why celing fan is running in anti clock wise and table fan
is running in clock wised?
Answer Posted / hameedullah
Direction of rotation has nothing to do with rotor or
slator. It is the pitch or angle of blades which are
required to run in the required direction (clock or
anticlock wise)for blowing air and not sucking the air. The
direction of any fan or motor can be changed
by "Capicitor's terminals".

I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
