<p>In order to increase the power of a motor, it is necessary to efficiently cool the motor, and there is adopted a construction for cooling the interior of the motor with clean air. Namely, the cooling construction is of such an arrangement that a piping (18) communicating with the interior of the motor to circulate therein the air is provided outside a motor casing (14), liquid is led out to the outside from a flow path (34) of the liquid for cooling a stator (32), made to flow into a piping (20) for heat exchange, which passes through the said piping (18) and returned to the said flow path (34) to cool the air circulating in the piping (18). <IMAGE></p> |
