| Abstract: | The reasons of stator core loose and tooth fracture of core lamination were analyzed, in which not only the static state was considered, but also, the variation of the used materials by influecing of mechanical force, electromagnetic force and heat expansion were considered too, and detailed calculation was accomplished. Then the rational explanations of present problems were obtained. |
