If we have a magnetic field and a ferromagnetic material subjected to this field, the body will rotate until its magnetic axis is aligned with that of the field..
My question is: In asynchronous 3-phase motor, we have a rotating field.. so why we need to make a short circuited rotor and we don't apply the same principle of aligning the magnetic fields in such a motor? why we need a current to flow in the rotor ?
