摘要:
A first laminate layer block having a bolt fixing unit laminated/fixed by caulking a plurality of steel plates having lug metals protruding diametrically and a second laminate layer block laminated/fixed by caulking a plurality of steel plates not having lug metals are rolled and laminate on part of a steel plate, and are welded on the surfaces of their side surface in a laminate direction to be laminated and integrated. Accordingly, it is possible to prevent the axial force of the fixed bolt from being lowered due to thermal shock of a stator to decrease the occurrence of vibration or noise, and reduce vibration or noise by increasing the fixing levels of the stator and a case.
