摘要： A rotating electrical machine (10) includes a stator (30) equipped with a stator winding (31), a rotor (20) arranged to face the stator, a housing in which the stator and the rotor are disposed, and a coolant supply unit (70). The coolant supply unit is located vertically above the stator and the rotor in the housing in a condition where the rotating electrical machine is mounted in place. The coolant supply unit works to deliver liquid coolant into the housing. A coolant guide (A2, 83) is provided to direct the coolant, as supplied from the coolant supply unit, into an air gap between the stator and the rotor in the housing.
