| description | New six pole type hybrid magnetic bearing is introduced. It is intended to apply to high speed turbo-machinery. Traditionally turbo-machinery uses standard electromagnet (EM) type active magnetic bearing (AMB) which requires PWM power amplifiers. Recently turbo manufacturers want to develop their own magnetic bearing. Sometimes they are not accustomed to developed 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. An experimental setup is fabricated and tested with good results. Finally auto balancing control is applied to the free side of proposed magnetic bearing. |
