ABSTRACT:
The invention prevents a temperature in an end portion of a stator iron core from becoming excessively high due to a heat generated in the end portion of the stator iron core of a turbine generator. In a dynamo-electric machine provided with a stator constituted by a stator iron core, a stator iron core pressing member and a stator coil, a rotor constituted by a rotor iron core, a rotor coil and a holding ring, and a baffle plate arranged in an inner diameter side of an end portion of the stator iron core and distributing a cooling medium cooling an inner side of the machine, the baffle plate is provided for forming a flow of the cooling medium along an inner periphery of the stator iron core pressing member and/or an inner peripheral surface of the end portion of the stator iron core.
