Abstract: The aim of the invention is to better compensate for specifiable forces on a magnetic mounting. This is achieved by a magnetic mounting device with a first magnet device (10), which is designed in an annular manner and which has a central axis, for retaining a shaft on the central axis in a rotatable manner by means of magnetic forces. The magnetic mounting device additionally has a second magnet device (12), which is independent of the first magnet device (10), for compensating for a specifiable force acting on the shaft. In this manner, the magnetic mounting device can compensate for the gravitational force or forces based on imbalances.

Abstract: A bias magnetic flux is formed so as to be passed through the electromagnet core of an electromagnet, and a bypass magnetic path, serving as a magnetic path for a control magnetic flux, is formed in parallel with a permanent magnet, the bypass magnetic path being magnetized in a direction in which passage of the bias magnetic flux is blocked, and thus, even if the permanent magnet and the electromagnet are disposed in locations where the mutual magnetic fluxes of the permanent magnet and the electromagnet are superimposed, the control magnetic flux formed by the electromagnet is passed through the bypass magnetic path, whereby loss of the control magnetic flux can be suppressed. Thereby, the permanent magnet and the electromagnet can be disposed in locations where the mutual magnetic fluxes are superimposed, whereby the device can be made smaller in size.

Abstract: An electromagnetic actuator generates electromagnetic forces across large radial gaps to support a body. The actuator has an actuator target having a rotational axis, and a target magnetic element arranged circumferentially around the rotational axis that has inner and outer magnetic poles. A cylindrical soft-magnetic target pole is magnetically coupled to the outer cylindrical magnetic pole of the target magnetic element. An actuator base includes radial poles arranged circumferentially around and radially spaced apart from the cylindrical soft-magnetic target pole. The radial poles and the cylindrical soft-magnetic target pole are magnetically coupled and define a plurality of magnetic control circuits. Control coils around the radial poles are configured to produce magnetic fluxes in the magnetic control circuits. The target magnetic element, the cylindrical soft-magnetic target pole, and the radial poles are magnetically coupled and define a magnetic bias circuit, the magnetic element producing magnetic flux in the magnetic bias circuit.

Abstract: A homopolar magnetic actuator is configured to exert controllable radial forces on a body adapted to rotate around an axis. The actuator comprises at least three radial magnetic pole assemblies distributed at some distances from each other along the axis, each including a plurality of poles adjacent to an actuator target on the body. Permanent magnets are used to induce bias magnetic fluxes in the assemblies with polarities alternating from assembly to assembly but remaining the same around the rotational axis. Having several small bias fluxes distributed between several pole assemblies instead of a large single bias flux facilitates designing an actuator with a high aspect ratio. A control coil around each pole can induce a control magnetic flux in the poles. These control fluxes affect magnetic flux distribution around the actuator target, resulting in magnetic forces exerted on the target.
