Abstract
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.
