Overview
SIMOTICS T-1FW3 complete torque motors
The SIMOTICS T-1FW3 complete torque motors are water-
cooled, high-pole (slow running) permanent magnet synchro-
nous motors. The operating characteristics are comparable to
those of regular synchronous motors.
The motor spectrum comprises 3 external diameters in various
shaft lengths as well as 3 different shaft designs.
•
Hollow shaft (not available in the high-speed design
1FW3120)
- For infeed of cooling and heating media, measurement
cables, etc.
- Motors with various lengths can be connected to the
machine shaft
•
Plug-on shaft with integrated shaft centering
- Simple and quick installation as a result of the integrated
shaft adapter with centering
- Optimized clamping element
- Easy encoder replacement (safety-capability)
- Longer bearing lifetime
•
Solid shaft
- Simple replacement of a geared motor without having to
change the connection to the machine
- Easy encoder replacement (safety-capability)
The SIMOTICS T-1FW3 compact complete torque motors are
flanged onto the machine using the specially-developed stator
torque arms. The rotor is coupled to the machine shaft using the
clamping element that will be supplied if required. This results in
a perfectly rigid drive train that can be optimally controlled.
The SIMOTICS T-1FW3 complete torque motors can be com-
bined with the SINAMICS S120 drive system to create a power-
ful, high-performance system. The integrated encoder systems
for speed and position control can be selected depending on
the application.

■
Application
The SIMOTICS T-1FW3 complete torque motors were developed
as direct drives. These direct drives form a compact drive unit
where the mechanical motor power is transferred directly to the
driven machine without any mechanical transmission elements.
•
Extruder main drives
•
Worm drives for injection molding machines
•
Roll drive
• Winder
•
Fleece folding machines
•
Pull-roll drives for foil drawing machines
•
Stretch, calender, casting, and chill rolls
•
Dynamic positioning tasks, e.g. rotary tables, clocked
conveyor belts
•
Replacing hydraulic motors
•
Roll drives in paper machines
•
Cross-cutter drives for continuous material webs,
e.g. paper, textiles, metal sheet
•
Wire-drawing machines
