Rotor E.M.F.
In an induction motor, we can see a single 3 phase transformer have equal value with a secondary short-circuited one. This only takes place when a rotor is in a stationary mode. So, in a phase E2 when e.m.f is induced at the very moment of starting, its equation is,
In accordance to it, a rotor’s relative speed in comparison to its slip or stat or flux will showcase a decrease as soon as that rotor’s speed will increase. This will be denoted by sE2.
Therefore, at stationary mode,
e.m.f that is induced in rotor = s times x e.m.f that is induced in rotor at speed.
