Overview of the standard SIMOTICS T-1FW3 complete torque motors
The 1FW3 series was developed as direct drive. This direct drive is a compact drive unit
where the mechanical motor power is transferred directly to the driven machine without any
mechanical transmission elements. 1FW3 complete torque motors are water-cooled, high-
pole (slow running) permanent-magnet-excited synchronous motors. The operating
characteristics are comparable to those of regular synchronous motors.
The range includes 3 outer diameters with various shaft lengths. For shaft heights 150 and
200, the stator and rotor have a flange with centering edges and tapped holes at the DE that
allow them to be integrated into a machine.
The 1FW3 complete torque motor can be ordered with various shaft versions:
● Hollow shaft
● Plug-on shaft with integrated shaft centering
● Solid shaft
The various shaft versions allow highly flexible design and maintenance concepts to be
implemented. 1FW3 torque motors can be combined with the SINAMICS S120 drive system
to create a powerful, high-performance system. The integrated encoder systems for speed
and position control can be selected according to the application.

• Completely hollow shaft,
e.g. for feeding cool-
ant/heat, measuring ca-
bles etc.
• Motors with various
lengths can be mounted
on the machine shaft.
• Simple and quick instal-
lation as a result of the
integrated shaft adapter
with centering
• Simpler clamping ele-
ment
• Simple encoder re-
placement
• "Classic" motor installa-
tion
• Simplest overall solution
• Simple replacement of a
geared motor without
having to change the
connection to the ma-
chine
• Simple encoder re-
placement
