SIMOTICS T-1FW3 complete torque motors

The SIMOTICS T-1FW3 complete torque motors are watercooled, high-pole (slow running) permanent magnet synchronous motors. The operating characteristics are comparable to those of regular synchronous motors.

The motor spectrum comprises 3 external diameters in various shaft lengths as well as 3 different shaft designs.

• Hollow shaft (not available in the high-speed design 1FW3120)
  • For infeed of cooling and heating media, measurement cables, etc.
  • Motors with various lengths can be connected to the machine shaft
• Plug-on shaft with integrated shaft centering
  • Simple and quick installation as a result of the integrated shaft adapter with centering
  • Optimized clamping element
  • Easy encoder replacement (safety-capability)
  • Longer bearing lifetime
• Solid shaft
  • Simple replacement of a geared motor without having to change the connection to the machine
  • Easy encoder replacement (safety-capability)

The SIMOTICS T-1FW3 compact complete torque motors are flanged onto the machine using the specially‑developed stator torque arms. The rotor is coupled to the machine shaft using the clamping element that will be supplied if required. This results in a perfectly rigid drive train that can be optimally controlled.

The SIMOTICS T-1FW3 complete torque motors can be combined with the SINAMICS S120 drive system to create a powerful, high‑performance system. The integrated encoder systems for speed and position control can be selected depending on the application.
