Claim 16:
17. The linear electrical machine of claim 1, wherein the controller controls the propulsion forces, generated by the array of electromagnets, across the reaction platen so as to:
impart a controlled yaw moment on the reaction platen, yawing the reaction platen about a yaw axis, substantially normal to the drive plane, from a first predetermined orientation relative to the frame, to a second different predetermined orientation relative to the frame; or
impart a moment couple on the reaction platen effecting controlled yaw of the reaction platen so as to effect at least one of positioning and centering of a wafer payload on the reaction platen relative to a predetermined wafer holding location of the frame.
