Abstract
For obtaining an electric rotating machine being constructed cheaply, while cooling capacity at the end portions of the rotor coils can be improved, and being small in the size and large in the capacity, with superior reliability thereof, in an electric rotating machine, within which a coolant fluid is circulated, wherein coil support members 13 are positioned at a distance therebetween, in a space defined between the end portions 12B of the plural rotor coils, each of the coil support members 13 is formed with two (2) insertion portions 13a extending in a radial direction and a connector portion 13b connecting therebetween, as one body and in an about “H” shape in the cross-section, thereby forming spaces 13c, each of which faces the end portion 12B of the rotor coil, at both sides of the connector portion 13b.
