SIMOTICS T torque motors
Torque motors for the gearless direct drive of rotary axes
Whether as complete or built-in torque motors: Optimized for high torques at low rated speeds, the SIMOTICS T motors with their high precision and
dynamics are very convincing. In combination with the SINAMICS S120 drive system and the SIMOTION Motion Control System, the SIMOTICS T
torque motors provide an optimally tuned rotary direct drive system for the requirements of modern mechanical engineering. Complete torque
motors are used in converting applications, e.g. as extruder main drives or roller and winder drives; built-in torque motors are used, for example, in
rotary indexing machines, rotary tables, or for swivel and rotary axes.
Thanks to the omission of mechanical transmission elements such as gear units, the number of components susceptible to wear is reduced.
SIMOTICS T-1FW3 complete torque motors
The SIMOTICS T-1FW3 complete torque motors are water-cooled, high-pole (slow running) permanent magnet
synchronous motors. The 1FW3 range of motors comprises three external diameters in various shaft lengths as
well as three different shaft versions (hollow shaft, plug-on shaft and solid shaft).
• Shaft heights: SH 150 ... 280
• Degree of protection: IP54 (hollow shaft), IP55 (plug-on and solid shaft)
• Rated power: 2.8 ... 435 kW
• Rated torque: 95 ... 7000 Nm
For further information see Catalog D 21.4 – Chapter SIMOTICS linear and torque motors.
SIMOTICS T-1FW6 built-in torque motors
SIMOTICS T-1FW6 built-in torque motors are liquid-cooled or naturally cooled multi-pole permanent-magnet AC
synchronous motors with hollow shaft. The motors are supplied as built-in components; for a complete drive unit
an additional bearing and rotary encoder are required. Most stators and rotors are equipped with flanges at each
end with centering surfaces and threaded holes for installation in the machine.
• External diameter: 159 ... 730 mm (6.26 ... 28.7 in)
• Degree of protection: IP23
