Synchronous MachinesConstruction1. Stator - armature (Same as the stator of an InductionMachine)2. Rotor - Field winding ( DC Field)GeneratorIAs a generator, this machine is widely is the machine which is used in all conventional Synchronous generator is called as an it runs only at Synchronous speed, it is not widely usedas a motor but for certain applications like electric , it is used to either produce or absorb reactive StatorIIt is a distributed windings of each phase are distributed over several phase windings are wound 120 (electrical angle) apartin space2. RotorIIt is excited by a DC are two Cylindrical Rotor - used where the turbine speed is Salient Pole Rotor - used where the turbine speed is lowSynchronous machine is a doubly excited can have field winding placed in stator and armature windingin rotor.
IStator (armature) is connected to a three phase AC supply. IRotor ( eld winding) is connected to a DC supply. Unlike three phase induction motors and DC motors, synchronous motors are not self-starting. let us consider a 4-pole synchronous machine. IWhen the three phase armature winding (stator) is supplied with a three phase balanced supply ...
