Dynamic Modelling of Induction Motor: In general, the mechanical time-constant for any machine is much larger than the electrical time constant. Therefore, the Dynamic Modelling of Induction Motor can be…
Crawling and Cogging in Induction Motor: Crawling and Cogging in Induction Motor - A squirrel-cage rotor may exhibit a peculiar behavior in starting for certain relationships between the number of…
Synchronous Machine Operation: The Synchronous Machine Operation are examined here under conditions of variable load and variable excitation. One of these quantities will be assumed to be held constant at…
Determination of the Synchronous Reactance | Open Circuit and Short Circuit test of Synchronous Machine: Determination of the Synchronous Reactance - With the assumption of a linear magnetic circuit, the…
Construction of Cylindrical Rotor Synchronous Machine: As stated earlier the Cylindrical Rotor Synchronous Machine offers constant permeance to mmf waves irrespective of the mechanical position of the rotor and is,…
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…
Characteristics of Separately Excited DC Generator: With the advent of silicon-controlled rectifiers, the importance of the dc machine as a generator has considerably reduced as SCRs can be employed to…
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…
