Abstract
An electrical machine comprises a polymeric housing 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 overmolded into and partially encapsulated by the polymeric housing, the stator including a laminated stator core and a plurality of stator windings, the stator windings including a winding overhang extending from the laminated stator core; a rotor in magnetic communication with the stator; and a cooling channel disposed within the polymeric material forming the housing and encapsulated by the polymeric material and positioned adjacent to the laminated stator core, wherein the cooling channel is constructed to pass a fluid for cooling the electrical machine.
