Measures for Energy Conservation in Electrical Drives: Following Measures for Energy Conservation in Electrical Drives: Use of efficient semiconductor converters. Use of efficient motors. Use of variable speed drives. Energy…
Energy Losses in Electrical Drive System: Energy conservation in electrical drive is achieved by reduction of losses in its various parts. Typical Energy Losses in Electrical Drive System include the…
Diesel Electric Traction System: Because of high initial cost, electric traction is justified only where there is sufficient volume of traffic. Diesel Electric Traction System is preferable where the traffic…
Electric Traction Services: Electric Traction Services can be broadly classified as: Electric Trains. Electric buses, trams (or tramways) and trolleys. Battery driven and solar powered vehicles. Electric Trains: Electric trains…
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…
Drive Circuits for Stepper Motor: A Drive Circuits for Stepper Motor is usually driven from a low voltage dc source. When a phase is to be energised, the dc source…
Brushless DC Motor Drives(Trapezoidal PMAC): The cross section of a 3-phase 2 pole Brushless DC Motor Drives is shown in Fig. 7.15. It has permanent magnet rotor with wide pole…
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…
