Problems solved by technology

[0002] At present, the insulating layers on both sides of the known electrical iron chips (such as silicon steel sheets, permalloy sheets or amorphous alloy sheets) only play an insulating role and do not contain magnetically conductive materials. The effective cross section of the iron chip needs to be subtracted from the total cross section of the insulating layer , resulting in the disadvantage of reducing the effective cross-section

Abstract

The invention relates to an electrical iron chip with an insulating layer containing a ferrite soft magnetic material. The electrical iron chip is characterized in that the ferrite soft magnetic material is contained in the insulating layer of the electrical iron chip; and the electrical iron chip is a silicon steel sheet, a permalloy sheet or an amorphous alloy sheet.

Description

technical field [0001] The invention relates to an electrical iron chip, in particular to an electrical iron chip whose insulating layer contains ferrite soft magnetic material. Background technique [0002] At present, the insulating layers on both sides of the known electrical iron chips (such as silicon steel sheets, permalloy sheets or amorphous alloy sheets) only play an insulating role and do not contain magnetically conductive materials. The effective cross section of the iron chip needs to be subtracted from the total cross section of the insulating layer , causing the disadvantage of reducing the effective section. Contents of the invention [0003] In order to overcome the shortcoming of the effective cross-section reduction caused by the total cross-section of the iron chip minus the cross-section of the insulating layer, the present invention proposes a method of adding a magnetically conductive insulating material into the insulating material, and coating the ...
