Answer / sailendra narayan sethi

terminal voltage will remain constant.

Answer / arvind

you may be knowing about the equal area crietria, in this
as suddenly you disconnect the busbar from the alternator,
the rotor of alternator may lose the syncronism and
terminal voltage will be zero, and accrding to the relation
p=pm-pe, where pm is mechanical power and,
pe is electrical power
when pe=0 that means p=pm, it means only mechanical power
will be there.

can we do the star delta connection of capacitor for 3- phase motor starter.

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?
