Abstract

A rotor arrangement having radial bearings includes a stator (2), a rotor (1) rotatably mounted in the stator, and two axially separated magnetic radial bearings (3) which function to support the rotor (1) radially from the stator (2) for rotation in a contactless fashion. The rotor is supported axially by a mechanical support (4) at least at one end of the rotor.
