The No-Load RPM of a motor can be calculated using the following formula:
\( \text{No-Load RPM} = \frac{\text{Hz} \times 60 \times 2}{\text{Number of Poles}} \)
- \( \text{Hz} \): Frequency of the power supply (in Hertz).
- \( \text{Number of Poles} \): The number of magnetic poles in the motor (e.g., 2, 4, 6, etc.).
- \( \text{No-Load RPM} \): Revolutions Per Minute under no load (to be calculated).
If the frequency (\( \text{Hz} \)) is 60 Hz and the number of poles is 2:
\( \text{No-Load RPM} = \frac{60 \times 60 \times 2}{2} = 3600 \, \text{RPM} \)
This calculator helps determine the no-load RPM of a motor based on the power supply frequency and the number of poles, useful in electrical engineering and motor design.
Yes, the calculator supports frequency in Hz and kHz. All inputs are converted to Hz for accurate calculations.
Common values for the number of poles in motors are 2, 4, 6, or 8, depending on the motor design and application.
Entering zero for the number of poles will result in no calculation, as division by zero is undefined. Please ensure this value is greater than zero.
The results are displayed in multiple units (RPM, rad/s) to allow you to use the value in your preferred unit.
