Abstract
The main body of a rotary electrical machine is accommodated in a frame (1). A circulatory device (5) is provided that is rotated by a rotor (3) of said rotary electrical machine, in which there is accommodated cooling liquid (7) that cools at least the main body of the rotary electrical machine. The circulatory device (5) circulates said cooling liquid (7) to outside of the frame (1) by pump action. The cooling liquid (7) is accumulated by a reserve tank before being circulated within the frame (1). After the heated cooling liquid (7) is cooled in the reserve tank, this accumulated cooling liquid (7) is then caused to flow back into the frame (1) by the pressure difference.
