摘要： A radial magnetic bearing having an inner rotor including a central shaft having a ferromagnetic armature mounted on the shaft and an outer stator providing a plurality of electromagnets including poles made of ferromagnetic material which project radially inwardly towards the rotor is provided. As such, air-gaps (e) are left between end faces of the poles and the ferromagnetic armature, and coils wound around the poles. The poles are extended through outer portions attached to a supporting member. Each pole and the corresponding outer portion are included in an angularly segmented module providing a stack of laminations made of ferromagnetic material. The outer portion defines shoulders with respect to the corresponding pole, the outer portion contacting outer portions of neighboring segmented modules and the outer portions of all segmented modules being assembled by clamping rings, wherein the coils located in free spaces around the poles are mounted in a string.

摘要： A magnetic bearing assembly includes a lamination stack with coil apertures extending between opposing sides. A continuous unitary insulation layer is overmolded onto the opposing sides and within the coil apertures providing a coil aperture lining. The insulation layer includes a wall within the coil aperture adjoining coil aperture lining and bisecting the coil aperture into first and second openings. A coil portion is disposed in each of the first and second openings and electrically isolated from one another by the wall. The magnetic bearing assembly is arranged in a refrigerant compressor that includes an electric motor rotationally configured to rotationally drive an impeller via a shaft. A controller is in communication with the magnetic bearing and configured to energize the coils and provide a magnetic field rotationally supporting the shaft.

摘要： A magnetic radial bearing with low eddy current losses is made compact and easily actuable. For this purpose, a radial bearing with four coils (S1, S2, S3, S4) is proposed, said coils lying opposite one another in pairs on two axes (X, Y). The coils are controlled by a three-phase current (U, V and W). The amplitudes of the currents of the phases (U, V and W) are each evaluated using a sine function which is phase-shifted with respect to one another through 120 DEG. The control is performed by a control device at a variable operating point, which fixes the value for the evaluation of the amplitudes for the individual phases corresponding to the respective sine function.

摘要： Provided is a magnetic bearing device capable of facilitating manufacture of the magnetic bearing device and improving precision in production thereof while maintaining eddy current reducing effects. The magnetic bearing device 10 supporting a rotating shaft 3 with a magnetic force includes a plurality of magnetic poles 5 arranged in the circumferential direction of the rotating shaft 3. Each magnetic pole 5 includes an inner end surface 5b facing the outer surface of the rotating shaft in proximity thereto. The magnetic poles which are adjacent to each other in the circumferential direction respectively extend in the axial directions of the magnetic poles 5 to the inner end surfaces 5b of the magnetic poles so as to virtually interfere with each other in the vicinity of the outer surface of the rotating shaft. The virtual interfering portions 5a of both the magnetic poles 5 capable of interfering with each other are removed by cutting.
