Diffusion Process in IC Fabrication: Diffusion is the oldest technique used to add impurity into the Substrate. The main aim of the Diffusion Process in IC Fabrication is to change the…
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,…
Braking of DC Motors: Controlled slowing or stopping of a motor and its driven load is as important as starting in many applications (e.g. cranes, traction on a slope to…
EMF and Torque Equation of DC Machine: EMF and Torque Equation of DC Machine - It was shown in Sec. 5.2 (Fig. 5.14 (a)) that in a dc machine the…
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…
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…
