Abstract

A silicon steel sheet stacking structure includes a main silicon steel lamination, a blocking silicon steel sheet, and a riveting blocking portion. The main silicon steel lamination includes silicon steel sheets stacking in a first direction. Each of the silicon steel sheets has at least one through hole. The blocking silicon steel sheet is disposed on the main silicon steel lamination. The blocking silicon steel sheet has at least one through hole. The riveting blocking portion is extended from the blocking silicon steel sheet and is raised above a surface of the blocking silicon steel sheet. The riveting blocking portion is configured to be compressed and generate a deformation, such that the riveting blocking portion pushes at least one magnet located in the at least one accommodating space to abut the at least one magnet against an inner surface of the at least one through hole.
