Abstract

PURPOSE:To enable to uniformly cool a rotor core and a rotor coil by providing an interference preventing member for cooling gas at a position where a ventilating duct radially penetrating the core and an air hole penetrating in the axial direction intersect with each other. CONSTITUTION:A radially penetrating ventilating duct 5 is provided at the axial center of a rotor core 2, an air hole 6 is axially penetrating the core 2, and cooling gases 7, 8 are respectively passed through the duct 5 and the hole 6. In this case, a interference preventing member 12 for cooling gas is mounted at the position where the duct 5 and the hole 6 intersect so that the gases 7, 8 may independently flow. In this manner, the air resistance can be reduced, and the entire rotor can be uniformly cooled.
