    • In the linear motor 1, which is provided with a pipe shaped member 11, a stator 10 including the pipe shaped member 11 and a plurality of magnets 12, both being accommodated in the stator 10 in such a manner that the plurality of magnets 12 are aligned in a line in the pipe shaped member 11 and same magnetic poles of magnets, being adjacent to each other and included in the plurality of magnets 12, oppose to each other, and a moving part 20 movably disposed on a circumferential surface of the pipe shaped member 11 in an opposing state, the pipe shaped member 11 is provided with a stopper structure 30 disposed at an end portion of the pipe shaped member 11 so as to prevent the plurality of magnets 12 from dropping out of the pipe shaped member 11. Accordingly, it is possible to simply and securely fasten the plurality of magnets 12 into stator 10 without occurring dropouts of the plurality of magnets 12 from the pipe shaped member 11, and without generating any backlash between them.
    • 在设置有管状构件11的线性电动机1中,包括管状构件11的定子10和多个磁体12,两者都以多个磁体12的形式容纳在定子10中 在管状构件11的一行中排列成彼此相邻并且包括在多个磁体12中的磁体的相同的磁极彼此相对,并且可移动地设置在管的圆周表面上的移动部20 管状构件11在管状构件11的端部设置有阻止结构30,以防止多个磁体12从管状构件11脱落。 因此,可以将多个磁体12简单且牢固地固定到定子10中,而不会从管状构件11发生多个磁体12的脱落,并且在它们之间不产生任何间隙。

    • The method for manufacturing a linear motor includes the steps of: disposing the soft magnetic member around a peripheral space of a pipe shaped member, prior to the time when inserting a plurality of magnets into the pipe shaped member; aligning the plurality of magnets in a line in the pipe shaped member in such a direction that the same magnetic poles of the adjacent magnets oppose to each other; creating a stator by excluding the soft magnetic member after fixing the plurality of magnets by pushing them from an end portion of the pipe shaped member; and disposing a moving section on the outer circumferential surface of the stator in a movable state. According to the abovementioned method, it becomes possible to easily mount the plurality of magnets in a line in the pipe shaped member in such a direction that the same magnetic poles of the adjacent magnets oppose to each other, without employing any specific tool. Further, it also becomes possible to eliminate the conventional center axis, resulting in a reduction of a number of parts required and a cost reduction for assembling the structure concerned.
    • 线性电动机的制造方法包括以下步骤:在将多个磁体插入管状构件之前,将软磁体配置在管状构件的周围空间周围; 在管状构件的一行中沿着相邻磁体的相同磁极彼此相对的方向对准多个磁体; 通过从所述管状构件的端部推压所述多个磁体来固定所述软磁体,从而形成定子; 并且在可动状态下在所述定子的外周面上设置移动部。 根据上述方法,可以在不使用任何具体工具的情况下,以相同磁体的相同磁极彼此相对的方向将多个磁体容易地安装在管状部件中的一行中。 此外,也可以消除常规的中心轴线,从而减少了所需的部件数量以及用于组装相关结构的成本降低。
