f=P*N/120
f=Frequency in Hz
P= No. of Poles
N=Rotor Speed in Revolution per minute(rpm)
for P=4 and N=3600, f comes out to be 120 Hz.
So frequency of voltage produced is 120 Hz. But this is not practical. Generally 4-Pole generator has N=1500rpm(for 50 Hz) or 1800rpm for 60 Hz. Two pole generator can have N=3600rpm(f=60Hz).
The most practical situation is generator having N=3600Hz with 2 Poles.
Hope It will be helpful!!!
What else can I help you with?
How do you hack a 4pole 3 phase car alternator to get ac voltage?
The alternator has six diodes inside to recify the ac that is generated. One side of the diodes is the ac side, so maybe you can solder on three live wires and use the case as the neutral, then you have 3-phase four wire, about 300 watts.
In a fan fast turn or slow turn takes more current?
Fast speed requires more current than slow speed on the same motor unless the slower speed is caused by additional load. Two motors, one turns 1725 RPM and the other equal hp motor turns 3450 RPM, each draw same current because AC motors run at speeds close to the synchronus speed of the rotor poles. 2pole, 3600; 4pole, 1800.
Difference between 3 pole and 3 phase?
Phases in AC refer to the number of sine waves of alternating current used to generate the average voltage. In 2 phase, two opposing sine waves are overlapped to give the average voltage delivered, eg 240V in household supplies. In 3 phase, three sine waves are overlapped to produce a more consistent average voltage.
