Abstract

PURPOSE:To enable a linear motor itself to set the maximum position or quantity of movement of a movable element by providing a part of a stator base with a limiter for limiting the movement of said movable element. CONSTITUTION:A stator 1 is composed of a primary core 2, a drive winding 3, a permanent magnet 4 and a limiter 5. A movable element 6 has contact parts 6-a, 6-b and secondary core pole teeth 6-c provided on the surface opposed to primary core pole teeth 2-a. Said movable element 6 is step driven in the +Y or -Y direction by the interaction between a driving current made to flow through the drive winding 3 and the permanent magnet 4, primary core pole teeth 2-a and secondary core pole teeth 6-c. A movement in the +Y direction is controlled by the contact part 6-b and that in the -Y direction is limited by contact of the contact part 6-a with the limiter 5.
