Abstract: PURPOSE:To minimize the fall or twist of stator cores, by a method wherein stator cores are laminated in number integer multiple of two or more times as much as a required laminate thickness and heat-treated and are then divided into pieces each having the required laminate thickness. CONSTITUTION:Iron cores 1 are formed by means of blanking. The iron cores 1 have caulking projections 2, respectively, which fit with each other in blanking. The iron cores 1 are laminated, and the caulking projections 2 are fitted with each other and caulked to form a stator core 3. Then, the stator cores 3 are laminated in number integer multiple of two or more times as much as a required laminate thickness and heat-treated. After the heat treatment, the stator cores 3 are divided into pieces each having the required laminate thickness. The divided stator core 3 receives a winding to reach completion. According to this method,the twist of each core due to the heat treatment is absorbed by increasing the laminate thickness, so that the fall or twist of the stator iron cores is minimized.
