<p>A rotary electric machine includes: a stator, a rotor and rotor fans contained in a closed type frame. The cooling gas is circulated in the frame by the rotor fans and warmed as a result of heat exchange with the stator and the rotor is cooled by a gas cooler. A heat pump is adapted to use cooling water or ambient air as high temperature heat source and liquid coolant as low temperature heat source. A liquid coolant circulation system for supplying liquid coolant to the heat exchange section of the gas cooler is provided. The liquid coolant is cooled by the heat pump and is supplied to the heat exchange section of the gas cooler by means of the coolant circulation system.
