摘要： A bearing and drive system (1) comprising at least one electric engine (2) together with a control (50), wherein the bearing force of the respective bearing degree of freedom of the engine (2) can be actively influenced, also comprising an actively influenceable bearing (6, 7), which operates in a contact-free manner, together with a control (55). The control (56) of the engine (2) has two operating modes, of which one operating mode minimizes the effects of force of the electric engine (2) on the bearing degrees of freedom concerned, and the other operating mode actively generates a bearing force of the electric engine (2) in order to support the bearing. A detection and switching unit (52', 52'') for switching between the two operating modes when at least one operating parameter exceeds or drops below a predetermined limit value is provided, and a regulating or control unit (35) for the engine (2') and the bearing (6, 7) is connected to said detection and switching unit.

摘要： A fluid energy machine is provided. The fluid energy machine includes a housing having a motor, an impeller, at least two radial bearings, and a shaft which extends along a shaft longitudinal axis and which supports the impeller and a rotor of the motor wherein the shaft is mounted in the radial bearings. The motor includes a stator which at least partially surrounds the rotor in the region of the motor. A gap which extends in the circumferential direction along the shaft longitudinal axis is formed between the rotor and stator and between the rotor and the radial bearings, which gap is at least partially filled with fluid. The motor is embodied as a bearing and is connected to a controller which activates the motor so that forces acting radially with respect to a shaft longitudinal axis can be exerted in addition to torques for driving the fluid energy machine.

摘要： The invention concerns a rotary pump (3) having a housing (9) and a rotor (2) with blades (1b) which is placed inside the casing. The rotor (2) comprises a passive magnetically active rotor part (1) and the housing (9) is surrounded by a stator (7) having electrical windings (8a, 8b, 8c, 8d, 8e, 8f, 8g, 8h) and teeth (7a, 7b, 7c, 7d, 7e, 7f, 7g, 7h). The stator (7) and the rotor part (1) form a motor that has no bearings, whereby the rotor part (1) can be actively controlled and operated by means of the electrical windings (8a, 8b, 8c, 8d, 8e, 8f, 8g, 8h) through three degrees of freedom. The rotor part (1) and the teeth (7a, 7b, 7c, 7d, 7e, 7f, 7g, 7h) of the stator (7) are designed geometrically in a mutually adapted manner and are placed in such a way that the rotor part (1) is retained in the stator (7) through three additional degrees of freedom not actively controlled through passively operating reluctance forces, in order to mount the rotor (2) inside the housing (9) so that it can be driven and float frictionlessly.

摘要： This invention is a rotating electrical machine comprising two major components capable of relative rotation about a common axis and separated by an air gap in which magnetic fields linking the two main components through the air gap act both to exert torque and lateral forces. A set of windings is present on at least one of these components and this set of winding is used to generate a distribution of flux having two parts: the first part serving primarily to case torque and the second part serving to cause a net lateral force between the two main components. This machine uses the physical connection of the coils within the phases of the machine such that separate sources can be used for supplying currents for generating torque and lateral forces independently. The voltage and current ratings of the supply used for generating the lateral forces can both be substantially lower than the corresponding ratings of the supply used for generating the torque.
