SIMOTICS S-1FG1 servo gear motors are compact gear motors. Compared to standard gear motors with asynchronous machines, they have smaller dimensions, less weight and a higher dynamic response. The type range includes helical, parallel shaft, bevel and helical worm gear motors in normal frame sizes and speed / torque classes. SIMOTICS S-1FG1 servo gear motors use the same actuation heads as SIMOGEAR gear motors. Flexible servo drive system for demanding applications. Siemens has expanded its drive portfolio for servo applications to include the SIMOTICS S-1FG1 servo gear motor, optimally matched with the SINAMICS S120 inverter system.


• Siemens is expanding its SIMOGEAR portfolio that meets market standards regarding mounting dimensions as well as customer requirements.

• Shorter and compact design with fine torque rating is standard for SIMOGEAR gearboxes.

• Combined with SIMOTICS reluctance motors and SINAMICS frequency converters, new drive systems emerge with excellent operation.


• Up to 200% overload capacity.

• Without permanent magnets, synchronous reluctance motor maintenance is easier than permanent magnet synchronous motors.

• SIMOGEAR reluctance gear motor contributes to the robustness of the entire system under different environmental conditions.

• Energy efficient

• Optimum functionality of the drive system is ensured by the interaction of the reluctance motor, gear unit and converter exactly matched to each other.

• The system has high dynamic performance through optimized control and low moment of inertia.

• SIMOGEAR reluctance geared motors energy efficiency exceeds IE4.
