Patent ID: 8919685

Claim:
Method for manufacturing a cylindrical winding, comprising several turns of a wire and return loops, for slotless electrical machine according to the following steps: a) a winding head able to move according to three axes X, Y, Z, winds continuously a wire following a predetermined winding program around two sets of needles and on the external surface of a first cylindrical tube, two identical cylindrical bodies axially juxtaposed and axially and rotatably movable, are partially located inside said cylindrical tube and their remote ends being conical shaped surfaces said needles being located on the conical shaped end surfaces of said two identical cylindrical bodies b) after the achievement of the winding operation of all the electrical machine phases all around the 360° peripheral surface of said first cylindrical tube a second cylindrical tube is put around the achieved winding; c) said two sets of needles are taken away and the two cylindrical bodies are axially moved away.
