Design
The SIMOTICS T-1FW6 built-in torque motor comprises the
following components:
Stator
Version in 3-phase AC winding. The stator is generally designed
for operation with liquid cooling.
Rotor
Cylindrical hollow shaft made of steel with permanent magnets
fixed to the circumference.
If the main cooler and precision cooler are used together in a
cooling unit, a cooling connection adapter (accessory) can be
ordered separately for simpler connection.
Cooling types
The design of the cooling system is dependent on the size
(external diameter) of the motor.
Naturally cooled motors
Naturally cooled motors have the same dimensions as water-
cooled motors in frame sizes 1FW6050 and 1FW6060, but have
a lower continuous torque capability because they are naturally
cooled. They can be used for any application for which liquid-
cooled motors would be deemed undesirable or unnecessary. In
addition to their dimensions, their mechanical interfaces are also
compatible with those of water-cooled motors which means that
it is relatively easy to change the cooling method.

Motors with integrated single-circuit cooling
These motors have a ready-to-connect, integrated single-circuit
cooling system; they are compact and therefore suitable for easy
integration in a machine.
