  • Patent number: 6921997
    Abstract: The present invention provides an active magnetic bearing (AMB) with improved configuration. The active magnetic bearing includes a stator which possesses only three magnetic poles. The three magnetic poles are arranged radially with an equiangular degree along an internal circumference of the stator and not in the same semicircle. Each of the magnetic poles is equipped with an individual power amplifier for providing coil current. In the other way, two of the magnetic poles can be equipped with only one power amplifier, and the other magnetic pole is equipped with an individual power amplifier so as to reduce the number of the power amplifiers.
