Abstract: An polyphase machine includes a stator having a plurality of parallel stator windings, a plurality of phase voltage terminals, each of the stator windings fastened to a corresponding phase voltage terminal, and at least one neutral terminal, each of the stator windings forming a common ground fastened to the neutral terminal. At least one of the stator windings is fastened to the corresponding phase voltage terminal or neutral terminal by a connection that does not involve a heat induced joining method. In an exemplary embodiment, the connection includes a lead wire protruding from the stator winding and terminated with a connector, such as a ring lug, fastened to the respective terminal with a mechanical fastener, such as a rivet or threaded rivet. A method for connecting stator windings in a polyphase machine is also provided.

Abstract: A method of assembling a substantially cylindrical motor casing having a plurality of cooling elements, includes the steps of forming a plurality of sections, each of the sections including a plurality of cooling channels extending therethrough in a longitudinal direction or a plurality of cooling fins extending therefrom, and each of the sections including an edge on each side thereof, each of the edges extending substantially parallel to the plurality of cooling channels or cooling fins; and connecting the plurality of sections together along their respective edges so as to form a substantially cylindrical shape from the plurality of sections.
