Coefficient of Adhesion in Traction: In Coefficient of Adhesion in Traction, the task of driving equipment consists of pushing the carriage on which it is mounted and pulling coaches and…
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…
Pole Changing of Induction Motor: Pole Changing of Induction Motor - For a given frequency, the synchronous speed is inversely proportional to the number of poles. Synchronous speed, and therefore,…
Harmonic Equivalent Circuit of Induction Motor: When fed from an inverter or cycloconverter, the motor terminal voltage is non-sinusoidal but it has half-wave symmetry. A non-sinusoidal waveform can be resolved…
Motor Rating Various Duty Cycles: From the point of view of calculation of motor rating various Motor Rating Various Duty Cycles can be broadly classified as: Continuous duty. Fluctuating loads.…
Fiber Optic Communication Articles: Fiber Optics History: In 1870 John Tyndall, a natural philosopher living in England, demonstrated one of the first guided light systems to the Royal Society. His…
Fiber Optic Components and Systems: The Fiber Optic Components and Systems can be divided into subgroups, the source, the link, and the detectors. We will now explore the makeup and…
