Induction vs Synchronous Machines • Engineering Scribbles

WebWhenever the magnetic structure of a Cylindrical Rotor Synchronous Machine is subjected to rotating mmf vector, it is seen as an mmf phasor from the stator with its flux phasor in phase with it, while the phasor representing the phase emf induced lags behind both these phasors by 90° (see Fig. 8.3). It was shown in already that when a 3-phase ... Webelectromechanical model of induction motors needs reference frame theory, because induction motors, although similar to synchronous machines, are different from synchronous machines. The upshot here is that load modeling is our first motivation for being interested in induction machines and reference frame theory. shiseido hair color
