We calculate the frequency with the formula beneath:
f = p*n/60 | f: the frequency in Hz |
p: the number of pole pairs | |
n: the engine speed in rpm |
In the table below, you will find a few examples we calculated using this formula.
Pole pairs | Engine speed (rpm) | Frequency (Hz) |
---|---|---|
1 | 3000 | 50 |
2 | 1500 | 50 |
4 | 750 | 50 |
4 | 3000 | 200 |
8 | 1500 | 200 |
8 | 3000 | 400 |
In some countries, they have other frequencies, which causes the engine speeds to change as well.
