ABSTRACT OF THE DISCLOSURE A method of forming and mounting a fan for use in cooling an annular group of stator winding end turns in a dynamoeleatric machine. The method comprises the steps of forming in an annulus of a plurality of cooling means which remain disposed generally in the plane of the annulus, and the annulus is then secured to an end ring of a rotatable assembly for the dynamoelectric machine. Thereafter, the cooling means is deformed from the plane of the annulus to extend over the outer periphery of the stator end turns. The method of making a dynamo- electric machine and the method of effecting improved concentricity of a fan in the manufacture of a dynamo- electric machine are also disclosed.
