Split-Body Electromagnet Structure for Easier Coil Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnets with integrated housing and iron core structures are inconvenient for coil winding and are not suitable for restricted spaces, such as in electromagnetic clutches.
Innovation Solution
A split-type electromagnet design where the housing and iron core are of a split type, allowing the iron core to be fixed within the housing after coil winding, and featuring a cylindrical or sector-shaped ring housing configuration for enhanced flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the housing and iron core are of an integrated-type structure, then the structural strength is improved, but the winding of the coil around the iron core becomes very inconvenient
Solution Approach 1:
The electromagnet is divided into separate housing and iron core components that can be assembled after coil winding. The housing includes a housing body and a bottom plate that are connected together, allowing the iron core to be inserted and fixed after the coil is wound around it, thus resolving the contradiction between structural strength and coil winding convenience.
2Ease of manufacture
If the housing is of a cylindrical shape, then the manufacturing simplicity is improved, but the adaptability to restricted spaces becomes poor
Solution Approach 1:
The housing is segmented into a housing body and a separate bottom plate that can be connected via threaded holes and screws. This modular design allows the electromagnet to be configured in different shapes (cylindrical, sector-shaped ring, rectangular ring) while maintaining manufacturing simplicity, enabling adaptation to restricted spaces such as around meshing gears in electromagnetic clutches.

AI summary
The present disclosure discloses a split-type electromagnet, wherein the split-type electromagnet comprises a housing and an iron core, the housing and the iron core are of a split type, wherein the iron core is fixed within the housing after the coil has been wound on the iron core, and the housing is a cylindrical body or an ellipsoidal body or a cross section of the housing is a sector-shaped ring or a rectangular ring. Compared with the integrated type of the housing and the iron core in the prior art, the winding of the coil of the electromagnet is more convenient. Furthermore, when the cross section of the housing of the electromagnet is a sector-shaped ring, a plurality of electromagnets are combined to form an electromagnet unit, and when the space is restricted, the electromagnet unit may be used to complete the electromagnetic attraction.
