Abstract (en)
[origin: EP0337290A2] A commutator for an electric motor and a reinforcing ring therefor are produced in such a manner that the reinforcing ring has an inner supporting ring and outwardly directed projections with which an anchorage to the commutator laminates is produced. Such a reinforcing ring is easy to install and creates a high load capability. It can additionally be completed to form a reinforcement which also comprises an inner bush. In the case of a design consisting of insulating material, such an inner bush produces a double insulation and allows a precise force fit to be specified for pressing onto a motor shaft. <IMAGE>
