ABSTRACT:
A stepper drive system including a pair of linear belt flights trained between interior surfaces of a fixed frame and a reciprocable armature carriage with the belts alternately clamped to the carriage so as to successively advance the belt flights in opposite directions. The armature carriage is powered by a linear motor defined by a pair of permanent magnets fixed to the carriage and at least one, preferably two, electrically conductive coils fixed in the frame such that when energized the armature carriage will be driven in one of two directions along a given path between fixed stops established by the frame. To clamp the belt flights to the carriage, an energizeable belt gripping device is mounted on the carriage and includes a reciprocable armature fitted with belt deforming nipples, aperture engaging pins, or a planar surface for friction engagement. Alternately, the belt flights may be also coated with a magnetically permeable material so as to be electromagnetically drawn against the belt clamp.
