Radial Magnetic Circuit Assembly for Magnet Repulsion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies face difficulties in assembling and processing radial magnetic structures due to repulsive forces between magnets, leading to increased processing complexity and costs.
Innovation Solution
A radial magnetic structure assembly is designed with a magnetic central column, lower and upper ring members made of non-metallic materials, and tile-shaped magnets arranged uniformly on a limit step. The assembly method involves sleeving the ring members to limit radial displacement and secure the magnetic sheets to the magnets, effectively managing repulsive forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If radial magnetic structure is assembled using traditional methods, then magnetic field uniformity is improved, but assembly difficulty increases and processing cost rises due to repulsive forces between magnets
Solution Approach 1:
The patent applies preliminary action by pre-assembling the tile-shaped magnets onto the magnetic central column with limit steps before attaching the upper and lower magnetic sheets. The limit steps are预先 designed to position the magnets correctly, and the non-metallic ring members are prepared in advance to facilitate assembly by reducing repulsive force interference during the bonding process.
Solution Approach 2:
The patent uses non-metallic ring members as intermediary components between the tile-shaped magnets and the magnetic sheets. These ring members serve as mediators that reduce the repulsive magnetic forces during assembly, allowing the magnets to be properly positioned and bonded without direct contact between opposing magnetic poles, thus facilitating the assembly process while maintaining magnetic field uniformity.

AI summary
A radial magnetic circuit assembly device and an assembling method. The radial magnetic circuit assembly device comprises a magnetic center column (40), a lower collar (50), and an upper collar (60). The magnetic center column (40) comprises a large-diameter segment (41) and a small-diameter segment (42) that are sequentially connected and form limiting steps (43) for the uniform circular distribution of tile-shaped magnets (30). The lower collar (50) is sleeved outside the tile-shaped magnets (30) in a direction from the large-diameter segment (41) toward the small-diameter segment (42) and is used to limit a radial displacement of the tile-shaped magnets (30). The upper collar (60) is sleeved in a direction from the small-diameter segment (42) toward the large-diameter segment (41) and presses an upper axial magnetic sheet (10) and a lower axial magnetic sheet (20) closely against the upper axial side and the lower axial side of the tile-shaped magnets (30) respectively for attachment. In the assembly process, the tile-shaped magnets (30) are limited in the radial direction and the axial direction by the lower collar (50) and the upper collar (60) respectively, thereby effectively reducing a processing difficulty and improving production efficiency.
