Sigma-7 Gearmotor Continuous Torque Ratings

This document provides experimentally determined continuous output torque ratings for Sigma-7 gearmotor combinations (S7A, S7J, S7G, S7P) based on dynamometer testing, showing how mounting a servomotor to a gearhead affects heat transfer and torque capacity. It includes tables of continuous torque percentages for specific gearmotor model numbers and offers recommendations for mitigating high operating temperatures, such as reducing load, adjusting motion profiles, or using forced-air cooling.
