Abstract (en)

[origin: WO2014032154A2] The present invention refers to the step of closing the side flaps of the polar bases of dynamo-electric machines stators which incorporates the manufacturing process of dynamo-electric machine stator. In general, said step of closing the side flaps of the polar bases of dynamo-electric machines stators provides for the deformation of the ends (4) of the same polar bases of a shaft (11, 12) of the stator (1) from rotating displacement imposed by at least one roller (5, 6) capable of being circumferentially moved in the clockwise and anti-clockwise directions. It is further disclosed a system for deformation of dynamo-electric machine stator, which is capable of performing the aforementioned step of closing the side flaps of the polar bases of dynamo-electric machines stators.
