristics.

Q4: What is the relationship between torque and speed?
A: For a given voltage, torque decreases as speed increases due to back EMF, though this calculator focuses on the current-torque relationship.

Q5: How accurate is this calculation?
A: The calculation provides theoretical torque. Actual torque may vary due to factors like efficiency losses, temperature, and magnetic saturation.
