Reactor Fixture with Axial Protrusions to Suppress Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reactor designs with outer peripheral iron cores and plate-like members connected by rod-like members often result in bending of the plate-like members, leading to insufficient fixing of iron cores and generation of vibration and noise due to gaps between the iron cores and the plate-like members.
Innovation Solution
A reactor design featuring a core main body with outer peripheral iron core portions, iron core coils, and a fixture that includes plate-like members with axial protrusions, which are connected by rod-like members passing through the outer peripheral iron core, preventing bending and ensuring firm holding of the iron cores without generating vibration or noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plate-like members are rigidly connected by rod-like members, then the structure appears stable, but the plate-like members bend and gaps form between iron cores and plate-like members
Solution Approach 1:
The plate-like member is segmented into a first plate-like member and a second plate-like member that are disposed at different locations. This segmentation allows each plate-like member to independently contact and fix different iron cores, preventing bending while maintaining fixing precision. The rod-like members connect these segmented plates, distributing structural loads and preventing deformation that would create gaps.
Solution Approach 2:
The rod-like members act as intermediaries that connect the plate-like members to the iron cores and to each other. By passing through the plate-like members and iron cores, the rod-like members provide a mechanical linkage that prevents bending of the plate-like members while maintaining precise positioning. This intermediary connection ensures that the plate-like members remain stable without forming gaps.
2Ease of manufacture
If plate-like members are connected without protrusions, then manufacturing is simpler, but vibration and noise occur due to insufficient fixing
Solution Approach 1:
The plate-like members are provided with protrusions at specific local positions that extend in the axial direction. These local protrusions make contact with the iron cores to provide additional fixing force, preventing vibration and noise. The protrusions are strategically positioned to contact the iron cores without requiring complex manufacturing processes, thus maintaining ease of manufacture while eliminating harmful vibrations.
3Ease of operation
If gaps are formed between iron cores and plate-like members, then assembly is easier, but insufficient fixing occurs causing vibration and noise
Solution Approach 1:
The fixture structure allows for dynamic adjustment during assembly where the plate-like members with protrusions can adapt to the positioning of iron cores. The rod-like members provide flexibility in the assembly process while ensuring that when assembled, the protrusions make contact with the iron cores to eliminate gaps. This dynamic structure maintains fixing reliability without compromising assembly ease.

Function Achieved in This Case
The design effectively suppresses vibration and noise by firmly holding the iron cores, ensuring stable operation of the reactor while maintaining a reduced weight and cost-effective magnetic field configuration.

AI summary
Provided is a reactor having a core main body that includes an outer peripheral iron core, at least three iron cores, and coils. Between the iron cores adjacent to each other, a gap being magnetically coupled is formed. The reactor includes a fixture that fixes both end portions of the at least three iron cores together by passing through an interior of the outer peripheral iron core in a region between the outer peripheral iron core and the gap. The fixture includes plate-like members disposed on both end faces of the core main body and includes rod-like members that connect the plate-like members to each other by passing through the interior of the outer peripheral iron core. The plate-like members each include a protrusion extending axially inward of the core main body.
