Hi Dear Friends,
The speed of the synchronous Motor is given by the equation:
s=120 x f/n where
s = speed in rpm
f = frequency
n = no of pole (here starts the confusion)
My confusion starts with the n (no of poles) whether it refers to the no of poles of the stator windings or no of poles of the rotor winding, and if it refers to the stator no of poles, does that meant that the no of poles of the rotor has no effect on the speed.
If so what is the effect of the increasing the no of poles of the rotor ( and what is the restriction of the no of poles rotor)
