Research on Dynamics Performance of Permanent Magnet Suspension System with Variable Magnetic Circuit
摘要
Abstract
This paper proposed a magnet suspension system with variable magnetic circuit ,which was composed of a servo motor ,a radial magnetized disk permanent magnets and a pair of magneti-zers .The suspension force was provided by the permanent magnet in the system ,the servo motor drove the disk permanent magnet rotation ,changed the magnetic flux flowing through the suspended object ,then realized the real time control of suspension force .The suspension system could realize zero attractive force for avoiding the disadvantages of touching attraction ;could achieve zero-power suspen-sion in the stable suspension state for save-energy suspension ;could change the magnetic poles for re-alizing multi-degree suspension system ,the system’s magnetic flux leakage features were considered , the system’s parameterized model was set up ,the dynamics and control characteristics of this system were analyzed .Finally ,the suspension characteristics were analyzed using numerical simulation ,and the results show that the system can realize stable suspension under certain disturbances ,and possess ideal time-domain and frequency-domain response characteristics .关键词
