Motor Module for SINAMICS S120 Drives
The Siemens 6SL3320-1TG31-5AA0 is a SINAMICS S120 Single Motor Module designed as a spare part for the drive family. It takes a DC-link input from a Smart Line Module or Active Line Module and delivers a 3-phase AC output to a single motor. Rated for 150 A output, it handles motors in the 500 V to 690 V AC range — typical for medium-voltage industrial applications like conveyors, pumps, and fans in heavy process lines.
DC Input and AC Output Ratings
Input accepts a DC bus voltage from 675 V to 1035 V DC. Output delivers 500 V to 690 V three-phase AC at 150 A. The wide DC input window means it can operate on both 600 V and 700 V class DC buses without a buck-boost converter. Built-in internal air cooling handles the thermal load — no external fan unit required. The module includes a DRIVE-CLiQ cable for direct connection to the control unit (CU) for cyclic real-time data exchange.
Siemens lists this part at a mature lifecycle stage. It remains in the active catalog but is not a current-design-in target — Siemens continues to manufacture it for installed-base support and spare-part obligations.
