Overview

Built-in SIMOTICS T-1FW6 torque motors are designed as built-in motors for use in low-speed
direct drives with a high torque output.
These built-in torque motors are liquid-cooled, permanent-magnet-excited, high-pole-
number three-phase synchronous motors with hollow-shaft rotors. 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 9 frame sizes (or external diameters), each with at least 4
different axis lengths. Most of the motors are available for at least two different speed
ranges. Most of the stators and rotors are equipped with flanges at both ends with centering
surfaces and tapped holes, which allow them to be integrated into a machine.

General properties of the motors
• High torque from a compact design and low envelope dimensions
• High overload capability (factor 1.4 to 2.2)
• The maximum motor current is adapted to the Motor Modules of the SINAMICS S120 drive
system
• Water cooling to increase the rated power and to minimize the thermal transfer to the overall
machine assembly
• Cable outlet, axial, radial towards the outside or tangential for most frame sizes
• Directly coupled to the machine using flanges
• High degree of availability as there are no gearbox components in the drive train that are
subject to wear
