Induction motor works on same principal as transformers work ie faradays law of electromagnetic induction. ie IM called as rotating transformer
Description : The slip of 400 V, three phase, 4 -pole induction motor when rotating at 1440 rpm is
Answer : The slip of 400 V, three phase, 4 -pole induction motor when rotating at 1440 rpm is 4 percent
Description : A 3-phase, 4-pole, 50Hz induction motor runs at a speed of 1440 rpm. The rotating field produced by the rotor rotates at a speed of ________ rpm with respect to stator field. (A) 1500 (B) 0 (C) 1440 (D) 60
Answer : 0
Description : what is mean by rotating transformer ?
Answer : Induction motor is a rotating transformer
Description : Explain how in a 3 phase induction motor to a rotating magnetic field is developed.
Answer : Production of Rotating Magnetic Field in Three-phase Induction Motor: In three-phase induction motor, the three-phase stator windings are displaced in space by 120° and their three-phase currents are displaced ... time by 120°. Such fluxes give rise to the resultant rotating magnetic field.
Description : Define rotating magnetic field of an induction motor.
Answer : Rotating magnetic field of an induction motor: A rotating magnetic field is a magnetic field that has moving polarities in which its opposite poles rotate about a central point or axis.
