Abstract:

This paper investigated the calculation method of the static and dynamic characteristics of magnetic bearing.The general calculation method based on the basic solutions was put forward first.The basic solutions were defined based on local coordinate system, and then the coordinate transform relation between the static and dynamic characteristics of magnetic bearing with arbitrary structure and the basic solutions were deduced. Finally, the method of calculating the static and dynamic characteristics of magnetic bearing with arbitrary structure was provided. The calculation processes are quick, and a general and standardized method is also provided to calculate the static and dynamic characteristics of the magnetic bearing.

Key words: magnetic bearing, static and dynamic characteristics, basic solution, calculation method
