摘要

Active magnetic bearing (AMB) has drawn such a significant amount of consideration in the rotating machinery industry because of its advantages against conventional bearing such as rolling cement bearing, fluid film, etc. AMBs introduce subsidiary features to the high-speed system, such as remove friction loss, reduce maintenance. This manuscript describes a novel, simplified, and economical design, analysis, and hardware implementation of single-coil Ⅰ-type active magnetic bearing for high-speed application. Two types of controllers have been for the proposed system for the 10 mm air gap, one for sensing the position and another for sensing the current. A 3D finite element model of the AMB system is built. Then the magnetic analysis is performed under different conditions and the attractive force characteristics for this proposed system have been analyzed by the 3D finite element method. In the test setup speed of AMB is compared with conventional bearing. From the test result, it is observed that the designed magnetic bearing meets the high-speed application criteria.
