Abstract:
1. A stator assembly comprising: (a) a stator core comprising laminated electromagnetic steel sheets and further comprising wire wound coils; (b) an over-molded insulator covering the stator core and being positioned between the stator core and the wire wound coils; wherein the over-molded insulator comprises a thermally conductive polymer composition having a thermal conductivity of at least about 0.6 W/mK; and (c) an adhesive component interfaced between the stator core (a) and the over-molded insulator (b); wherein the thermally conductive polymer composition comprises a base polymer and a filler material; and wherein the base polymer is selected from the group consisting of thermoplastic polymers and thermosetting polymers, and the polymer contains groups that are reactive with the adhesive component (c).
