Answer Posted / rvg
Dear Mr. Gajanan, as you are dealing with more machineries,
i want to stress some points:
During starting of motor:
the armature(rotor) is stationary, and it does not having
any magnetic property to resist the applied rotational
frequency at that time.
so it will act as a conductor fixed at rotating magnetic
field and produce some eddy current loss, and with in short
period of time, it will develope some anti rotional effect
to resist the rotational field, ie: rotating with same
direction to reduce the eddy curent.Thats why after
starting current reduces.
inertia of the rotor also having some major role on the
starting current. The gap between rotor and stator having
role on the starting current and initial power factor.
