Cooling of stator windings

An arrangement for cooling an electric motor's stator winding coil is described. One area of a conductor insulation is removed to expose the copper conductor. The conductor is wound into a coil with bared, exposed conductor areas facing inward. The vertical edges of a slot or recess in an iron stator are lined with electrically insulating paper. A thermally conductive electrically insulating, ceramic substrate is bonded to the floor or base of the slot. The coil is inserted within the slot over the ceramic substrate with the exposed conductor facing and contacting the ceramic substrate. The coil is bonded to the ceramic substrate by thermally conductive and electrically insulative epoxy that fills the voids between the two. Heat flows from the conductor, through the bared copper surface, into the ceramic and the iron core stator with little resistance. A ceramic strip can be used alone or with copper traces bonded to the ceramic or conductor bared surface. Using a thermally conductive epoxy bond reduces resistance due to epoxy smear and reduces thermal resistance of the heat transfer path.
