WOUND CORE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18032519 titled 'WOUND CORE
Simplified Explanation
The wound core described in the patent application is made up of stacked polygonal annular grain-oriented electrical steel sheets with planar and bent portions that alternate in a longitudinal direction. The crystal grain size of the steel sheet in at least one bent portion is FL/4 or more, where FL is the average length of the planar portions.
- The wound core is made of polygonal annular grain-oriented electrical steel sheets with alternating planar and bent portions.
- The crystal grain size of the steel sheet in at least one bent portion is FL/4 or more, where FL is the average length of the planar portions.
Potential Applications

Unanswered Questions
How does the crystal grain size affect the performance of the wound core in electrical devices?
The crystal grain size in the bent portions of the steel sheets is mentioned as FL/4 or more, but the specific impact of this on the overall performance is not detailed in the abstract.
Are there any specific manufacturing processes required to achieve the desired crystal grain size in the steel sheets?
The abstract mentions the crystal grain size requirement but does not elaborate on the manufacturing methods needed to meet this criterion.
Original Abstract Submitted
This wound core is a wound core including a wound core main body obtained by stacking a plurality of polygonal annular grain-oriented electrical steel sheets in a side view, and the grain-oriented electrical steel sheet has planar portions and bent portions that are alternately continuous in a longitudinal direction, and in at least one bent portion, the crystal grain size Dpx (mm) of the grain-oriented electrical steel sheet is FL/4 or more. Here, FL the an average length (mm) of the planar portions.
