Overview

Naturally cooled built-in SIMOTICS T-1FW6 torque motors are designed for use in low-
speed direct drives with a high torque output.
They are three-phase, permanent magnet synchronous motors with hollow-shaft rotors with
a high number of poles. The motors are delivered as components that are subsequently
built-in. When delivered, the stator and rotor are kept together using transport locks and the
rotor is protected using a spacer film. For a complete drive unit, bearings and rotary encoder
are required.
The product range includes 2 frame sizes (or external diameters), each with 5 different axis
lengths. The stators are equipped with flanges at both ends with centering surfaces and
tapped holes, which allow them to be integrated into machines. The rotors have mounting
and centering surfaces with tapped holes at both ends.
The motors are designed for the SINAMICS S120 drive system.
You can use Motor Modules in the "blocksize", "booksize" or "chassis" formats.
Accuracy
The accuracy of a direct drive with torque motor is governed by the:
● Mechanical design of the machine
● Control technology used
● Resolution and measuring accuracy of the encoder
Mechanical system
The potential machining accuracy of a drive system with torque motor is influenced by the:
● Mechanical rigidity and noise immunity of the drive system
● Running smoothness
The running smoothness in the axial and radial direction depends on the bearing version and
its accuracy. The requirements here can be fulfilled by means of a suitable axes design.
