ABSTRACT:
With a salient pole dynamoelectric machine embodying this invention, the inner peripheral wall of the stator is covered with a partition wall which is formed of a cylindrical base wall spaced from the inner peripheral wall of the stator at a prescribed distance and annular rims formed at both ends of the cylindrical base wall. Air inlet chambers each containing a blower and air outlet chamber each containing an air cooler are alternately arranged in a circumferential direction on the outer peripheral wall of the stator. Application of the partition wall enables to stator and rotor both be separately cooled by the corresponding exclusive blowers, thereby ensuring the efficient cooling of the dynamoelectric machine, and reduction in cooling motive power and blower pressure.
