Claim:
1. A method for producing rotating electrical machines having a motor coil produced in a cantilevered manner for motors or generators, wherein the motor coil already surrounds a magnetic inner part during the manufacturing process, and this is also used as an aid for coil shaping during the production of the motor coil, comprising: a first step, in which the motor coil is wound in a stepwide process between two end faces over the magnetic inner part and completely surrounds the magnetic inner part, and a second step, combined with the first step, in which shaping of the motor coil is carried out by compressing winding wires by moving a shaft with a surface of the magnetic inner part against an inner side of the motor coil, wherein the shaping of the motor coil is carried out during the winding process by eccentrically rolling off of the surface of the magnetic inner part on the inner side of the motor coil and an abutment against an outer side of the motor coil, and a third step, in which the compressed motor coil is baked by applying heat.
