Abstract
A method and apparatus for generating power in a rotating environment without access to the axis of rotation. A non-center engagement generator is implemented within the rotating reference frame of a vehicle wheel. Further, a method and apparatus detect a potential rollover state and prevent occurrence of a rollover state or eliminate a rollover state once attained.
Claims23
An apparatus comprising:
- a generator implemented in a rotating reference frame;
- a battery for storing electrical power generated by the generator;
- and
- a rollover state detection means to detect a potential or actual rollover state of a stator of the generator.
1 more element
An assembly comprising:
- a wheel having a rotating reference frame;
- an electrical system implemented within the rotating reference frame;
- and
- a generator implemented within the rotating reference frame to supply electrical power to the electrical system such that the generator does not access an axis of rotation of the rotating reference frame, the generator comprising:
- one or more magnetic circuits, each magnetic circuit having elements attached to the rotating reference frame, wherein the elements are implemented as one or more freely moving members each having areas of high magnetic permeability and areas of low magnetic permeability, and a plurality of bearings interfaced to the rotating reference frame using a slip interface such that upon rotation of the rotating reference frame, a change in a position of the elements with respect to a position of the bearings causes a change in a magnetic flux through the magnetic circuit;
- and
- one or more electrical circuits having one or more conductor paths that form at least one closed loop around a portion of the magnetic circuit.
4 more elements
An apparatus comprising:
- a rotating reference frame of a vehicle wheel having an axis of rotation;
- and
- a constant slip generator implemented within the rotating reference frame, the generator not accessing the axis of rotation wherein the generator comprises:
- one or more magnetic circuits, each magnetic circuit having first elements attached to the rotating reference frame and second elements interfaced to the rotating reference frame using a slip interface such that upon rotation of the rotating reference frame, a change in a position of the first elements with respect to a position of the second elements causes a change in a magnetic flux through the magnetic circuit;
- and
- one or more electrical circuits having one or more conductor paths that form at least one closed loop around a portion of the magnetic circuit.
3 more elements
An apparatus comprising:
- a rotating reference frame of a vehicle wheel having an axis of rotation;
- and
- a variable slip generator implemented within the rotating reference frame, the generator not accessing the axis of rotation wherein the generator comprises:
- one or more magnetic circuits, each magnetic circuit having first elements attached to the rotating reference frame and second elements having a center of gravity that is coincident with the axis of rotation of the reference frame interfaced to the rotating reference frame using a slip interface such that upon rotation of the rotating reference frame, a change in a position of the first elements with respect to a position of the second elements causes a change in a magnetic flux through the magnetic circuit;
- and
- one or more electrical circuits having one or more conductor paths that form at least one closed loop around a portion of the magnetic circuit.
