Based on the presented configuration design, the simplified torque calculation model and non-linear system dynamic model have been proposed, and air bearing combined with magnetic levitation mechanism is developed for alleviating the friction and resistance to improve the dynamic performance of this M-DOF actuator. The fluid field model is built in computational fluid dynamics software. Different structure parameters and conditions are computed and compared with the vortex torque characteristics and pressure distribution. A linear mathematical model of the magnetic levitation force is deduced and corresponding control scheme with power drive unit is discussed. Experiment results show that the actuator can effectively implement 3-DOF motion combined with the combined levitation modes, and that the proposed approach can be applied to m-DOF actuators of the same kind effectively.<p>DOI: <a href="http://dx.doi.org/10.5755/j01.eee.19.3.1387">http://dx.doi.org/10.5755/j01.eee.19.3.1387</a></p>}, number={3}, journal={Elektronika ir Elektrotechnika}, author={LI, Zheng}, year={2013}, month={Feb.}, pages={27-32} }
