SYNCHRONOUS MACHINES

Armature winding of synchronous machine either delivers 3 phase a.c source or its supplied by 3 phase a.c source and the field winding is energized from dc source. As in other rotating machine the emf induced in synchronous machine is motional emf so there must be relative motion between the conductors and magnetic field. Emf […]

STATOR EQUIVALENT CIRCUIT DIAGRAM

MMF Balancing In an Induction machine due to air gap between stator and rotor the magnetizing current drawn by the Stator is must be higher as compare to magnetizing current drawn by the transformer. hence  So usually we ignore   and only consider in the shunt branch. The magnetizing Reactance of a Induction motor is […]
