Besides the advantages of the normal magnetic bearing, three-pole magnetic bearing has some characters of small volume, low power loss and low cost. So the three-pole magnetic bearing has a wide application prospect in vacuum space, spotless area, high speed and many other fields. The principle and structure of the three-pole magnetic bearing are first described. Then, the works made by native and abroad researchers about three-pole active magnetic bearing and the three-pole hybrid magnetic bearing are introduced. And the research statues of the key technologies of the three-pole magnetic bearing are summarized. Finally, the trends of the three-pole magnetic bearing are analyzed based on the magnetic bearing developing directions of high speed, high precision and low cost.
