Title:
磁気軸受装置
Document Type and Number:
Japanese Patent JP4024382
Kind Code:
B2
Abstract:
A magnetic bearing apparatus is capable of supporting a rotatable rotor in a non-contact manner. The apparatus includes a plurality of electromagnets and a slit. The electromagnets are disposed around the rotor and support the rotor in a non-contact manner in an axial direction of the rotor and a radial direction thereof by a magnetic attraction force. At least one slit is formed in the rotor at a predetermined angle for making the conductivity discontinuous with respect to the rotational direction of the rotor. This construction makes it possible to cut an eddy current loss, which is induced when the rotor is rotated.
