Title:
MAGNETIC ELEMENT AND MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/142313
Kind Code:
A1
Abstract:
The present invention provides a magnetic element, comprising a plurality of magnetic units. The plurality of magnetic units is arranged in sequence; a groove and a connecting portion are provided between adjacent magnetic units; the grooves are used for blocking an eddy current path; the connecting portions connect adjacent magnetic units; and the connecting portions are connected to the grooves and prevent the grooves from completely penetrating through adjacent magnetic units. The connecting portions and the magnetic units are made of the same material and are integrally formed, such that the overlapping and bonding processes are omitted, the production efficiency of the magnetic element is effectively improved. Meanwhile, when it is ensured that the magnetic element has corresponding structural strength, the grooves for blocking the eddy current path are provided, such that the implementability is realized, and the applicability is improved.
