SEW W47DRN100L4 SPIROPLAN® Right-Angle Gearmotor
The SEW W47DRN100L4 is the high-torque flagship size in SEW's compact SPIROPLAN® right-angle gearmotor lineup[cite: 21]. Utilizing patented wear-free steel-on-steel spiral gearing technology enclosed in a robust, lightweight die-cast aluminum housing, the W47 provides superior mechanical efficiency, excellent thermal dissipation, and silent power transmission[cite: 21]. Available in versatile mounting configurations (foot, B5/B14 flange, solid shaft, hollow shaft with keyway, and TorqLOC® clamping system)[cite: 21], it is extensively deployed in material handling conveyors, rotary indexing drives, packaging equipment, and automated factory machinery[cite: 21].

Expert Selection & Retrofit Engineering Notes
When retrofitting an existing application featuring an obsolete DT63, DT71, DT80, DT90, or DV100 motor[cite: 21], 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.
