Abstract (en)
[origin: EP0457126A2] A commutator for an electric motor or generator having laminates which are distributed symmetrically with respect to a commutator axis on the circumference or on an end side and which are supported in an insulating material base body, the commutator having a central opening, whose diameter is designed to form a push fit onto the shaft of the electric motor or generator and which is stiffened by means of a bush element of higher strength to absorb the seating and pressing on forces, is designed in order to achieve simpler and cost-effective production, easier and non-critical handling when being pressed onto a motor shaft, and high robustness and long life such that the bush element has an internal diameter which is larger than the diameter of the opening and such that the bush element is covered internally by a layer of insulating material. <IMAGE>
