Abstract
A motor-cooling structure is configured to cool a motor by using cooling oil. The motor is housed in a motor case. The motor-cooling structure includes a supply-port operator and a discharge-port operator. The supply-port operator is capable of opening and closing a cooling-oil supply port provided in a first wall of the motor case. The supply-port operator is configured to make an opening ratio of the cooling-oil supply port greater when a rotary shaft of the motor is stationary than when the rotary shaft is rotating. The discharge-port operator is capable of opening and closing a cooling-oil discharge port provided in a second wall of the motor case. The discharge-port operator is configured to close the cooling-oil discharge port when the rotary shaft of the motor is stationary.
