摘要:
A mover includes a permanent magnet array having a plurality of permanent magnets that are magnetized in a direction perpendicular to a motion direction of the mover such that magnetic poles having different polarities alternately appear on magnetic pole surfaces of the plurality of permanent magnets in the motion direction. A stator includes first and second magnetic pole portion arrays and three excitation windings. Each of the magnetic pole portion arrays include a plurality of plate-like magnetic pole portions disposed on both sides of the permanent magnet array in the perpendicular direction. Each of the excitation windings is hollow-structured whereby two magnetic pole portions included in the first magnetic pole portion array and two magnetic pole portions included in the second magnetic pole portion array are located in an internal space of the coil and are excited by the corresponding one of the excitation windings.
