Magnetic bearing for active centering of a body mobile relative to another about at least one axis |
摘要 |
A magnetic bearing for active centering about at least one centering axis of a second body mobile relative to a first body has a first portion including two parallel ferromagnetic plates, a first core carrying a first coil and permanently magnetized means magnetized perpendicularly to the ferromagnetic plates, said first mounted between said ferromagnetic plates. The bearing has a second portion separated from the ferromagnetic plates of the first portion by a pair of airgaps of variable thickness parallel to the centering axis. The permanently magnetized means are offset relative to the core in a direction substantially parallel to the pair of airgaps and the ferromagnetic plates are provided with notches facing the permanently magnetized means and oriented transversely to the pair of airgaps.
