ABSTRACT:
An electrical machine (100) retained within a housing (116) in accordance with the invention includes a stator having a plurality of laminations (136) which are axially joined together to define a stator core (104) having a plurality of slots (106) which retain electrical windings (112) disposed circumferentially around the stator core which define poles; a first and second retaining mechanism (120) attached to the housing and having a radial projection extending radially inward from an inner cylindrical surface (118) of the housing with the retaining mechanisms having at least one axially projecting retainer (130) extending axially from a surface (132) of the radial projection (126, 128) facing a first or second axial end of the stator core and engaging the first and second axial end of the stator core.
