Abstract

A retainer in the stator of an electrical machine holds a plurality of stacked stator laminations in compression at an inner diameter of a stator core. The plurality of laminations have a central aperture and a plurality of teeth circumferentially spaced about the central aperture. The plurality of stacked laminations forms a contiguous stator core with a central aperture for housing a rotor and stator winding slots extending from one axial face of the stator core to an opposite axial face of the stator core. The retainer is adapted to be fitted in the stator slots adjacent the windings and adjacent the central aperture. The retainer extends from one axial face of the stator core to the opposite axial face of the stator core. The retainer has opposite longitudinal ends abutting the axial opposite faces of the stator core that hold the laminations in compression.
