A motor having a magnetic fluid bearing structure, which includes at least one bearing, at least one magnetic element and a magnetic fluid. The bearing is telescoped onto a shaft, and the magnetic element is coupled to the bearing. The magnetic fluid is kept between the bearing and the shaft. According to a magnetic effect between the magnetic fluid and the magnetic element, it is possible to prevent a lubricant of the bearing from leaking, and a hydraulic pressure of the magnetic fluid provides additional axial and radial supports to make the shaft rotate steadily relative to the bearing. |
