摘要：
In this paper, new strategies of vibration suppression in flexible shaft of a motor with active and passive magnetic forces are presented. The shaft magnetic damping is originated from the principle of a bearingless motor having a radial magnetic force generation. The radial force is used for shaft vibration suppression in order to go through the first critical speed. Simplifications are described in suppression force system. Elimination of power source with self-excitation is proposed. Further elimination of sensors, controllers, and inverters is also proposed, although the effectiveness is limited.
