ELECTRIC MOTOR AND INSERT MOLDING METHOD FOR LAMINATE CORE

PROBLEM TO BE SOLVED: To make a laminate-directional thickness of a laminate core constant without being influenced by a manufacture error and the like, and to adjust balance of the laminate core.SOLUTION: A laminate core 40 includes a laminate 41 formed by laminating a plurality of core members 40a and an insulator 42 for covering an outer surface of the laminate 41. A resin thickness variation part 45 is provided to a laminate-directional end face 43a of the laminate 41, the resin thickness variation part 45 absorbs a laminate-directional size error of the laminate 41 formed by laminating the core members 40a to make the laminate-directional thickness of an insert-molded laminate core molding constant, and the resin thickness variation part 45 is provided with a resin thinned part 49 formed by thinning a resin material.
