Title: Magnetic bearing device
Inventor: YADA YUJI
IPC: F16C32/04
Filed: 2001-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic bearing device provided with a positional detection sensor capable of obtaining a sufficient sensibility even in sensing set apart from a can and being kept insusceptible to the adjacent electromagnet.
