Abstract

Ein Kollektor für einen Elektromotor sowie ein Armierungsring hierzu wird in der Weise erstellt, daß der Armierungsring einen inneren Tragring und nach außen gerichtete Fortsätze aufweist, mit der eine Verankerung zu den Kollektorlamellen erstellt wird. Ein solcher Armierungsring ist leicht zu montieren und schafft eine hohe Belastbarkeit. Er läßt sich weiterhin zu einer Armierung vervollständigen, die auch eine innere Buchse umfaßt. Eine solche innere Buchse schafft bei Ausführung aus Isoliermaterial eine doppelte Isolierung und erlaubt es, einen präzisen Preßsitz für das Aufpressen auf eine Motorwelle vor­ zugeben. A collector for an electric motor and a reinforcement ring this is done in such a way that the reinforcement ring one inner support ring and outward projections, with which an anchoring to the collector slats is created becomes. Such a reinforcement ring is easy to assemble and creates a high resilience. He continues to admit a reinforcement that also complete an inner socket includes. Such an inner bush creates from execution Insulation material double insulation and allows one precise press fit for pressing onto a motor shaft admit.
