Abstract
A miniature synchronous motor having a bell-shaped rotor and a damping body, freely mounted, but non-rotatable on the rotor shaft. The damping body being urged, at least substantially in a radial direction by a spring, the force of which also acts substantially equally for both bearings of the motor so as to reduce noise during operation.
Claims14
A miniature synchronous motor having a single damping body acting on the rotor, comprising a non-rotating damping body mounted for free rotation on the motor shaft, spring means acting on said body in one direction including a substantial radial component whereby said body is urged in an at least substantially radial direction against the shaft and radial play of the rotor is thereby prevented.
A miniature synchronous motor having a damping body acting on the rotor, comprising a non-rotating damping body mounted for free rotation on the rotor shaft, spring means acting onto said damping body in a direction comprising a radial and an axial component thereby urging said damping body and rotor respectively in a radial and an axial direction for preventing play of the rotor in radial and in axial directions.
