Bearingless Axial-Force/Torque Motor with Reduced Number of Power Switches

Activity: Talk or presentation › Contributed talk › science-to-science

Description

Earnshaw’s theorem forbids mere passive stabilization of a stationary rigid body with magnetostatics fields [1]. Hence, at least one degree of freedom has to be controlled by other means. Often, active electromagnetic suspension is implemented for stabilizing these remaining unstable degrees of freedom. Very economic magnetically levitated drive systems become feasible, when active axial-force generation is combined into a motor, while the remaining radial degrees of freedom are stabilized by two radial permanent magnetic ring bearings.
