METHOD FOR PRODUCING ROTATING ELECTRICAL MACHINES

摘要

A method for producing rotating electrical machines having a motor coil produced in a cantilevered manner for motors or generators, wherein the coil already surrounds the inner part during the manufacturing process, i.e. is pre-assembled, and this is also used as an aid for coil shaping during the production of the coil, includes 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 inner part, a second step, in which the shaping of the motor coil is carried out by pressing the winding wires by moving the shaft with the surface of the inner part against the inner side of the motor coil, in particular by eccentrically rolling off of the latter and pressing it against an abutment, and a third step, in which the pressed motor coil is baked by way of applying heat. Also provided is a rotating electrical machine.

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