Abstract

Various embodiments include an electrical insulation system for an electric motor comprising: a laminated core having slots and wire windings; an surface electrical insulation in the slots surrounding individual wires with a potting compound; and an absorbent material between the individual wires and within the wire winding bounded by surface insulation material. The absorbent material took up liquid impregnation resin during the manufacturing process. The liquid impregnation resin has cured and now forms the potting compound.
