Rotor arrangement for e.g. claw pole motor, has magnet carrier for accommodating permanent magnets, where carrier is manufactured as injection molding component and directly sprayed on outer ring of ball bearing

摘要

The arrangement has a plastic magnet carrier (10) for accommodating permanent magnets (16), where the carrier is manufactured as an injection molding component. The magnet carrier has a cylindrical shape and is formed in magnet carrier slots (14), which are opened to an outer circumference of the magnet carrier. The permanent magnets are fixed in the slots in an axial direction by material deformation at the magnet carrier or by an additional fastening unit. The magnet carrier is directly sprayed on an outer ring of a ball bearing (12).
