Answer / amrit.tics

In the said case that, if the rotor of the induction motor
is purely inductive then the electromagnetic torque:-
in that case the rotor current (I2) lags behind the rotor
emf (E2) by an angle > = tan-1 X2/R2.
R2= Rotor Resistance/Phase.
X2= Rotor Reactance/Phase, at standstill.
So it is seen that forward torque & backward torque will
equal & if angle is 90 deg. then total torque will be zero.

why there is no current in the rotor body althrough the flux linking with it also get changes. why current only flows in windinds not in rotor

Why we transmit the power at the voltage in the multiple of 11 or 1.1 like 11kv, 22kv, 66kv, 132kv...... some one told me that it is due to fomr factor 1.1 of sine wave. its fine but while transforming we can choose any voltage, so why only multiple of 1.1 there also.......? plz tell me.
