| Abstract: | The relations between stiffness and damping performances and structure parameters of an active magnetic bearing (AMB) system and frequency specificity of the control loop are analysed herein. And also the effects of the differences in phase on stability, stiffness and damping properties of the system are presented. Meanwhile, a new concept of complex damping coefficient and the practical meanings as well as calculating methods for some properties in the system are derivated and discussed. |
