1. What is Max Torque Calculation?

The max torque calculation determines the maximum rotational force a motor can produce at a given speed and power. It's a critical parameter in motor selection and mechanical design applications.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( T_{max} \) — Maximum torque (Nm)
• \( P_{max} \) — Maximum power (kW)
• \( N \) — Rotational speed (rpm)
• 9550 — Conversion constant (derived from unit conversions)

Explanation: The formula converts power and speed into torque, accounting for the relationship between rotational power and force.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for proper motor sizing, mechanical system design, and ensuring equipment operates within safe operational limits.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why is 9550 used in the formula?
A: 9550 is a conversion constant derived from unit conversions (1 kW = 1000 W, 1 minute = 60 seconds, and 2π radians per revolution).

Q2: What are typical torque values for electric motors?
A: Torque values vary significantly based on motor size and type, ranging from fractional Nm for small motors to thousands of Nm for large industrial motors.

Q3: How does speed affect torque in this calculation?
A: Torque is inversely proportional to speed - at constant power, higher speeds result in lower torque, and vice versa.

Q4: Can this formula be used for all types of motors?
A: This formula provides theoretical maximum torque and is generally applicable to various motor types, though actual performance may vary based on motor characteristics.

Q5: What's the difference between max torque and rated torque?
A: Max torque is the peak torque a motor can produce, while rated torque is the continuous torque it can sustain without overheating.
