1. What is AC Motor Torque?

AC motor torque is the rotational force produced by an alternating current motor. It represents the motor's ability to perform work and is a critical parameter in motor selection and application design.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (Newton-meters, N·m)
• \( P \) — Power (Watts, W)
• \( \omega \) — Angular velocity (radians per second, rad/s)

Explanation: This formula calculates the torque produced by an AC motor based on its power output and rotational speed.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for proper motor selection, ensuring the motor can handle the required load, and optimizing system performance in various industrial applications.

4. Using the Calculator

Tips: Enter power in watts and angular velocity in radians per second. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between torque and power?
A: Torque and power are directly proportional when angular velocity is constant. Higher power output generally results in higher torque production.

Q2: How does angular velocity affect torque?
A: For a given power output, torque decreases as angular velocity increases, following the inverse relationship in the formula T = P/ω.

Q3: What are typical torque values for AC motors?
A: Torque values vary significantly based on motor size and type, ranging from fractional N·m for small motors to thousands of N·m for large industrial motors.

Q4: Can this calculator be used for DC motors?
A: Yes, the fundamental torque formula T = P/ω applies to both AC and DC motors, though specific motor characteristics may differ.

Q5: How accurate is this calculation for real-world applications?
A: While the formula provides theoretical torque, actual torque may vary due to factors like motor efficiency, load conditions, and operating temperature.
