Commutation device, especially a commutator, and method for producing such a device

The present invention relates to a current reversal device, particularly a commutator, and to a process for production of such device. Such devices are employed in electric motors and current generators, for example, in tools powered by electricity, actuating drives, and fuel pumps. A commutator, having extremely exact geometrical dimensions and a long-time stability and being easy to produce, includes a pre-shaped, substantially cylindrical support body with a rotational axis. Electrically conductive commutator segments are fixed on the support body by fasteners arranged substantially between the commutator and the segments. The support body and the segments are provided with interacting structures to position and adjust the segments relative to the support body.
