Research on Heat Dissipation Scheme of Active Magnetic Bearing Based on ANSYS

Compared to mechanical bearings, active magnetic bearings eliminate friction, resulting in lower energy losses. However, due the magnetization characteristics and high-frequency working of core material bearing, there will be high wind friction loss, eddy current hysteresis loss copper bearing. These losses generate heat increase internal temperature which not only affect control accuracy bearing stability rotor suspension, but may also cause irreversible damage components inside In this paper, different dissipation schemes are established discuss influence suspension on generation
