1. What is the Torque Calculation Formula?

The torque calculation formula T = (P × 9550) / N is used to calculate the torque of an electric motor based on its power output and rotational speed. This formula is widely used in engineering and mechanical applications.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

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

Explanation: The formula converts power in kilowatts and rotational speed in revolutions per minute to torque in Newton-meters.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for motor selection, mechanical design, and ensuring proper operation of electric motors in various applications.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of the constant 9550?
A: The constant 9550 is derived from unit conversion factors to convert power (kW) and speed (rpm) to torque (Nm).

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 to consider.

Q3: What are typical torque values for electric motors?
A: Torque values vary significantly based on motor size, type, and application, ranging from fractional Nm to thousands of Nm.

Q4: How does torque relate to motor performance?
A: Torque determines a motor's ability to overcome load resistance and perform mechanical work.

Q5: Can this calculator be used for hydraulic motors?
A: While the basic principle is similar, hydraulic motors may require different calculation methods due to their operating characteristics.
