Abstract

PURPOSE:To facilitate laminating works of a motor core and to reduce the number of manufacturing steps by forming a concentric and circular steps on the outer and inner peripheries of a rotor core when the rotor and stator cores are concentrically punched and formed. CONSTITUTION:When a rotor core 4 and a stator core 3 are concentrically punched and formed of a strip steel plate, concentric and circular steps 8, 9 are pressed at least at one of the outer and inner peripheries of the rotor and stator cores 3, 4. The cores are laminated under the quidance of the steps 8, 9, the peripheries of the steps are caulked fixedly, thereby manufacturing a rotor 6 and a stator 5. In this manner, the laminating and fixing works of the cores can be facilitated, an air gap can be obtained without cutting the outer periphery of the rotor 6, thereby reducing the number of manufacturing steps.
