Recently, advances in office and factory automation equipment have led to the development and commercialization of direct drive systems using linear motors. In fact, it has also been reported that X-Y plotters have been marketed as plotters that use two linear motors (one for the X direction and another for the Y direction) and air bearings. However, the authors have yet to withness the practical development of a direct-drive Surface Motor ("SFM") that can operate in these two directions under direct drive and using only one motor.In view of this situation, the authors proposed an SFM that enables bidirectional motion and reported upon its basic structure and specifications.The SFM's stator is a checkerboard arrangement of N-pole and S-pole magnets, laid atop a back iron plate. The mover is a bakelite truck platform that includes core coils. The SFM and the PM-type linear pulse motor both use the same operation principle.In this paper, the authors will show the mathematical development that supports its bidirectional control system, and report on the results of prototype drive tests.The authors have developed a drive system that enables excitation. The excitation sequence is generated by a computer. The authors conducted drive tests based on the drive principles described above.
