Principle of Operation of Induction Motor: The Principle of Operation of Induction Motor in Figure 9.4 shows the cross-sectional view of an induction motor. The stator is fed from a…
Construction of Induction Motor and Types of Rotor in Induction Motor: The stator of an Construction of Induction Motor is similar to that of a synchronous machine and is wound…
Brushless DC Motor: The term Brushless DC Motor is applied to many configurations of ac synchronous motors in which semiconductor control is used to control stator currents such that maximum…
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…
Short Circuit Current in Synchronous Generator: The Short Circuit Current in Synchronous Generator being electrical in nature is much faster than the electromechanical dynamics discussed already. It will, therefore, be…
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,…
Starting of DC Motors: At the time of Starting of DC Motors (n = 0), the induced emf of a motor is zero such that the current drawn from rated…
Commutation in DC Machine or Generator or Motor: One coil each under an adjoining pole-pair is connected between adjacent commutator segments in a lap-wound dc armature, while in a wave-wound…
