Axial Flux Stator Modules Edge-to-Edge Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stators for axial flux electromagnetic machines are not compact due to gaps between unit portions, leading to increased weight, dimensions, and manufacturing complexity, with existing solutions either requiring additional support members or being costly and heavy.
Innovation Solution
A stator design where unit portions are arranged concentrically edge-to-edge with securing means on axial and lateral faces, allowing for a compact configuration and easy assembly, with removable or permanent securing methods such as screwing, snap-fitting, welding, or gluing, eliminating the need for additional support members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If unit portions are separated by notches and walls as in conventional designs, then manufacturing and assembly are simplified, but the stator becomes less compact with increased dimensions and weight
Solution Approach 1:
The stator is divided into modular unit portions that can be manufactured separately and assembled independently, allowing simplified production while maintaining compact final assembly through edge-to-edge arrangement
Solution Approach 2:
The securing means are integrated directly into the unit portions themselves rather than requiring separate support members, merging the fastening function into the existing modular components to eliminate additional parts and maintain compactness
2Ease of operation
If additional support members are used to secure unit portions, then assembly is facilitated, but the stator weight and cost increase
Solution Approach 1:
The securing means are combined with the unit portions themselves, integrating the fastening function into the modular components rather than requiring separate support members, thereby eliminating additional weight and cost
Solution Approach 2:
Each unit portion is self-contained with its own securing means, allowing it to be mounted independently without requiring external support structures or additional assembly components
3Ease of manufacture
If unit portions are arranged with intervals between them, then manufacturing is easier, but the stator dimensions and weight increase
Solution Approach 1:
The stator is segmented into manufacturable unit portions that are designed to fit together edge-to-edge, allowing easy production of each module while achieving compact overall dimensions through precise modular arrangement
Solution Approach 2:
The securing means are positioned at specific locations on each unit portion to provide localized attachment points, enabling compact edge-to-edge arrangement while maintaining manufacturing simplicity through standardized modular design

AI summary
This invention relates to a stator for an axial flux electromagnetic machine, with the stator forming a ring (1) having two substantially circular faces (1a, 1b) connected by a thickness comprising windings (3) regularly distributed in the ring (1). Each winding (3) is carried by a unit portion (4) having a core (5) around which the winding (3) is wound. The unit portions (4) are arranged concentrically edge-to-edge with respect to one another and have securing means (12, 12a, 14) with a support member (6) which is part or not of a casing housing the ring (1) carried either by axial and lateral faces of each unit portion (4) edge-to-edge or by at least one upper or lower face of with each unit portion being part of a substantially circular face.
