Abstract
A planar motor system comprises a platen with a first planar motor component and a stage with a second planar motor component. The stage can move along a first cardinal axis or a second cardinal axis. The planar motor system further comprises a drive system. When the drive system is energized in a first drive configuration, it applies a first force and a second force. The first force and the second force are not parallel to any cardinal axis. A vector sum of the first force and the second force is parallel to the first cardinal axis. When the drive system is energized in a second drive configuration, it applies a third force and a fourth force. The third force and the fourth force are not parallel to any cardinal axis. A vector sum of the third force and the fourth force is parallel to the second cardinal axis.
