Abstract
A stator module pack for an axial flux electric machine includes a housing for attachment to a stator base, a plurality of stator modules attached to the housing, and a drive unit attached to the housing. Each stator module includes a core having at least one winding disposed thereon. The drive unit is electrically connected to at least one stator module. A plurality of stator module packs and a plurality of drive units are coupled to the stator base to form a stator of the axial flux electric machine.

A stator module pack for an axial flux electric machine, said stator module pack comprising:
- a housing having a face surface and a base surface, the housing defining an enclosed volume, the face surface configured to be positioned adjacent to a rotor, the base surface configured for attachment to a stator base, and wherein housing has a length less than a circumference of the stator base;
- a plurality of stator modules attached to said housing between the face surface and the base surface and within the enclosed volume, each stator module comprising a core having at least one winding disposed thereon;
- and
- a drive unit attached to said housing and electrically connected to at least one stator module of said plurality of stator modules.
A stator for an axial flux electric machine, said stator comprising:
- a stator base;
- and
- a plurality of stator module packs attached to said stator base, each stator module pack of said plurality of stator module packs comprising:
- a housing having a face surface and a base surface, the housing defining an enclosed volume, the face surface configured to be positioned adjacent to a rotor, the base surface configured for attachment to a stator base, and wherein housing has a length less than a circumference of the stator base;
- a plurality of stator modules attached to said housing between the face surface and the base surface and within the enclosed volume, each stator module comprising a core having at least one winding disposed thereon;
- and
- a drive unit electrically connected to at least one stator module of said plurality of stator modules.
A three phase stator module pack for an axial flux electric machine, said stator module comprising:
- a housing having a face surface and a base surface, the housing defining an enclosed volume, the face surface configured to be positioned adjacent to a rotor, the base surface configured for attachment to a stator base, and wherein housing has a length less than a circumference of the stator base;
- a first subset of stator modules attached to said housing between the face surface and the base surface and within the enclosed volume;
- a second subset of stator modules attached to said housing between the face surface and the base surface and within the enclosed volume;
- a third subset of stator modules attached to said housing between the face surface and the base surface and within the enclosed volume, each stator module of said first, second and third subsets of stator modules comprising a core having at least one winding disposed thereon;
- and
- a drive unit attached to said housing and electrically connected to said first subset of stator modules, said drive unit configured to selectively provide electrical current to said first subset of stator modules.
