| Abstract: | A new structure of radial permanent magnet biased hybrid magnetic bearing(HMB) with two degrees of freedom was designed.Structure characters and working principle of HMB were introduced.Magnetic field modality was analyzed and come to ideal conclusion.Parametric programming was simply introduced.Then the whole system of HMB was established.Static experiment about this HMB was done.Finally,come to conclusion that this HMB was lower power consumption. |
