Enter any two values and leave the third field empty, then click Calculate to find the missing value.
The number of poles must be an even integer (2, 4, 6, ...). An approximate pole-count result is rounded to the nearest even integer.
Equation Used
Where N is the synchronous speed in revolutions per minute, f is the grid frequency in hertz, and P is the number of poles (always an even number).
A generator with four poles (P = 4) connected to a grid with a frequency of 50 Hz:
This means the generator must rotate at exactly 1500 revolutions per minute to produce a synchronous frequency of 50 Hz.
