摘要： An electrical machine comprises a polymeric housing (22) having a stator band (34), the polymeric housing (22) formed by a polymeric material and constructed to house components of the electrical machine, structurally support the electrical machine and react torque loads generated by the electrical machine;
a stator (18, 30) overmolded into and partially encapsulated by the stator band (34), the stator (18, 30) including a laminated stator core (30) and a plurality of stator windings (20);
a rotor (14) in magnetic communication with the stator (18, 30);
a first endplate (36) integral with the polymeric housing (22);
and a second endplate (38), the second endplate (38) being a polymeric endplate (36, 38), the second endplate (38) including a plurality of ribs (72) and a metallic structure (61), wherein the electrical machine is constructed as an industrial electrical machine.

摘要： 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).
