Yaskawa Sigma-7 gear motors
Rated from 50W to 15kW, Yaskawa Sigma-7 gear motors mesh with high-torque applications at low output speeds; 5 gear ratios are available, ranging from 3/1 to 50/1. The gearheads are matched with their companion servo motors in mounting conventions, coupling mechanics and output characteristics. The gear motors feature helical gearing, larger planet bearings and balanced concentric shaft couplings.
