MAGNETIC BEARING WITH FORCE COMPENSATION Russian patent published in 2017 - IPC F16C32/04 F16C39/06 H02K7/09 

FIELD: physics.

SUBSTANCE: invention relates to a magnetic bearing design. The magnetic bearing design consists of the first magnetic device, which has annular shape and central axis (1) for holding a shaft (2), also capable to rotate around the central axis by means of magnetic forces, the second magnetic device, which is independent from the first magnetic device in order to compensate the predetermined force, which acts on the shaft (2), wherein the second magnetic device has annular shape and located concentrically with the first magnetic device. The first magnetic device has the first system (10) of the coils and the second magnetic device, having the second coils system (12), each coils system has respectively a plurality of poles pairs, and the number of pole pairs of the second coils system (12) is exactly one less, than the number of poles pairs of the first coils system (10). The first magnetic device serves for the shaft (2) centering and the second magnetic device counteracts to the force of gravity. In this way the forces of gravity or the forces caused by the overbalance can be compensated.

EFFECT: invention provides the creation of the improved method for installation the rotating shaft in the magnetic bearings, with the help of which the predetermined forces, acting on the shaft, can be compensated.
