Explain in detail
As we know that in induction motor 3-phase winding is placed at 120 degree with respect to space and when a 3-phase supply is applied which has 120 degree phase displacemant with respect to time, a rotating magnetic field is produced. But in case of transformer there is no such arrangement is done.
In case of an Induction motor, the Electrical RYB phase voltage and the Mechanical Winding of RYB phase are palced with a 120 Degree Displacement creating the rotating magnetic field whereas the Transformer doesnt have any arrangement of 120 degree displacement between the Electrical RYB phase and the Mechanical RYB windinding.
Both induction motor and transformer works under the principle of Electromagnetic induction. In a transformer, the primary winding and secondary winding are magnetically coupled. Whereas in induction motor, the stator and rotor are magnetically coupled.
1 to produce rotational magnatic feild we need at lease tree phase its like shaire we can not make stable shair with one or two stand we need at least3 , sow in electrical enginiring we use three becouse its its the best between choises less phase mean less complication and moore economic
Basically in Induction motor the magnetic field generated is rotating one means that it is changing in both space domain and time domain and therefore results in motion . While in case of transformer principle is same but the magnetic field generated is varying only in time domain not in space domain therefore it does not rotate.
