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： An object of the present invention is to provide a bearingless rotary machine which is capable of stably controlling the levitated position of a rotor of an induction motor even if the rotor comprises a squirrel-cage type rotor that is simple in structure and can easily be manufactured.
A bearingless rotary machine has a rotor having secondary current paths and a stator spaced from the rotor by a gap. The stator has two kinds of windings for imparting a rotating and a levitating and supporting force to the rotor. The rotary machine has a magnetic field command calculator, magnetic flux distribution detecting means and correcting means for adjusting the detected control magnetic flux distribution to coincide with the magnetic field distribution command.

摘要： There is provided an electric machine comprising a stator, a rotor configured to rotate relative to the stator, the stator having a phase arrangement. The phase arrangement includes a number of legs connected in parallel at a first primary junction and a second primary junction. The number of legs is an integer greater than two. Each leg includes a plurality of coils connected in series through a respective intermediate junction, with each coil comprising a number of turns. Each leg is connected to at least one other leg of the legs by a branch at the respective intermediate junctions such that the phase arrangement is in the form a bridge circuit. The phase arrangement is configured to conduct, through each leg, a motor current through the respective in series coils between the first primary junction and the second primary junction. The phase arrangement is configured to permit an alignment current to flow between the first primary junction and the second primary junction along an alignment current path which passes through at least one coil of two different legs of the number of legs via a respective branch. The electric machine is configured so that the motor currents cause a torque to be applied to the rotor for rotation relative to the stator, and the alignment current causes a translational force to be applied to the rotor.

摘要： A magnetically-levitated centrifugal pump, in which permanent magnets are not used for disposable sections, is provided with a pump head section and a pump section. The pump section comprises a stator, a torque transmission disc, a motor, a displacement sensor, and a pump housing. The stator has longer depth than protrusion length of a rotor accommodation section in which permanent magnets are not used, is equipped with a rotor insertion section, in which the rotor accommodation section is disposed so as to be able to be inserted and removed, on the side of one end section, and disposes three or more than three electromagnets for magnetic bearings, which magnetically couple with the rotor, at equal intervals. The torque transmission disc, which is disposed inside the rotor insertion section and which magnetically couples with the rotor, is formed by bonding ring components, which are made from magnetic material and are provided with protrusions at positions opposite protrusions on the rotor, between plural ring-shaped permanent magnets, which are magnetized in the thickness direction thereof, such that like-poles face each other, and then by placing another ring component on top of the uppermost ring-shaped permanent magnet. The motor rotationally drives the torque transmission disc. The displacement sensor measures radial displacement of the rotor.
