Synchronous Motor,Types of Synchronous Motor,Dc current Excited Motor,Characteristic of Synchronous Motor,Application of Synchronous Motors,Comparision of Synchronous & Induction Motor
Synchronous Motor A Synchronous motor is electrically identical with an alternator or A.C. generator .It can define as an A.C. Motor in which at steady state rotation of the shaft is in Syn with the frequency of the applied current.In Synchronous motor the total number of rotations made by the shaft is equal to the applied current.In Synchronous motors unlike induction motor multiphase A.C electromagnets are present on the stator which produces a rotating magnetic field.Here rotor is of a permanent magnet which gets synced with the rotating magnetic field and rotates in synchronous to the frequency of current applied to it.Most synchronous motors are rated between 150KW and 15MW and run at speed ranging from 150 to 1800 rpm. Types of Synchronous Motor According to the method of magnetization of the rotor we have two types of synchronous motors. Non-excited. Direct current excited. ...
