FIELD: mechanical engineering. SUBSTANCE: line stepping motor has active armature 1 with toothed poles 2, excitation magnets 3 and phase windings 4 placed with gaps inside closed belt inductor 5 in which magnetically soft teeth 6 alternate with nonmagnetic intervals 7. Extended smooth magnetically soft yoke 8 which length is bigger than length of motor by value of required motor stroke is positioned on outside of inductor 5 opposite to working surface of armature without gap. Supports and guides to embrace armature with belt inductor provide for warranted working gaps and free motion of belt inductor about armature. Limitation of length of toothed zone of inductor makes it possible to manufacture it with high precision which increases accuracy of motion. EFFECT: increased accuracy of motion. 2 cl, 5 dwg
