に取り付けたことを特徴とするリニアモータ。 A yoke in which magnets arranged with alternately different magnetic poles are provided on one side in the longitudinal direction, and a plurality of coils whose winding directions are perpendicular to the magnetic flux direction of the magnets are mounted facing the magnets and attached to the yoke. In the linear motor, the plurality of coils are stacked at their ends, and the positions of the portions facing the magnets are different from each other in the direction of movement, so that none of the coils are aligned with the above-mentioned position. A linear motor characterized in that the linear motor is attached to the bobbin in a shape such that the distance from the magnet surface is uniform.
