Overview

SIMOTICS T-1FW6 external rotor built-in 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. The motors are delivered as components that are
subsequently built-in. The stators and rotors are delivered separated and are integrated into
the machine construction by the machine manufacturer during installation. For a complete
drive unit, bearings and rotary encoder are required.
The type spectrum includes a frame size with 4 overall lengths. The stators and rotors are
equipped with flanges that have centering surfaces and tapped holes which allow them to be
integrated into the machine.
①
②
The motors are designed for the SINAMICS S120 drive system.
You can use Motor Modules of "blocksize" or "booksize" formats.
Accuracy
The accuracy of a direct drive with torque motor is governed by the:
• mechanical design, mechanical rigidity and bearings of the machine
• Control technology used
• Resolution and measuring accuracy of the encoder
