Servo geared motors

Why servo geared motors from Siemens?

Siemens’ servo geared motors are versatile and suitable for a wide range of applications. We offer both planetary gearboxes and standard gearboxes.

Coaxial and angled planetary geared motors:

Gearbox type NLC(W): Extremely rigid for high radial and axial loads with IP65 sealing.
Gearbox type NRK(W): Large output bearing and low internal friction for higher radial and axial forces.
Gearbox type NRB(W): Lightest gearbox with the highest power density and low friction bearing.

Servomotors with standard gearboxes:

Servo bevel geared motor: Transmission ratio range 3.5 to 244.3, torque range 15 to 8160 Nm
Servo parallel shaft geared motor: Transmission ratio range 3.6 to 413, torque range 17 to 5140 Nm
Servo helical geared motor: Transmission ratio range 3.4 to 373, torque range 14 to 5200 Nm
Servo worm geared motor: Transmission ratio range 6.2 to 102.5, torque range 46 to 1480 Nm

Key benefits

Install with flexibility

In addition to a premounted solution, you can also mount gearboxes to our servomotors and main motors through a KS adapter. Our motors equipped with standard gearboxes round out our portfolio.

Adapt to any application

Servomotors with planetary gearboxes are highly dynamic, compact and efficient, with optimum adjustment of the torque-speed ratio or the mass moment of inertia ratio between the motor and load.

Maximize efficiency

Servomotors with standard gearboxes have a compact, direct-mounting design, high efficiency and low torsional backlash, and low running noise due to helical teeth. They’re also maintenance-free and lubricated for life.

Featured capabilities

SIMOTICS S-1FK2 and S-1FT2

SIMOTICS S-1FK2 and S-1FT2 are fully tested and ready-to-run servo geared motors equipped with either a lightweight, low-inertia gearbox or inertia adjustment. Thermal dimensioning is simple with digital twin capabilities.

SIMOTICS S-1FK7 and S-1FT7

The ideal choice for motion control applications requiring very high accuracy and dynamic response. Three versions are available: with SP+ planetary gearboxes, NP planetary gearboxes or directly mounted planetary gearboxes.

SIMOTICS S-1FG1

These servo geared motors have compact dimensions, lower weight and higher dynamic performance. Variants include helical, parallel shaft, bevel and helical worm geared motors in the usual sizes and speed/torque graduations.
