Abstract:
The objective of the present invention is to suppress unevenness in cooling state when cooling a generator motor using a cooling medium. Thus, a generator motor cooling structure (100) contains: a first duct (32) that is provided to a flange (12) of the generator motor, extends towards the rotational central axis (Zr) of an input/output shaft (16) housed within a first housing (11), opens at the input/output shaft (16) side, and has a throttle section (35) partway along the duct; and a second duct (33) that is provided to the flange (12), extends towards a rotor (20) attached to the outside of the input/output shaft (16) after branching from the first duct (32) at a position to the outside in the radial direction of the input/output shaft (16) from the throttle section (35), and opens at the rotor (20) side.
