Step 1: The ideal servomotor

SIMOTICS S‑1FK2 servomotors – the dynamic and compact solution

Teamed up in a drive system with a SINAMICS S210 servo converter, SIMOTICS S‑1FK2 servomotors provide short control and positioning times, fast and precise control response to disturbances and stable closed-control with a high dynamic performance.

Depending on the specific application, two servomotor versions are available:

• SIMOTICS S-1FK2 High Dynamic: Highest dynamic response through a low inertia for highly dynamic applications with low moved masses.
• SIMOTICS S-1FK2 Compact: Precise, stable control with medium to high masses to be moved with medium moment of inertia.

• Highest dynamic response as a result of the low rotor intrinsic inertia and the high overload capability
• Space-saving design as a result of the optimized frame size with a high power density
• High precision as a result of the high-resolution 22-bit single turn or multiturn absolute encoder
• High IP64 degree of protection of the motor – can be optionally increased to IP65

SIMOTICS S-1FT2 servomotors – the optimizable motor solution  

The SIMOTICS S-1FT2 servo motor offers a variety of additional options to meet the diverse challenges of drive technology more precisely. For example, encoders with a high resolution of up to 26 bits improve system accuracy. For use in harsh environments, a higher degree of protection up to IP67 as well as various motor paint finishes are possible. New machine options such as higher rated speeds are also available. The SIMOTICS S-1FT2 servo motor is available in the High Dynamic and Compact moment of inertia versions. The High Dynamic variant offers a maximum dynamic response due to a low intrinsic inertia for applications demanding a high dynamic performance with low masses to be moved. The Compact variant features impressive and precise, stable closed-loop control of medium to high masses to be moved with a medium intrinsic moment of inertia.

• Highest accuracy using singleturn or multiturn absolute encoders with resolutions of up to 26 bits
• More robust in harsh and humid environments thanks to the motor’s expandable degree of protection up to IP67 and various coating options.
• Greater variety of winding designs compared to SIMOTICS S-1FK2 for higher speeds
• Highest dynamic response as a result of the low rotor intrinsic inertia and the high overload capability
• Space-saving design as a result of the optimized frame size with a high power density

SIMOTICS S-1FS2 Hygienic Design Servomotor – the solution for the food, beverage and pharmaceutical industries

SIMOTICS S-1FS2 servomotors complement the motor portfolio for the SINAMICS S210 servo drive system for special applications in the food, beverage and pharmaceutical industries, and plants and systems where standard SIMOTICS S-1FK2 and S-1FT2 servomotors are not sufficient. This stainless steel motor series for operation under strict hygienic conditions is available in four sizes in the power range 0.45 to 2 kW with torques from 3.1 Nm to 23.5 Nm.

• High IP66 / IP67 degree of protection for the complete motor, IP69k (30 bar) motor housing
• Suitable for cleaning in place processes (CIP) using commercially available cleaning agents
• Meets the requirements of the pharmaceutical and food industry: 1.4404 stainless steel enclosure, EPDM seals, bearing grease with NSF H1 approval
• Design according to EHEDG guidelines
• High accuracy thanks to high-resolution 22-bit multiturn absolute encoder
• Shaft and flange compatible with SIMOTICS S-1FK2 and S-1FT2 servomotors

SIMOTICS S-1FK2 and S-1FT2 planetary servo gearmotors – the pre-assembled geared motor solution 

SIMOTICS S-1FK2 and S-1FT2 servo planetary gearmotors enable the highest cycle rates with a lightweight and low-inertia gearbox design, or inertia adjustment for precise movement of heavy loads.
These geared motor drives can be perfectly adapted to the application as there are a wide range of gearbox ratios and gearbox sizes. Based on the digital twin of the geared motors provided in the TIA Selection Tool, thermal dimensioning is just as simple as for a servomotor.

• Gearbox NRB/NRBW
  The NRB(W) is the lightest gearbox with the highest power density. As a result of its low-friction bearing design, it has a low intrinsic temperature rise and is suitable for high speeds.
• Gearbox NRK / NRKW
  As a result of their large output bearings, NRK(W) gearboxes are suitable for higher radial and axial forces. Thanks to their low inner friction, these gearboxes are also suitable for higher speeds.
• Gearbox  NLC / NLCW
  As a result of their pretensioned tapered rolling bearings, the NLC(W) gearbox has a high degree of stiffness, and is the perfect choice for high radial and axial load levels. These gearboxes are protected against dust and water thanks to their IP65 sealing system.

Advantages

• Optimum adaptation of the torque-speed or the mass moment of inertia relationship between the motor and load
• Pre-assembled, tested and ready-to-run servo geared motor solutions
