Abstract
In a magnetic core including a core assembly having a structure that multiple thin strip blocks are arranged, the thin strip blocks being formed of multiple laminates of nanocrystalline thin strips made of a nanocrystal-containing alloy material, the thin strip block includes a fixedly joined portion in which the nanocrystalline thin strips adjacent to each other in a lamination direction are fixedly joined together. The fixedly joined portion may include side surfaces of the nanocrystalline thin strips and may be a laser welded portion.
Claims11
A magnetic core comprising:
- a core assembly including a plurality of thin strip blocks assembled together, each of the plurality of thin strip blocks being a laminated body formed of a plurality of nanocrystalline thin strips made of a nanocrystal-containing alloy material,
- wherein each of the plurality of thin strip blocks includes fixing portions in which the plurality of nanocrystalline thin strips are joined to each other in a lamination direction of the laminated body;
- wherein each of the plurality of thin strip blocks further comprises a body portion and a plurality of teeth extending radially and outwardly from an outer side surface of the body portion, and the plurality of teeth of the plurality of thin strip blocks are aligned with each other in the lamination direction of the laminated body;
- wherein the fixing portions are disposed on respective one side surfaces of protrusions in distal end portions of the plurality of teeth in a circumferential direction or disposed on respective outer side surfaces of the body portion positioned between two adjacent teeth of the plurality of teeth.
