The ideal solution for high-performance motion control applications
SIMOTICS S-1FK7servomotors

SIMOTICS S-1FK7 motors are permanent magnet excited synchronous motors which are available in the versions Compact, High Dynamic and High Inertia. The motors are characterized by superior overload capability, ruggedness and compactness. The connection via rotatable connectors and preassembled cables ensures a flexible, fast and safe connection to the converter.

Servomotors for every motion task
Whether positioning, angular synchronism, cyclic drive or path control in machine tools: with SIMOTICS servo motors from Siemens, you benefit from high dynamics, precision, compactness and ruggedness.

•High degree of efficiency and triple overload capability
•Shock and vibration-resistant due to mechanically isolated encoder connection
•Optionally with absolute encoder, incremental encoder or resolver
•Easy to assemble and service due to rotatable connector with quick-release fastener and exchangeable encoder
•Digital DRIVE-CLiQ interface with electronic rating plate for optimum connection to SINAMICS S120
•Optionally with different gear types and backlash-free holding brake
•Cooling methods: Natural cooling and forced ventilation

•Packaging machines
•Plastics and textile machines
•Printing machines
•Wood, glass, ceramics and stone working
•Robots, handling systems and conveyor technology
•Feed and auxiliary axes for machine tools

Overview of the product range
With our SIMOTICS S-1FK7 servomotors, you can choose between three inertial designs depending on the requirements for dynamics, control behavior, accuracy and space.
