SEW FA77DRN132S4 Parallel Shaft Helical Gearmotor
The SEW FA77DRN132S4 is a medium-to-heavy industrial parallel shaft helical gearmotor featuring a hollow shaft design[cite: 19]. Engineered for high mechanical efficiency, excellent overhung load tolerance, and narrow structural profile demands, it is widely deployed in material handling conveyors, industrial mixers, wastewater agitators, and automated machinery drives[cite: 19].

Expert Selection & Retrofit Engineering Notes
When retrofitting an existing application featuring an obsolete DT80, DT90, DV100, DV112, or DV132 motor[cite: 19], upgrading to an IE3 DRN motor ensures complete dimensional interchangeability while substantially reducing operating temperatures and energy costs. Simply send us your existing SEW serial number or nameplate code (including options like BE brake, TF thermistor, or RS backstop), and our engineering team will provide a 100% compliant replacement specification and quotation.
