Document Type and Number:
Japanese Patent JP2004340361
Kind Code:
A
Abstract:
To elongate the life of a product by generating repulsive force between a stator magnetic unit and a spindle magnetic unit for isolating a spindle a specified distance from a stator to prevent vibration and noise due to inclination.
The magnetic suspension bearing located between the spindle and the stator of a rotational device comprises the stator magnetic units mounted on the upper and lower parts of the stator and the spindle magnetic units which are mounted on two ends of the spindle.
