Oxidation in IC Fabrication: Oxidation in IC Fabrication is very important process. In one line, oxidation can be explained as the production of SiO2 using the thermal growth technique. Some…
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…
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…
Separately Excited DC Motor for Dynamic Analysis: Separately Excited DC Motor for Dynamic Analysis - The DC machines are quite versatile and are capable of giving a variety of V-A…
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…
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…
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…
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…
