This tool helps you calculate the rotations per minute (RPM) of a spinning object based on its speed and diameter.
How to Use the RPM Calculator
This RPM calculator helps you determine the RPM of your motor based on the motor’s speed, number of poles, and the frequency. This tool is essential for understanding the operational characteristics of the motor.
Instructions:
- Enter the Motor Speed (RPM) in the input field.
- Enter the Number of Poles of the motor.
- Enter the Frequency (Hz) the motor is running at.
- Click the Calculate button to see the results.
How It Calculates:
The calculator uses the following formulae:
- Synchronous Speed = (120 * Frequency) / Number of Poles
- Slip = ((Synchronous Speed – Motor Speed) / Synchronous Speed) * 100
The results will provide you with the synchronous speed and slip of the motor, which are critical for understanding motor performance and efficiency.
Limitations:
Ensure the values entered are positive numbers. This calculator assumes ideal conditions and does not account for real-world inefficiencies.
