Summary:A stator assembly of an electric machine includes a stator core having a slot extending between a first end and a second end, where the slot includes a first slot exit at the first end and a second slot exit at the second end. Also, the stator assembly includes a plurality of windings, where one of the plurality of windings is disposed in the slot and extends from the first slot exit to the second slot exit, and where the plurality of windings includes at least one conductor and an insulation disposed around the at least one conductor. Further, the stator assembly includes a dielectric plate coupled to one of the first slot exit and the second slot exit and configured to suppress surface discharges on windings present at one of the first slot exit and the second slot exit to which the dielectric plate is coupled.
