MMF of AC Distributed Winding: It has been seen earlier that the armature what-when-how.comof a practical machine has distributed winding wound for the same number of poles as the field…
Arc Furnace - Definition, Types, Advantages and Application: When a high voltage is applied across an air gap, the air in the gap gets ionised under the influence of electrostatic…
Systems of Track Electrification AC Electrification System: As even in single phase electrification, the substations are necessarily required to keep the voltage drop within permissible limits. The type of substations…
Rotating Machines Articles: Rotating Electrical Machines: We Know that electromechanical energy conversion takes place whenever a change in flux is associated with mechanical motion. Speed voltage is generated in a…
Fractional Kilowatt Motors Articles: Single Phase Induction Motor: A Single Phase Induction Motor comprises a single-phase distributed winding on the stator and normal squirrel-cage rotor as shown schematically in Fig.…
DC Machines Articles: 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…
Methods to Leading Power Factor: We have seen that a phase controlled converter requires reactive power for control and commutation. The harmonics do not contribute to the active power loading…
