Title:
MAGNETIC SUSPENSION DEVICE
Document Type and Number:
Japanese Patent JP3057047
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a suspension device to remove an unnecessary loss incurring due to an induced eddy current.
SOLUTION: A magnetic suspension device is provided with a rotor 10 to effect relative rotational movement along a given rotation symmetrical passage to a stator 14. The rotor 10 consists of a rotary body 11 fundamentally formed of a conductive non-magnetic material. At least one magnetic means 12 is fitted in the stator 14, and consists of at least one rotation symmetrical magnet 12 coaxial with a rotary shaft. A magnetic means is arranged to generate a rotation symmetrical magnetic field coaxial to the rotary shaft. Only when the rotary body 11 has a tendency to be deviated from a given passage and eccentrically rotated, a magnetic field generates an eddy current induced in the rotary body 11 and the eddy current generates a restoration stable force.
