Rotating electrical machine having rotor and stator cooled by means of heat pipes

摘要: A polyphase induction motor having a rotor and stator, each heat pipes incorporated therein, is disclosed. The stator comprised of stack laminations radial slots therein which contain as well electrical conductors. are located in the extend axially to remote location beyond rotor. wicks twophase fluid coolant. also with outer periphery thereof. Heat and, like slots, stator. serve conductors exchangers for cooling Thus, all electrically interconnected by end rings at axial extremities two-phase However, because centrifugal force promotes condensate return within need not be used pipes. Cooling fins provided on those sections (condenser sections) thereby forming air exchangers. Moreover, moving act fan blades being proximate pipes, effectively form single-pass, forced-convection, exchanger.
