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 (Newton-meters)
• \( P \) — Power (kilowatts)
• \( N \) — Speed (revolutions per minute)
• 9550 — Conversion constant

Explanation: The formula calculates the torque output of a motor based on its power rating and rotational speed.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for proper motor selection, ensuring the motor can provide sufficient rotational force for the intended application without overloading.

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 unit conversions between kilowatts, Newton-meters, and revolutions per minute.

Q2: How does torque relate to motor performance?
A: Torque determines a motor's ability to overcome resistance and maintain rotation under load. Higher torque means better starting and running performance.

Q3: What factors affect motor torque?
A: Motor design, power supply, load characteristics, and operating temperature all influence the torque output of a motor.

Q4: What is the difference between starting torque and running torque?
A: Starting torque is the torque produced at zero speed, while running torque is the torque available during normal operation at rated speed.

Q5: How can I increase motor torque?
A: Torque can be increased by using gear reducers, selecting motors with higher power ratings, or using motors specifically designed for high-torque applications.
