First Claim
Patent Images
1. A rotary machine comprising a driven rotor and an electric motor that includes only a single stator and a driving rotor;
- wherein the stator is also executed as an electromagnetic bearing for the driving motor and includes a portion that effects magnetic suspension of the rotor and effects driving of the rotor;
wherein the driving rotor of the electric motor together with the driven rotor of the rotary machine forms a rotary unit.

Abstract
The rotary machine comprises a driven rotor and an electric motor having a stator and a driving rotor. The stator is also executed as an electromagnetic bearing for the driving rotor, and the driving rotor of the electric motor together with the driven rotor of the rotary machine forms a rotor unit, i.e. the two rotors form an integral rotor. The rotary machine can for example be a rotary pump, a centrifugal pump, a centrifuge or a stirring apparatus. The rotor can be constructed so as to be easily removable from the stator.
