Six Pole type Hybrid Magnetic Bearing for Turbo-Machinery
New six pole type hybrid magnetic bearing is introduced. It is intended to apply to high speed turbo-machinery. Traditionally turbo-machinery uses standard electro-magnet (EM) type active magnetic bearing (AMB) which requires PWM power amplifiers. Recently turbo manufacturer wants to develop their own magnetic bearing. Sometimes they are not accustomed with developing standard EM type magnetic bearings. The proposed magnetic bearing uses bias Permanent Magnet (PM), hence it is easily manufactured. The developed magnetic bearing also has good characteristics due to six directional control pole compared with the standard four directional control one.
