Solution Overview

Problem

Conventional magnetic flux shields for generators are costly due to their integrated fabrication, which increases production and assembly costs, especially when dealing with complex structures, and they do not easily accommodate varying generator specifications.

Innovation Solution

A split structure flux shield with radial, left-right, or top-bottom symmetry, made of copper or aluminum, with intervals between split structures ranging from 1 to 100 mm, allowing for easy fabrication, assembly, and adaptation to different generator shapes and specifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If magnetic flux shield plates are fabricated in an integrated manner to fully cover both ends of the generator, then magnetic flux shielding effectiveness is improved, but production cost and material cost are increased

Engineering Contradiction:
Improvemagnetic flux shielding effectivenessVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The flux shield is divided into multiple separate plates (first flux shield plate and second flux shield plate) that can be manufactured independently and then assembled together. This segmentation allows each plate to be produced more easily and at lower cost while collectively providing the same shielding effectiveness as a single integrated shield.

Inventive Principle:
