Sumitomo Drive Technologies HMS3105C Gear Motor

Sumitomo HMS3105C Gear Motor is a compact, 0.5 HP three-phase gear motor from Sumitomo Drive Technologies, pairing a 1730 rpm three-phase motor with a 59:1 reduction in an F-71M mounting. The 59:1 gear ratio increases output torque while reducing speed, yielding a theoretical output of approximately 29 rpm with the 1730 rpm input. The integrated motor-gearhead assembly provides a single package with a fixed flange and shaft arrangement in the F-71M configuration, facilitating mounting in systems designed for HMS-series motors. This unit is designed for industrial drive tasks where space is at a premium and a compact footprint is important, and it is powered from a standard three-phase supply. As part of Sumitomo's HMS lineup, the HMS3105C represents a specific combination of horsepower, gear ratio, and mounting that can simplify replacement or upgrades in equipment already using HMS components. The gear reduction allows higher torque at low speeds, which is advantageous for drives requiring controlled motion and reliable performance in automation environments.
