Abstract
The invention provides a reluctance generator for an eddy current braking system in a vehicle. The reluctance generator has a field winding and a compensation winding, which induce magnetomotive forces. The magnetomotive force induced by the compensation winding balances the magnetomotive force generated by a rotor in the reluctance generator. The field winding has less inductance.
Claims29
A reluctance generator for an eddy current braking system in a vehicle, comprising:
- a stator assembly defining a core apace, the stator assembly comprising a field winding and a compensation winding, the field winding operable to induce a field magnetomotive force (MMF) in respons, to a first excitation, the compensation winding operable to induce a compentation magnetomotive force (MMF) in response to a second excitation;
- a rotor disposed in the core space, the rotor operable to generate an armature magnetomotive force (MMF);
- lamination sections disposed along an interior surface of the stator assembly;
- and
- an armature winding disposed about portions of the lamination sections.

A reluctance generator for en eddy current braking system, comprising:
- lamination sections disposed along an interior surface of a stator assembly, the lamination sections defining a core space and a winding volume;
- a field winding disposed along an outer portion of the winding volume, the field winding operable to induce a field magnetomotive force (MMF) in response to a first excitation;
- a compensation winding disposed along an inner portion of the winding volume, the compensation winding operable to induce a compensation magnetomotive force (MMF) in response to a second excitation;
- an armature winding disposed in the lamination sections;
- and
- a rotor disposed in the core space, the rotor comprising a first section and a second section disposed on opposite sides of a center ring mounted on a shaft, the center ring aligned with the excitation and compensation windings, the rotor operable to generate an armature magnetomotive force (MMF),
- where the compensation MMF balances the armature MMF.
