A process for the preparation of a rotor - waves / sleeves - unit and the rotor - waves / sleeves - unit

摘要

Disclosed is a method for producing a rotor - waves / sleeves - unit for brushless dc motors and a rotor - waves / sleeves - unit described. In the method, by means of a spraying process the rotor - sheet metal - package of the unit with the associated shaft or a sleeve connected. In this case, a both components made of the conveyor of the plastic hub, which leads to a considerable reduction in weight of the units. The plastic hub can, for example, in the cross section of double - t - shape and have reinforcing ribs.
