Advances in the industrial field demand sophisticated electrical motors. However, degradation of traditional ball bearing systems can reduce the efficiency of the motor over time. In addition, bearings require regular maintenance such as lubrication and replacement. Moreover, they cannot be used under some specific environments such as high temperature and vacuum. In order to overcome these problems, this paper proposes a novel active magnetic bearing design. It has only four poles to control the horizontal and vertical suspension, and it is possible to increase the coil winding number without an increase in shaft length. Hence, we can design a high attractive force and stiffness bearing. The stator was initially designed by magnetic field analysis. A simple experimental setup was fabricated in order to confirm the operation principle and attractive force characteristic. The time domain dynamic performance was confirmed by simulation and experimental results. The experimental results verified that the proposed magnetic bearing has sufficient performance for industrial application. Additionally, a small size hydraulic generator was designed for future application.
