摘要： An electromagnetic actuator can exert a radial electromagnetic force on a body that is configured to rotate about a rotational axis. The actuator includes a radial control magnetic pole assembly that includes radial control poles adjacent to and spaced apart by air gaps from the body. The actuator includes a permanent magnet (PM) magnetized along the axis, having one pole in contact with an axial face of the assembly and located proximate to a lateral surface of the body. The PM is magnetically coupled to the body in a non-contact manner resulting in a bias magnetic flux in the air gaps. The actuator includes a control coil around the radial control poles located radially outwards from the PM. Electrical current in the coils generates control magnetic flux in air gaps. The non-uniform net magnetic flux distribution around the body results in a radial electromagnetic force exerted on the body.

摘要： A rotating mass energy store includes a rotor that contains conductors and a magnet arrangement. The rotating mass is symmetrical about axis of rotation and is hollow with a cavity, wherein an electrical stator is located in the cavity. All components of the energy store are enclosed in a housing that has a fitting/connection for a vacuum pump and or seal, and wire connection seals for conductive wire to pass through. The rotor is permanently magnetically levitated axially and radially. Electrical energy is exchanged and stored as kinetic energy in a rotating mass, otherwise known as a rotor.

摘要： Radial, soft magnetic rotor disk elements which engage in each other and soft magnetic stator disk elements form a magnetic bearing device. The elements are provided with teeth-like extensions which are arranged opposite to each other over an air gap on sides which are oriented towards each other. Magnetic fields, which may be produced by permanent magnets or electromagnets, are assigned to the stator disk elements to produce a magnetic maintaining flow which is oriented in an axial direction between the disk elements for radial adjustment. An electromagnetic winding is also provided in the region of the central plane of the bearing device for axial adjustment, which enables a magnetic control flow, which superimposes the magnetic maintaining flow, to be produced.
