Compensating Winding in DC Machine: Compensating Winding in DC Machine - It was seen from earlier section, that armature reaction causes the flux density wave to be so badly distorted…
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.…
Synchronous Generator Ratings and Loss Dissipation: The Synchronous Generator Ratings and Loss Dissipation is its operating voltage, frequency, speed and kVA/MVA output at a specified power factor. In case of…
Torque Equation of Synchronous Motor: Figure 5.36 shows a Torque Equation of Synchronous Motor with a round rotor. The rotor is initially stationary with fixed north-south poles created by dc…
Torque in Round Rotor Synchronous Machine: Torque in Round Rotor Synchronous Machine - When the stator and rotor windings of a machine both carry currents, they produce their own magnetic…
Rotating Magnetic Field: Rotating Magnetic Field - It was seen earlier that the sinusoidal current in any phase of an ac winding produces a pulsating mmf wave in space whose…
Sinusoidally Distributed Current Sheet Concept: It was seen above that a distributed winding gives rise to a stepped mmf wave having a strong fundamental component which will be considered in…
MMF of AC Distributed Winding: It has been seen earlier that the armature what-when-how.comof a practical machine has distributed winding wound for the same number of poles as the field…
