This paper concerns the design, optimization, and commutation of a six-degree-of-freedom planar actuator with an active magnetic bearing. The planar motor has a stationary coil array and a translator with a Halbach magnet array. During movements in the xy plane, the set of energized coils changes with the position of the translator. In this paper, a method for the electromagnetic design of this type of actuator is discussed, and several topologies are compared. The best performing topology in
