摘要： 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.

摘要： A rotor of a rotating electric machine includes a cylindrical rotor core, a plurality of coil slots provided on an outer periphery of the rotor core along a rotor axis direction, rotor coils disposed in the coil slots by laminating a plurality of field conductors through an insulation material, a rotor wedge disposed at an opening end portion of the coil slot so as to support the rotor coil, a coil ventilation duct formed in the coil slot so as to pass through the rotor coils, the rotor wedge and the insulation material, and sub-slots provided at bottom portions of the coil slots so as to be communicated with rotor core ends and the coil ventilation ducts. In such a rotor of a rotating electric machine, the coil slot, the sub-slots and the coil ventilation duct constitute a cooling gas channel for distributing a cooling gas to thereby cool the rotor coils. A depth in a diameter direction of each sub-slot from the rotor coil end to a nearest coil ventilation duct is larger than a depth of the sub-slot at a portion near a center of the rotor core.
