Armature Segment Pressing for Uniform Conductor Joint Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing armatures face challenges in achieving a uniform pressing force across conductor segments with varying height positions, leading to suboptimal joint quality between conductor segments due to manufacturing errors.
Innovation Solution
The use of independently movable pressing jigs for each segment conductor allows for precise and sufficient pressing force application, regardless of variations in position, ensuring improved joint quality between the first and second segment conductors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a flat-surface-shaped pressing jig is used to press multiple coil end parts simultaneously, then the pressing operation is simple and efficient, but insufficient pressing force is applied to segment conductors with low height positions, deteriorating joint quality
Solution Approach 1:
The pressing jig is divided into multiple independent pressing units, each capable of independently pressing a specific coil end part. This segmentation allows each pressing unit to adapt to the actual height position of the target segment conductor, ensuring sufficient pressing force is applied to all conductors regardless of height variations, thereby resolving the contradiction between pressing efficiency and joint quality
Solution Approach 2:
Each pressing unit is designed with adjustable pressing force characteristics tailored to the specific requirements of the local coil end part it presses. This local quality approach ensures that each pressing unit can deliver the optimal pressing force for its target conductor, maintaining high joint quality across all segment conductors while preserving the efficiency of simultaneous pressing operations

AI summary
The method for manufacturing an armature includes a step of independently pressing pressing-target segment conductors by a plurality of pressing jigs disposed for each of the pressing-target segment conductors, such that the plurality of pressing jigs are movable relative to each other, at least either one of first segment conductors and second segment conductors serving as the pressing-target segment conductors.
