Patent ID: 7960878

Claim:
An electric rotating machine comprising: a rotor having a plurality of magnetic poles formed at a periphery thereof such that magnetic poles of different polarity alternate circumferentially; a stator core having a plurality of slots formed along a circumferential direction thereof so as to face said periphery of said rotor and have a depth direction which coincides with a radial direction of said stator core; a stator winding constituted by a plurality of coils each having in-slot portions housed in said slots and turn portions forming a coil end projecting from said stator core in an axial direction of said stator core at each of axial ends of said stator core, each of said turn portions connecting two of said in-slot portions adjacent in said circumferential direction outside said slots; and a cooling liquid feeding function of applying cooling liquid to said coil end; wherein said stator winding includes crossover portions each of which electrically connects ends of two of said coils through which currents in the same phase flow respectively, said crossover portions being arranged so that at least some of said crossover portions overlap one another in said radial direction, and so that at least some of said crossover portions overlap one another in said axial direction, so that said crossover portions form a wall extending from said coil end in said axial direction, said cooling liquid feeding function applying said cooling liquid to at least one of said crossover portions.
