Abstract
The invention relates to an energy efficient induction motor comprising a stator, a main winding of the stator for generating a rotating magnetic field (RMF), and a rotor disposed to rotate relative to the main winding due to the RMF. The stator comprises additional winding(s) for producing an alternating EMF which is induced in the one or more additional windings due to the rotation of the rotor. The alternating EMF produced in the one or more additional windings is fed back simultaneously to the main winding 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.
Claims16
An induction motor, comprising:
- a stator comprising a main winding configured to generate a rotating magnetic field (RMF) in response to the main winding of the stator receiving a resultant AC output power;
- and
- a rotor disposed to rotate relative to the main winding of the stator due to the RMF,
- wherein the stator further comprises one or more additional windings, wherein rotation of the rotor induces an alternating EMF in the one or more additional windings of the stator, wherein the alternating EMF produced in the one or more additional windings is fed back to the main winding of the stator throughout the complete rotation cycle of the rotor through an electronic control unit (ECU) coupled to the stator, wherein the ECU comprises:
- a rectifier circuit for converting AC voltage of a main AC power supply to a first DC power and for converting the alternating EMF produced in the one or more additional windings to a second DC power, wherein a resultant DC power is obtained by adding the first DC power and the second DC power;
- and
- an inverter circuit for converting the resultant DC power to the resultant AC output power,
- wherein the ECU is configured to feed the resultant AC output power to the main winding of the stator.
