External Characteristics of Compound Generator: External Characteristics of Compound Generator - The causes of voltage drop in the terminal voltage from no-load to full-load in a shunt generator can be…
Self Excited DC Generator: Rather than arranging a separate dc source for excitation purposes, practical generators are always excited from their own armature terminals, this method of excitation being known…
Magnetization Characteristics of DC Generator: The emf and torque equations, and power balance has been considered so far. The consideration of the Magnetization Characteristics in this section will set the…
Methods of Excitation of DC Generator: The performance characteristics of a dc machine are greatly influenced by the way in which the field winding is excited with direct current. There…
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…
2 Pole Elementary DC Machine: Figure 5.13 shows a 2 Pole Elementary DC Machine with a single coil rotating armature. It may be seen that the field winding is stationary…
Synchronous Machine Working Principle: Figure 5.2 shows the simplified version of an ac Synchronous Machine Working Principle with a 2-pole field winding on the rotor and a single coil aa'…
