Abstract
The disclosure relates to an energy efficient motor-generator which includes 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 further includes a first additional winding (F) for producing an alternating EMF and a second additional winding (E) for producing a corresponding alternating EMF due to the rotation of the rotor. The two alternating EMFs are harvested through an electronic control unit (ECU) interfaced to the stator for continuously supplying power for the working of the motor-generator and for supplying power to drive electrical loads, respectively.
Claims26
A motor-generator, comprising:
- a stator comprising a main winding configured to generate a rotating magnetic field (RMF) upon providing a main AC power supply to the main winding of the stator;
- an electronic control unit (ECU) interfaced to the stator;
- and
- a rotor disposed to rotate relative to the main winding of the stator due to the RMF, wherein:
- the stator further comprises a first additional winding and a second additional winding, wherein a rotation of the rotor induces an alternating EMF in the first additional winding of the stator, wherein the alternating EMF induced in the first additional winding is fed back to the main winding of the stator throughout a rotation cycle of the rotor,
- wherein the rotation of the rotor further induces an alternating EMF in the second additional winding of the stator, wherein the alternating EMF induced in the second additional winding is harvested through the ECU interfaced to the stator to supply power to an electrical load.
A method comprising:
- generating a rotating magnetic field (RMF) in response to a main AC power supply using a main winding of a stator, the stator interfaced to an electronic control unit (ECU);
- rotating a rotor relative to the main winding of the stator in response to the RMF;
- inducing an alternating EMF in a first additional winding of the stator in response to the rotation of the rotor;
- feeding back the alternating EMF induced in the first additional winding to the main winding of the stator throughout a rotation cycle of the rotor;
- inducing an alternating EMF in a second additional winding of the stator in response to the rotation of the rotor;
- and
- harvesting the alternating EMF induced in the second additional winding through the ECU interfaced to the stator to supply power to an electrical load.
