METHOD FOR MANUFACTURING WINDING COIL OF ELECTRIC MACHINE

摘要

The object of the invention is a method for manufacturing a coil of an electric machine from flat cable (2) and an electric machine that includes the coil. The coil includes flanks (8, 10) that are located in the slots of the electric machine and outside of the slots there are coil ends (12, 14) that form the end parts of the coils. The method according to the invention includes following phases: a flat cable (2) is winded to a coil billet (6) in which winding circles are in same planes and in which there are two parallel straight coil flanks (8, 10) on the opposite sides of the coil. The parallel coil flanks (8, 10) are then bend towards each other in substantially straight angle when compared to the winding plane.
