You may not expect current in neutral of a 3phase
appliance. But there will be current in neutral of a 1
phase appliance while working.,

Answer / pillay

your understanding is wrong or if not
incomplete.
In any single phase circuit the neutral
is the return path
for the circuit. That means the current that
flows into the phase comes out through the neutral
Even in 3 PH balanced load you will see the
same individual ph current in the neutral but
you will see no current in the main neutral,
cos at the neutral bar the individual neutral
current had balanced up through the other phases.

Answer / snk

yes your thinking good and by law should not be flow when
open circuit.but air con working and neutral floe is the
return of current.you make your question in tow parts then it
will be help full.

I have a table fan of Rallifan Make. When I overhauled it I found a stator winding and an aluminum die cast rotor. So it is supposed that it is a 1 phase induction motor. But there are only two terminals coming out and there is no capacitor. Can any one tell how this motor works? or which type of this motor is?
