<p>PROBLEM TO BE SOLVED: To perform the downsizing by cooling a driver, in this driver for transmitting a part of rotational energy directly to the side of running drive, without changing all into power, when changing the driving power of an internal combustion engine into power through a generator. SOLUTION: A center core 1212 can be cooled enough by a refrigerant flowing in a forward passage hole 1212a and a backward passage hole 1212a. Furthermore, a part of the refrigerant is discharged to the periphery of a rotor core 1212, and it cools a rotor T's and rotor winding 1211, and enters a first air gap g1. Then, the refrigerant having entered the first air gap g1 enters a second air gap g2, passing through the above communication path (inner slit 1311c→slit overlapping part 1311e→outer slit 1311d). The refrigerant having entered this second air gap g2 cools the stator core 1412 and the stator coil of a stator 1410, and is collected by the gravity in the ground direction of a rotating machine from the end of the core, and is sent to a heat exchanger from the outlet of the refrigerant.</p> |
