Abstract

A method for manufacturing a polymeric electrical machine includes manufacturing a stator (18, 30) including a laminated stator core (30) and a plurality of windings (20) including winding overhangs (48);applying a surface treatment to the stator (18, 30) core constructed to reduce defects at an interface between a polymeric material and the stator (18, 30) core and enhance adherence between the polymeric material and the stator (18, 30) core;mounting the stator (18, 30) onto a mandrel (108);inserting the stator (18, 30) into an electrical machine housing mold (100);molding an electrical machine housing (22) including a stator band (34) with an integral nondrive end endplate (36, 38), including overmolding the stator (18, 30) and winding overhangs (48) within the stator band (34);molding a drive end endplate (38), including forming polymeric ribs (72) in the drive end endplate (38) and overmolding a metallic structure (61) into the endplate (36, 38), the metallic structure (61) enhancing mechanical stiffness of the endplate (36, 38);installing a rotor (14) assembly (124) into the electrical machine housing (22);and installing the endplate (36, 38) onto the electrical machine housing (22).
