| 摘要 |
The invention relates to a magnetic circuit structure in an apparatus in which the first machine means is a stator (1) with a winding (3) and the second machine means is a rotor (2). The magnetic circuit is arranged to generate a force effective between the stator (1) and the rotor (2) in the axial direction of the rotor (2), particularly to provide axial magnetic bearing. The separation between the parts of the magnetic circuit effective in the stator (1) on one hand and in the rotor (2) on the other hand is arranged in that part of the magnetic circuit in which the direction of the magnetic flux deviates from the axial direction of the rotor (2), and that the different parts of the magnetic circuit are partly adjacent to each other in the axial direction of the rotor (2), to direct the magnetic flux effective in the magnetic circuit at least partly in the axial direction of the rotor (2). |
