Patent ID: 8536751

Claim:
An electromagnetic device with reversible generator-motor operation, the device comprising: a rotor rotating about an axis and bearing a plurality of magnets distributed at regular intervals there around and with alternate orientations in a substantially ring-shaped pattern; a stator comprising at least one set of individual magnetic yokes each having a pair of projecting arms that extend towards the magnets and bear a respective coil for electrical connection to a utilising device or a power driver, a magnetic yoke in each set being part together with a pair of magnets confronting the yoke arms at a given instant, and an air gap separating the yoke from the magnets, of a same closed magnetic circuit; the individual magnetic yokes being independently mounted on supports that are adjustable by a mechanism under the control of an electronic control unit to dynamically adjust the positions of the individual magnetic yokes relative to the magnets during operation of the device.
