SIMOTICS servomotors
Overview

SIMOTICS S servomotors
The potential applications for SIMOTICS S-1FT7/S-1FK7 motors
are extremely diverse.
On machine tools, they are designated and used as feed
motors.
On production machines, e.g., printing, packaging and textile
machines, they are designated as synchronous servomotors.
Core types
can be supplied for certain motor types. These core
types can be express delivered as replacement motors in the
event of plant outages and offer the advantage of a quicker
spare parts supply. For this reason, core types should be used
for configuration wherever possible.
The selection and ordering data for the SINAMICS S120 Motor
Modules are based on the booksize format by way of example.
Other formats are also possible. The SIZER for Siemens Drives
engineering tool is available for detailed configuration
