摘要: A magnetic component and a manufacturing method thereof are provided. The magnetic component includes a magnetic core, a first winding set and a second winding set. The magnetic core is made of a magnetic powder material and includes two connecting portions connected through three magnetic columns to form a first side and a second side opposite to each other. The first winding set and the second winding set are made by a flat conductive body, and spaced apart on the middle magnetic column at a distance. The first winding set includes two first conducting portions connected through a first horizontal portion. The second winding set includes two second conducting portions connected through a second horizontal portion. The first horizontal portion and the second horizontal portion are exposed to the first side, and the two first conducting portions and the two second conducting portions are extended to the second side.

摘要: An object of the present invention is to improve a mechanical strength and to ensure a low magnetic loss without using a supporting member even when amorphous ribbons are used for an inner core. To attain the object, a stationary induction apparatus core of the present invention includes an inner core formed from the amorphous ribbons and outer cores formed from silicon steel sheets, the outer cores being disposed on two sides of the inner core in a depth direction as opposed to a standing direction of the inner core in such a manner as to sandwich the inner core therebetween.

摘要: The present invention discloses a power inductor encapsulated through injection molding. The power inductor comprises a coil winding, a soft magnetic ferrite middle column inserted in a middle of the coil winding, and a magnetic powder glue for encapsulating the coil winding and the soft magnetic ferrite middle column through injection molding. The power inductor is square and meets L≧W and 2rc>0.4×2W, wherein a section width of the soft magnetic ferrite middle column perpendicular to a height direction of the inductor is 2rc, a length of the power inductor is 2L, and a width of the power inductor is 2W. According to the present invention, a balanced direct-current resistance and a direct-current superposition saturation characteristic can be obtained, and the direct-current resistance is greatly decreased while an excellent direct-current superposition saturation characteristic is ensured.
