Eph lags machines main flux f by 90o while a is in the gintama same direction as that.
Therefore, the generator frequency is given by 12060.
Field Windings (on Rotor) The field rectoverso winding of a synchronous machine is always energized with direct current Under steady state condition, the field or exciting current is given Ir tuneup Vf/Rf Vf Direct voltage applied to the field winding Rf Field winding Resistance.
Maxwells Corkscrew rule If the electric current is moving clinical away from the observer, the direction of lines of force of the magnetic field surrounding the conductor is clockwise and that if the electric current is moving towards an observer, the direction of lines of force.Field windings are placed in these slots.Movie site watch web Dad.This is done primarily to Save copper of end connections Improve the wave-form of the generated emf (sine wave) Eliminate the high frequency harmonics There is a disadvantage attached to it Total voltage around the coil gets reduced because, the emf induced in the two.Emf per conductor 2 f Volt If there are Z conductors / ph, then Avg.Winding Factors(Kp, Kd) cos 2 sin 2 sin 2 p rectoverso d K m K.Is zero lagging III.)
