Abstract
The commutator of the motor is made up of three parts assembled coaxially and insulated from one another. Each part is connected to one of the windings of the rotor. The parts are blanked from a sheet of metal, preferably silver, with a flat annular zone, an inner lug, and radial fingers which are subsequently all bent at a 90.degree. angle at the same side of the annular zone. The parts are fitted into each other in such a way that the fingers of the different parts are seated around the circumference of the commutator.
