■
Overview
SIMOTICS T-1FW6 built-in torque motors with jacket cooling (on left),
naturally cooled (in center) and with integrated cooling (on right).
SIMOTICS T-1FW6 built-in torque motors are liquid-cooled or
naturally cooled multi-pole permanent-magnet AC synchronous
motors with a hollow shaft. The motors are supplied as built-in
components that are held together in the delivered state by
transport locks. For a complete drive unit, an additional bearing
and shaft encoder are required.
Each frame size is available in different axis lengths. Most stators
and rotors are equipped with flanges at each end with centering
surfaces and threaded holes for installation in the machine.
Please note that when SIMOTICS T-1FW6 direct motors (torque
motors) are used in fork heads for machine tools or robots, a
license for US patent US5584621 and the associated international
patent protection may be required. Please observe the national
and international licensing conditions when using direct motors so
that no infringements of industrial property rights occur.
