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.
