| Abstract: | In this paper we reduced the magnetic force formulation of the active magnetic bearing (AMB), for the first time considering the effects of the corresponding part of the control electric flow with the displacement feedback. We aslo gave the requirement of the motion stability for the force. By solving the equation of the control flow we gained the formulations for evaluating and designing the AMB's stiffness, then discussed the effects of the AMB's characteristic parameters on the stiffness. |
