Abstract (en)
[origin: WO2014032153A2] The present invention relates to a method and a system of deformation of grooves of blades of stator of dynamo-electric type machines stator capable to promote a suitable opening of the housing channels (2) of the electrical conductors. More particularly, the present invention relates to a process and a system which comprise advance rods (7) radially distributed around said blade (1 ) and aligned with respective grooves formed between side flaps (5) of adjacent shoes (4), wherein the end of said advance rod (7) has a configuration appropriate for interacting with a respective rocker (8) pivoted in an articulating pin (8'), each one being provided with a deformation puncture (9) that causes the opening of the housing channels (2) of the electrical conductors; and at least one return disc (10) for driving said rockers (8) together with said punctures (9) to the initial position.
