Why induction motor is called as rotating transformer?

already exists.

Would you like to merge this question into it?

already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

it may be because rotating transformer also have one winding turns while the other remains stationary.because the one that was stationary is the one that accepts signals and the one that was turning is the one who converts he signal into current and distribute it to the motors engine

What is the reason of harmonics in transformer and induction motor?

To be very brief, Harmonics are caused because of magnetising current flowing in the primary of transformer, which cause deaviation from the ideal sinusoidal waveform produc

Difference between transformer and induction motor?

1. Induction Motor has an air-gap but transformer has no air gap rather it is mutually link. 2. Induction Motor has high no-load current than transformer. 3. Induction Motor

Why dc motor is not called as an induction motor?

In dc motors, the electric power is conducted directly to the armature (i.e., rotating part) through brushes & commutator. Hence, in this sense a dc motor can be called as a C

Why induction motor is called asynchronous motor?

as we know that a rotating magnetic field is created by the satator current,and so in the rotor there is induced current and there by the rotor developes a unidirectional torq

Why a ac motor is called as a induction motor?

as it works on induced voltage on rotor according to faradays law of electromagnetic inductio ac motors called as induction motor The AC motors works in the same principle a

What is the relationship between an induction motor and transformer?

In an induction motor, power is supplied to the rotor using a changing magnetic flux i.e. without any true conductive contact. Similarly, in a transformer, the power is transf

Why induction motor is also called short circuit transformer?

Like transformer induction motor has stator winding(Primarywinding) and rotor winding(Secondary winding) separated by anairgap. . Rotor winding(generally Al bars) are short c
