The invention discloses a fixing structure for a stator core and a machine base. The fixing structure comprises a locating rib and supporting blocks, wherein the locating rib is fixed between the stator core and the machine base; the supporting blocks comprise the multiple supporting blocks A for fixing the locating rib in the radial direction and the multiple supporting blocks B for fixing the locating rib in the tangential direction, and elastic elements are arranged between the supporting blocks A and the locating rib. The fixing structure can effectively protect the stator core and the machine base against buckling deformation caused by swelling of the stator core and can also reduce vibration of the stator core through rigidity of the machine base.
