<P>PROBLEM TO BE SOLVED: To reduce variations in the cooling state of a coil of a stator of a generator motor when the coil of the stator is cooled. <P>SOLUTION: A cooling structure 100 of a generator motor 10 includes: a rotor holder 18; a rotor core 17; a first blade 40F; and a second blade 40R. The second blade 40R has a recessed cooling medium holding part 42R, which is provided at an outer peripheral part on the opposite side relative to the rotor core 17, opens at the radially inner side, and accumulates a cooling medium, and an outflow hole 41R radially penetrating through an outer peripheral part of the cooling medium holding part and flowing out the cooling medium accumulated in the cooling medium holding part 42R. <P>COPYRIGHT: (C)2013,JPO&INPIT |
