Abstract:
1. A compact, high power, power conversion apparatus comprising: a rotor comprising a cylindrical casing, and a predetermined number of permanent magnets disposed on the casing, the rotor being adapted for rotation about the axis of the casing; a stator comprising a core and a plurality of sets of conductive windings, each set including a predetermined number of individual conductive windings and associated with an electrical phase, and each set of individual conductive windings associated with an electrical phase is further partitioned into phase subgroups; a respective set of collecting conductor arcs respectively associated with each phase subgroup, each individual conductive winding of the respective phase subgroup being electrically connected in parallel to the associated collecting conductor arc; and a coolant flow path directing coolant into contact with the stator windings; the respective collecting conductor arcs being disposed in the coolant flow path electrically isolated from each other and spaced apart from each other and from the windings; wherein the collecting conductors each comprise, for each electrical phase, a respective set of a predetermined number of electrically isolated conductive arcs.
