Title:
能動型磁気軸受
Document Type and Number:
Japanese Patent JP4184950
Kind Code:
B2
Abstract:
The active magnetic bearing (1) comprises a stator (2) fitted with electromagnet windings (21) and a first stack of ferromagnetic laminations (22), a rotor (3) fitted with a second stack of ferromagnetic laminations (9), servo-control circuits (10), and position detectors (4, 5, 6). The first stack of ferromagnetic laminations (22) comprises in succession in the axial direction: at least a first sub-set (2a) of laminations (22a) presenting first notches housing electromagnet windings (21); a second sub-set (2b) of laminations (22b) presenting both first notches housing electromagnet windings (21) and second notches housing a radial detector (6); and a third sub-set (2a) of laminations (22a) presenting first notches housing electromagnet windings (21). The first stack of ferromagnetic laminations (22) further comprises fourth and fifth sub-sets (2c) of laminations (22c) at its ends, presenting the same notches as each other and housing respective first and second axial detectors (4, 5).
