Single Phase Synchronous Generator: Certain applications, usually restricted to less than 10 kVA are better served by a Single Phase Synchronous Generator. Examples are emergency, domestic/office supply, portable power for…
Introduction of DC Motor: Introduction of DC Motor is constructed in many forms and for a variety of purposes, from the 3-mm stepper drawing a few μA at 1.5 V…
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…
DC Motor Losses and Efficiency: The Losses and Efficiency of a transformer have been studied in earlier lesson. As in the case of transformers, it is more accurate to determine…
Types of Magnetic Leakage Flux in Induction Motor: The Magnetic Leakage Flux in Induction Motor is that flux which links only the stator or only the rotor windings. Because of…
Principle of Induction Motor | Torque Slip Characteristic: Principle of Induction Motor has not been introduced so far. Consider a cylindrical rotor machine with both the stator and rotor wound…
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…
