1. What is Motor Torque?

Motor torque is the rotational force produced by an electric motor. It represents the motor's ability to perform work and is a crucial parameter in motor selection and application.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (Nm)
• \( P \) — Power (kW)
• \( N \) — Speed (rpm)
• 9550 — Conversion constant

Explanation: The formula calculates the torque output of a motor based on its power and rotational speed, using the standard conversion factor of 9550.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for proper motor selection, ensuring the motor can handle the required load and operate efficiently in various applications.

4. Using the Calculator

Tips: Enter power in kilowatts (kW) and speed in revolutions per minute (rpm). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of the constant 9550?
A: The constant 9550 is derived from the conversion between different units of power and rotational speed to calculate torque in Newton-meters.

Q2: Can this formula be used for all types of motors?
A: This formula is generally applicable to electric motors, but specific motor types may have additional factors that affect torque calculation.

Q3: How does torque relate to motor performance?
A: Torque determines the motor's ability to overcome resistance and perform work. Higher torque indicates greater rotational force capability.

Q4: What are typical torque values for different motor sizes?
A: Torque values vary significantly based on motor design and application. Smaller motors typically produce lower torque, while larger industrial motors can produce substantial torque.

Q5: How does speed affect torque in electric motors?
A: For a given power, torque is inversely proportional to speed. As speed increases, torque decreases, and vice versa.
