ABSTRACT:
A collector for an electric motor or generator with lamellae, which are distributed symmetrically to a collector axis at the periphery or at a front face and which are embedded in a basic body of insulating material, the collector having a central opening, which is designed with respect to its diameter for a press fit on the shaft of the electric motor or generator and is reinforced by a bushing element of higher strength for absorbing the seating and pressing-on forces, is designed in the sense of being easier and less expensive to manufacture, being handled more readily and less critically while being pressed onto the shaft of a motor and being more robust and having a longer service life, so that the busing element has an internal diameter, which is larger than the diameter of the opening, and that the bushing element is covered on the inside by a layer of insulating material.
