Motor Description 1
1.1 Features
Overview
1FT6 motors are compact permanent-magnet synchronous motors. 1FT6 motors with
integrated encoders can be operated with the SINAMICS S120 drive system.
The fully digital control system of the SINAMICS S120 drive system and the encoder
technology of the 1FT6 motors fulfill the highest demands in terms of dynamic performance,
speed setting range, and rotational and positioning accuracy.
The motors are primarily designed for operation without external cooling, and the heat is
dissipated through the motor surface. The heat that is predominantly generated in the stator
winding and in the stator core can be directly dissipated via the good thermal coupling to the
motor enclosure. The concept of brushless, permanent-field synchronous motors shows its
special merits here.
