“…To provide a control of the rotating machine in the axial direction, the Axial Active Magnetic Bearings (AAMBs) are being widely used in space systems, physics, robotics and industrial applications [11]. The design of the Active Magnetic Bearings (AMBs) is in a constant evaluation, starting with a structure using permanent magnets [1,3,6,9,17], a typical active configuration, which contains two ring solenoid magnets [2,18,19], by inserting permanent magnets in the magnetic circuit [19,20,21], the use of separate pole pieces [8], up to a hybrid design, in which the function of an axial and radial bearing is combined [4,7,12,22,23].…”

The paper presents a numerical model of the novel design of the axial magnetic bearing with six cylindrical poles. The motivation behind this idea was to eliminate vibrations in rotating machinery due to the axial load. Common conception of such a bearing provides a single component of the electromagnetic force, which is not enough to reduce transverse and lateral vibrations of the armature. The proposed design allows for avoiding wobbling of the disc with the use of a few axial force components that are able to actively compensate the axial load and stabilise the disc in a balanced position. Before a real device is manufactured, a virtual prototype should be prepared. The accurate numerical model will provide essential knowledge about the performance of the axial magnetic bearing.
