Abstract
A method is disclosed for manufacturing the winding coil of an electrical machine from flat wire. The coil can include coil sides fitted to a groove of an electrical machine and end sections which are left outside the groove and form a coil end. Flat wire can be used for winding a spool in which the coil rounds are in the same winding plane and in which there are two parallel straight coil sides on opposite sides. After this, the parallel straight coil sides can be bent towards each other essentially to the right angle in comparison to the winding plane.
