Abstract
In order to improve the smoothness of operation of a shaftless spinning rotor embodied as the rotor of an axial field motor wherein the rotor is supported by a magnetic gas bearing, a guide magnet arrangement for generating a magnetic guiding field is decoupled mechanically from the drive component of the stator. To that end, separate magnet and stator components are connected to one another by means having both elastic and damping properties, e.g., rubber. This mechanical decoupling makes it possible for the separate components to execute vibration independently of one another and for vibration to be transmitted from one component to another only in highly attenuated form. Hence, machine vibration can substantially be prevented from affecting the smoothness of rotor operation. Tangential forces generated by harmonics and radial forces caused by magnetic or mechanical asymmetries can likewise be absorbed by the stator, with an attendant improvement in smoothness of rotor operation.
