ABSTRACT:
To enhance the cooling of an alternator stator, each end of the stator including the end turns of the stator wires is enclosed in a fluid tight assembly containing a matrix of ceramic balls. Since the stator wires are contained in slots in the stator laminations, cooling of the stator wires is facilitated by the cooling fluid flowing parallel to the stator wires in the stator slots from one end assembly to the other end assembly with the ceramic balls assuring uniform coolant flow through the stator slots. An external fluid passage contains a pressure drop orifice resulting in a pressure differential between the end assemblies so that a certain proportion of the cooling fluid will flow through the stator slots.
