Electromagnetic Force Modelling for Hybrid Magnetic Bearing
In this paper, a novel structure of hybrid magnetic bearing with PM bias and inductance displacement sensor is proposed. The operating principle of the hybrid magnetic bearing with PM bias is introduced. The Electromagnetic Force Model is built in the paper, which is useful for the hybrid magnetic bearing control. An example is given. The analysis of finite element method shows that the structure of the hybrid magnetic bearing with PM bias proposed in the paper is feasible and the calculation method for hybrid magnetic circuit is correct.
