摘要： A linear actuator displaces a relative position between a guide rail and a slide table, which is arranged in confronting relation to the guide rail. Projections are formed on opposite end sides of the guide rail, the projections extending along a direction of displacement and projecting toward the slide table. The slide table is disposed between the projections on the opposite end sides of the guide rail, with rigid balls being interposed therebetween. Guide grooves and guide grooves, which rollably support the balls, are provided on the projections on the opposite end sides of the guide rail and on the slide table. The guide grooves and the guide grooves apply, on the balls, a pressure caused by a magnetic attractive force of permanent magnets.

摘要： The electromagnetic actuator is a linear electromagnetic actuator in which the relative position between a slide table that supports permanent magnets thereon and a guide rail that supports a coil, which is arranged in confronting relation to the permanent magnets, is displaced by means of a thrust force generated by a current flowing through the coil. The coil is disposed on the guide rail through a low coercive force magnetizable material body, the coercive force of which is lower than a predetermined value. Consequently, generation of residual magnetization can be suppressed, and an influence on the thrust force caused by such residual magnetization can also be suppressed.
摘要翻译：电磁致动器是线性电磁致动器，其中支撑永磁体的滑动台和支撑与永磁体相对的线圈的导轨之间的相对位置通过推力由流过线圈的电流产生。线圈通过低矫顽力可磁化材料体设置在导轨上，该矫顽力可磁化材料体的矫顽力低于预定值。因此，可以抑制剩余磁化的产生，并且还可以抑制由这种剩余磁化引起的推力的影响。
