Battery Powered Vehicles: Battery Powered Vehicles - These are popularly known as electric vehicles. Although several batteries and fuel cells have been developed, only available at affordable price is the…
Solar Panels or Photovoltaic Cells: A Solar Panels or Photovoltaic Cells converts sunlight into electricity. Single crystal, polycrystal and amorphous silicon cells have been employed. The open circuit voltage is…
Switched Reluctance Motor: The switched reluctance motor (SRM) has both salient pole stator and rotor, like variable stepper motor, but they are designed for different applications, and therefore, with different…
Sinusoidal PMAC Motor: Since the voltages induced in the stator phases of a sinusoidal PMAC motor are sinusoidal, ideally, the three stator phases must be supplied with variable frequency sinusoidal…
Self Controlled Synchronous Motor Drive: A Self Controlled Synchronous Motor Drive employing a load commutated thyristor inverter is shown in Fig. 7.10. In large power drives wound field synchronous motor…
Three Phase Induction Motors: Three Phase Induction Motors are of two types: squirrel-case and wound-rotor. In squirrel-cage, the rotor consists of longitudinal conductor-bars shorted by circular connectors at the two…
Chopper Control of Separately Excited DC Motor: Motoring Control : A transistor Chopper Control of Separately Excited DC Motor drive is shown in Fig. 5.41(a). Transistor Tr is operated periodically…
Ward Leonard Method of Speed Control: Known after the name of its inventor Ward Leonard Method of Speed Control (1891), it consists of a separately excited generator feeding the dc…
