Overview
SIMOTICS S-1FT7 motors, forced ventilation, water cooling, and
natural cooling
The SIMOTICS S-1FT7 servomotors are permanent-magnet
synchronous motors with very compact dimensions and an
attractive design.
The S-1FT7 motors fulfill the highest standards in terms of
dynamic performance, speed setting range, shaft and flange
accuracy. They are equipped with state-of-the-art encoder
technology and optimized for operation on our fully digital drive
and control systems.
Natural cooling, forced ventilation, or water cooling are available
as cooling methods. With the natural cooling method, heat is
dissipated through the surface of the motor. With the forced
ventilation method, heat is forced out by means of built-on fans.
The water cooling method achieves maximum cooling, thereby
ensuring that the motor can be operated at maximum output.

Extremely high efficiency
SIMOTICS S-1FT7 Compact motors
S-1FT7 Compact motors have a low torque ripple so that they are
ideal for use in machine tool applications that require extremely
high surface quality and optimum machining results. Thanks to
their compact dimensions, they can be installed in confined
spaces.
SIMOTICS S-1FT7 High Dynamic motors
S-1FT7 High Dynamic motors have very low rotor moments of
inertia to achieve extremely good dynamic performance and
very short cycle times. The motors are available with forced
ventilation or water cooling and have high continuous output
ratings as a result.
■
Application
•
High-performance machine tools
•
Machines with stringent requirements in terms of dynamic
performance and precision, e.g.:
- Packaging machines
- Foil extractor machines
- Printing machines
- Handling equipment

More information
Some SIMOTICS S-1FT7 Compact motors are available as core
types. These core types can be express delivered as replace-
ment motors in the event of plant outages and offer the advan-
tage 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.
