Abstract:
A two-axis motion system that comprises:first and second electromagnetic stators, each having associated electrical windings, means for mounting said stators in stationary position relative to each other with said first stator being disposed in a first plane, and means for making stationary electrical connection to said windings of both said stators, first and second electromagnetic armatures, means mounting said first armature for linear motion along a first axis in a second plane overlying and adjacent to said first stator such that electromagnetic coupling between said first stator and said first armature propels said first armature along said first axis, and means mounting said second armature to said first armature for linear motion along a second axis in said second plane overlying and adjacent to said second stator such that electromagnetic coupling between said second stator and said second armature propels said second armature along said second axis with respect to said first armature.
