Servo geared motors – open for gear variety

SIMOTICS S-1FG1 servo geared motors

The SIMOTICS S-1FG1 servo geared motors are compact geared motors. Compared to standard geared motors with induction machines, they have smaller dimensions, weigh less and have a higher dynamic response. The range of types covers helical, parallel shaft, bevel and helical worm geared motors in the usual frame sizes and speed/torque classes. The SIMOTICS S-1FG1 servo geared motors use the same operating heads as the SIMOGEAR geared motors. Flexible servo drive system for demanding applications. Siemens has expanded its drive portfolio for servo applications to include the SIMOTICS S-1FG1 servo geared motor that is optimally harmonized with the SINAMICS S120 inverter system.
