Commutator and method of manufacture thereof

摘要

A commutator includes a hub, a segment set having armoring and an inner cover surface, and insulation arranged between the hub and the segment set. The segment set is forcefittingly coupled with the hub by support forces directed toward its inner cover surface. The result of this arrangement is that the hub and the insulation are radially prestressed by tension forces caused by the armoring of the segment set.
