hi there,
from what i know there are 3 factors which determine the speed of a 3phase induction motor which are:
i) frequency
ii) number of poles
iii) resistances of the windings.
As for premise (ii), the lower the number of poles, the faster the speed of the motor. Why is that so? Shouldn't the speed increase as there are more magnetic fields in the stator thus producing more e.m.f to drive the rotor?
help is greatly appreciated
thanks!
