Rotor assembly for fractional horsepower motor in actuator component, has magnet carrier comprising two connectors such that connectors form positive connection and frictional connection to recess of ring magnet

摘要

The assembly has a permanent ring magnet (45) comprising a central, non-circular cylindrical recess. A magnet carrier (43) carries the ring magnet and comprises two connectors such that the connectors form a positive connection and a frictional connection to the recess of the ring magnet. The magnet carrier is made of plastic, where the connectors and a shaft (47) are formed on the magnet carrier. One of the connectors comprises bending elements i.e. deformable wings, that are turned away from an external peripheral part of the magnet carrier.
