DC Motor Electric Brakes: DC Motor Electric Brakes - While operating electrical drives it is often necessary to stop the motor quickly and also reverse it. In applications like cranes…
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…
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…
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…
Define Permanent Magnet in Magnetic Circuits: Define of Permanent Magnet is an important excitation source (life long) commonly employed for imparting energy to magnetic circuits used in rotating machines and…
Magnetic Properties of Materials: Magnetic Properties of Materials - From the magnetic point of view a material is classified according to the nature of its relative permeability (μr). All nonmagnetic…
Dynamic Characteristics: Instruments rarely respond instantaneously to changes in the measured variables. Instead, they exhibit slowness or sluggishness due to such things as mass, thermal capacitance, fluid capacitance or electric…
