Title:
ELECTROMAGNETIC SUSPENSION BEARING
Document Type and Number:
WIPO Patent Application WO/2007/048273
Kind Code:
A1
Abstract:
The present invention discloses an electromagnetic suspension bearing, which
comprising a stator, a rotor, an outer casing, an inner casing and a current controlling
device. The rotor and the stator are assembled together, with the rotor being
disposed inside the stator. The pentagon electromagnets of the stator and those
of the rotor are arranged in an alternate manner so that the rotor may be fixedly
held in the stator through the magnetic repulsion therebetween. With this structure,
it can obtain stable bearing. Also, the outer casing and the inner casing enclose
the rotor and the stator so as to shield the electromagnetic force generated by
the electromagnet. In addition, the current controlling device is used to control
the amount and the direction of the current, and thus control the strength of the
electromagnetic force and the polarity.
