Stator Core Support Device for Damage-Free Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stator core manufacturing apparatuses face challenges in efficiently inverting stator cores without causing damage, such as curling or denting of laminated steel plates, due to excessive load application during the inversion process.
Innovation Solution
A stator core support device featuring two radially opposed support members with an inverting mechanism that rotates them simultaneously to reverse the stator core's orientation along its central axis, allowing axial movement while minimizing friction and impact, thus preventing damage by distributing force evenly and reducing kinetic friction.

Engineering Contradiction Analysis
1Productivity
If the stator core is vertically inverted using a conventional chuck, then the manufacturing efficiency is improved, but the stator core is likely to suffer damage such as curling, dent, or peel-off of laminated steel plates due to excessive load
Solution Approach 1:
The support device divides the stator core into multiple support regions using multiple support members (first and second support members) that contact different portions of the stator core. This segmentation distributes the inversion load across multiple contact points rather than concentrating it at a single chuck location, preventing damage to the laminated steel plates while enabling vertical inversion for improved manufacturing efficiency
Solution Approach 2:
The support members are designed with specific contact surfaces (first and second contact surfaces) that provide localized support at critical regions of the stator core. The first support member contacts the stator core at a first location while the second support member contacts at a second location, creating locally optimized support zones that prevent deformation during inversion without compromising overall structural integrity
2Stability of the object's composition
If the stator core is held firmly by the chuck during inversion, then the stator core remains stable, but excessive force is applied causing damage to the laminated steel plate
Solution Approach 1:
The support members are positioned and configured in advance to contact the stator core at optimal locations before inversion begins. The first support member is positioned to contact the stator core at a first location and the second support member at a second location, creating a cushioning effect that absorbs and distributes inversion forces beforehand, preventing direct transmission of excessive force to the laminated steel plates
Solution Approach 2:
The support device transitions from a static chuck configuration to a dynamic multi-point support system during inversion. The support members are arranged to accommodate the movement and orientation changes of the stator core during inversion, maintaining stable contact throughout the inversion process while adapting to changing force vectors, thereby preventing damage without sacrificing stability

AI summary
A stator core support device includes two support members that are radially opposed to a stator core such that a central axis of the stator core is interposed between the support members, and an inverting mechanism that inverts the two support members. Each of the support members has a radially opposed face that is radially opposed to the stator core, a first axially opposed face that is axially opposed to a first axial side of the stator core, and a second axially opposed face that is axially opposed to a second axial side of the stator core. While the inverting mechanism is inverting the two support members that hold the stator core, the stator core is moved in the axial direction relative to the two support members.
