Core for Stationary Electromagnetic Apparatus - A simplified explanation of the abstract

This abstract first appeared for US patent application 18203397 titled 'Core for Stationary Electromagnetic Apparatus

Simplified Explanation

- The patent application describes a core for a stationary electromagnetic apparatus. - The core is made of amorphous metal thin strips that are laminated together. - The core is designed to reduce noise generated by magnetostrictive vibration. - A holding member is used to hold the laminated body in place. - The width of the holding member is equal to or greater than the width of the laminated body in the laminating direction. - This design helps to suppress compressive stress load in the laminating direction, reducing noise while maintaining the space factor of the amorphous core.


Original Abstract Submitted

Provided is a core for a stationary electromagnetic apparatus, in which a compressive stress load in the laminating direction of amorphous thin strips that form an amorphous core is suppressed so that noise generated by magnetostrictive vibration is reduced while maintaining a space factor of the amorphous core. The core for a stationary electromagnetic apparatus according to the present invention includes: a laminated body formed of amorphous metal thin strips; and a holding member that holds the laminated body , in which a width b of the holding member is equal to or more than a width a of the laminated body in a laminating direction.
