The S series helical worm gear motor combines a high-efficiency helical input stage with a worm gear output stage in one compact right-angle drive — the practical choice for small conveyors, wastewater treatment equipment, food and packaging machines, wood processing and similar duty where a right-angle output is needed but a full worm unit would waste energy.
Because the first stage is helical rather than worm, overall efficiency stays well above that of a comparable single-stage worm drive, and the unit runs noticeably cooler on continuous duty. The worm output stage delivers smooth, quiet operation and high ratios in a short axial footprint, with output torque from 92 to 3,600 N·m across the range.
Ratios from 5.36:1 to 19,738:1 cover slow-running applications directly — large ratios are achieved by combining stages, so most duty points are met from a standard frame without custom gearing. Frame sizes run from S37 to S97 with motor power from 0.12 to 22 kW.
Every unit is supplied as a complete motor-gearbox assembly matched to the duty point: motor power, pole number, ratio and mounting position are checked against your application data before the order is released, and each unit is run-tested before packing. Foot-mounted (B3), flange-mounted (B5 / B14) and shaft-mounted (SAF / SAZ) versions are available.
