STATOR CORE FOR A MAGNETIC BEARING AND THE METHOD OF MANUFACTURING IT |
摘要 |
Stator cores for a homo-polar magnetic bearing, wherein toothed ends of stator cores around a rotor form N poles and S poles adjacent in the axial direction, and the method of manufacturing them. The stator core 10 is provided with protrusions 11 of adjacent N and S poles extended circumferentially so as to be in contact with or in close proximity to each other, and is composed of U-shaped laminated steel sheets interleaved with an insulating material, of which the center side is open when viewed from the centerline side. In addition, the core is composed of a first yoke, a second yoke and a stem unit that is a magnetic body placed and fixed between the yokes, and at least the stem unit is composed of a magnetic material powder, solidified in resin.
