<P>PROBLEM TO BE SOLVED: To increase the scattering amount of a cooling medium during low revolution of a rotary electric machine. <P>SOLUTION: A cooling structure of a rotary electric machine includes: oil reservoir parts 38, each of which is provided at an end plate 22; supply passages 36, each of which supplies a coolant flowed from a passage 30 in a rotor shaft 12 through a through hole 32 to the oil reservoir part 38; and discharge ports 48, each of which is a tip of a passage 40 communicating from the oil reservoir part 38 to an outer periphery of the end plate 22 and discharges the coolant in the oil reservoir part 38 toward a stator 16. The supply passages 36 are formed so that the number of the supply passages 36 becomes larger than the number of the discharge ports 48. <P>COPYRIGHT: (C)2013,JPO&INPIT |
