S Series Helical Worm Gearmotors are helical and helical-worm combinations, so they are more efficient than normal helical-worm gear units. Torque: 73-10200N.m. Ratio: 23.8-389. Power: 0.12-45KW. Due to their outstanding efficiency, these drives can be used in every industrial sector and tailored to individual torque and speed requirements. The reduction ratios afforded by the helical-worm gear stage and the low noise levels during operation make these gearmotors ideal low-cost solutions for simple applications.
