Abstract
A rotating electrical machine cooling structure such that a cooling medium is supplied by a pump to a stator and rotor of a rotating electrical machine, thereby cooling the stator and rotor, includes a first passage that supplies the cooling medium from the pump to the stator, a second passage that supplies the cooling medium from the pump to the rotor, and a valve that regulates a flow of the cooling medium of the first passage and a flow of the cooling medium of the second passage, wherein a cooling state of the stator and a cooling state of the rotor are controlled by the valve.
