Stator core for a magnetic bearing and method of manufacturing the same

摘要

The tooth ends of the stator core (10) form N and S poles adjacent to each other in axial direction. The protrusion (11) extends from the N and S poles in circumferential direction, so as to be in close contact with each other. The core is formed of U-shaped laminated steel sheets interleaved with insulating material and has an opening at the center side, when viewed from the side of the shaft. An independent claim is included for method of manufacturing cores for magnetic bearing.
