Commutation of a Magnetically Levitated Planar Actuator with Moving-Magnets

IEEJ Transactions on Industry Applications, 2008
This paper describes a novel commutation strategy for planar actuators with moving magnets and integrated magnetic bearing. The algorithm decouples the force and torque components directly and determines the current set-points of the coils by minimizing the ohmic losses.
