Method for coating and/or varnishing of the magnet rings of a rotor magnet bearing, rotor magnet bearing and vacuum pump

摘要

The method involves arranging magnetic rings (4) of the magnetic bearing on a rotor (1) on an intended location (3), so that exposed surfaces (10) of the magnetic rings are coated under vacuum and painted with UV curable paint. A spray device (11) is moved within the rotor during the spraying process of the magnetic rings. Rotation devices (5, 6) are arranged to drive the rotor in rotation. A coating substance and paint are placed in a limited space of the rotor magnetic rings. An independent claim is also included for a rotor.
