Abstract
An axial flux induction machine including at least two stator and one rotor where the stators include an inner and outer ring of coils. The stator includes at least two mirrored structure constructed such as to secure wire coils, amplify magnetic characteristics, and provide a structure upon which to secure a rotary shaft or through which a rotary shaft may be run. The structures supporting either the outer or inner ring of coils can be in contact between the two stators and the outer ring can be spaced further from the rotary shaft than the inner ring of coils and also further from the rotary shaft than an outer edge of the rotor.
Claims28
An axial flux machine comprising:
- an axis of rotation;
- a rotor centered around and configured to rotate around the axis of rotation;
- a shaft passing through the axis of rotation and coupled to the rotor thereby rotating when the rotor rotates;
- a first stator and second stator each centered around the axis of rotation and arranged on opposing sides of the rotor, each of the first and second stators comprising:
- an inner ring of high-permeability structures extending towards the rotor;
- and
- an outer ring of high-permeability structures arranged further from the axis of rotation than the inner ring and extending towards the rotor, and wherein the inner and outer rings of high-permeability structures are substantially parallel to the axis of rotation;
- a plurality of inner conductive coils wrapped around one or more of the high-permeability structures in the inner ring;
- and
- a plurality of outer conductive coils wrapped around one or more of the high-permeability structures in the outer ring.
An axial flux machine comprising:
- an axis of rotation;
- a rotor centered around and configured to rotate around the axis of rotation;
- a shaft passing through the axis of rotation and coupled to the rotor thereby rotating when the rotor rotates;
- a first stator and second stator each centered around the axis of rotation and arranged on opposing sides of the rotor, each of the first and second stators comprising:
- an inner means for retaining one or more inner conductive coils;
- and
- an outer means for retaining one or more outer conductive coils, the outer means arranged further from the axis of rotation than the inner means, and wherein the inner and outer means for retaining the one or more inner and outer conductive coils, respectively, extend towards the rotor and are substantially parallel to the axis of rotation;
- and
- one of the one or more of inner conductive coils connected to one of the one or more outer conductive coils to form a first conductive path.
