1. What is the Torque Formula?

The torque formula T = Kt × I calculates the torque produced by an electric motor, where Kt is the torque constant and I is the current flowing through the motor. This relationship is fundamental in motor control and electromechanical systems.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

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

Explanation: The formula demonstrates the direct proportional relationship between torque and current in electric motors, with the torque constant serving as the proportionality factor.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for motor selection, performance analysis, control system design, and ensuring proper operation of mechanical systems driven by electric motors.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the torque constant (Kt)?
A: The torque constant is a motor-specific parameter that relates the current input to the torque output, typically provided in the motor's datasheet.

Q2: Does this formula apply to all types of motors?
A: This formula primarily applies to DC motors and brushless DC motors where torque is directly proportional to current.

Q3: How accurate is this calculation?
A: The calculation is mathematically precise, but actual motor performance may vary due to factors like temperature, saturation, and efficiency losses.

Q4: Can I use this for AC motors?
A: For AC motors, the relationship is more complex and depends on power factor and other parameters. This simple formula is not directly applicable.

Q5: What are typical units for torque constant?
A: The torque constant is typically expressed in Newton-meters per Ampere (Nm/A) or sometimes in ounce-inches per Ampere (oz-in/A).
