Electric machine component is a component 7 made before the ET-equipped (6) for transmission, the method of manufacturing the electric fatigue excellent mechanical component 7 life is disclosed. The method of the present invention, by applying the isostatic stress in the inner surface (2a) of the ring base material (2) to try to form a motor drive (6), the electric parts in the inner surface (2a) of, by cold forging, the ring base material 2 forming a motor drive (6) for the electric, and enlarge the inner diameter of the ring base material 2 other than the motor drive (6). Accordingly, the ring base material (2) construction of the steel the non-metallic inclusions and a ring-shaped machine parts (7) the interface state between the mother phase of the steel is improved with a motor drive (6) of the excellent electric fatigue life in diameter contained in this It is prepared.
