Abstract

The invention relates to an energy efficient induction motor comprising a stator, a main winding (M) of the stator for generating a rotating magnetic field (RMF), and a rotor disposed to rotate relative to the main winding (M) of the stator due to the RMF. The stator comprises additional windings (A) for producing an alternating EMF which is induced in the one or more additional windings (A) due to the rotation of the rotor. The alternating EMF produced in the one or more additional windings (A) is fed back simultaneously to the main winding (M) of the stator throughout the complete rotation cycle of the rotor through an electronic control unit coupled to the stator, producing a resultant AC output power that is fed continuously to the main winding (M) of the stator.
