Abstract

The subject of this invention is the way of forming the armature's commutator bars of the wire ends of the armature windings. The commutator consisting these and isolation material furthermore the processing method of these commutators will be discussed. The goal of this invention is that the armature parts of the rotating electric motors be more robust and reliable, equisolid both mechanically as well electrically. We achieve the above mentioned goal by forging the commutator bars from the armature windings wire end themselves and connect the wire pairs to each other with same forging and these formed commutator bars which are continuously connected to the armature winding separate from each other with an isolation ring that is fixed to the armature shaft. The commutator bars are embedded into the isolation or fixed on its surface with isolating ring.
