Motor Top Speed RPM Calculator
Calculate the top (no-load) speed of an induction motor.
Using:
Synchronous Speed: \( n_{sync} = \frac{120\, f}{P} \)
Top Speed: \( n_{top} = n_{sync}(1 – s) \)
* Enter supply frequency (Hz), number of poles, and slip (as a decimal; e.g., 0.03 for 3%).
Step 1: Enter Motor Parameters
Example: 60 Hz
Example: 4 (typically even numbers: 2, 4, 6…)
Example: 0.03 for 3% slip
