徴とする電動機の軸受冷却装置。 The shaft of the upright rotor is supported by a bearing, and the heat generated when the rotor rotates inside the stator is transferred to external air sent through the outlet air chamber by a fan attached to the rotor shaft. In a bearing cooling device for an electric motor in which heat is removed by internal air circulating in a stator frame cooled by heat exchange in a cooler, and in which the bearing is cooled by oil flow, one end portion an air duct that opens into the outlet air supply chamber and the other end opens to the atmosphere; a cooler that cools the oil flowing to the bearing within the air duct; and a flow rate of external air guided to the air duct. A bearing cooling device for an electric motor, characterized in that it is provided with a damper for adjusting.
