ABSTRACT:
A linear stepper motor comprising a stator bar having stator teeth and a slider having slider teeth. The slider is positioned under the stator bar. The surface of the stator bar opposed to the slider has a pair of flat portions with a predetermined width between the edges and the teeth. The flat portions serve as rail portions for the rollers mounted on the slider. On the surface of the stator bar extending between the pair of flat portions are formed a plurality of parallel grooves to provide a plurality of stator teeth. The surface of thes stator bar is hardened by plating with a metallic material.
