A generator 10, comprises a first stator 14 comprising a set of electromagnets 24 producing a rotating magnetic field travelling around the first stator 14, a second stator 12 comprising a set of generator windings 26 and a rotor 16 disposed between the first and second stators 12, 14, the rotor 16 comprising a set of core members 32 and a drive pulley 28, wherein the core members 32 are arranged to interact, in the manner of magnetic gearing, with the magnetic field produced by the set of electromagnets 24 to produce a modulated magnetic field that induces an electrical current in the generator windings 26, The rotational speed of the electromagnets field at least in part determines the magnitude of the electrical current induced in the generator windings 26. The generator may be used in a vehicle, the modulated field being controlled in response to engine speed or by a closed loop system responsive to frequency or current/voltage amplitude of the generator output. In a hybrid vehicle the generator may additionally, when not driven by the vehicle, function as a power inverter to remove the need for a low voltage battery. |
