Armature Reaction in Synchronous Generator: The Armature Reaction in Synchronous Generator is dependent on the power factor at which the machine is operating and upon the operating mode generating/motoring. For…
Armature Reaction in Synchronous Motor: The Simple circuit model of the synchronous machine was obtained in Sec. 8.3 by making the assumption that the magnetic circuit of the machine is…
Armature Reaction in DC Machine: When the armature of a dc machine carries current, the distributed armature winding produces its own mmf (distributed) known as armature reaction in DC Machine.…
Transfer Function of Armature Controlled DC Motor: The speed of a dc motor can be controlled by varying the voltage applied to the armature of a dc motor. A separately…
Two Reaction Model of Salient Pole Synchronous Machine: In a Two Reaction Model of Salient Pole Synchronous Machine, the flux established by a mmf wave is independent of the spatial…
Armature Control Method: The main requirement of this Armature Control Method scheme is a variable voltage supply to the armature whose current rating must be somewhat larger than that of…
Paralleling Field Coils for DC Series Motor: In this Paralleling Field Coils method, used in fan motors, several speeds can be obtained by regrouping of field coils, as illustrated in…
Special Features of Thyristor Drive Motors: The most commonly used dc motors for thyristor drive are separately excited and series excited dc motors. The thyristor drive motors usually differ from…
