SEW W30DRN80M4 SPIROPLAN® Right-Angle Gearmotor
The SEW W30DRN80M4 is a powerful yet compact right-angle gearmotor incorporating SEW's patented SPIROPLAN® wear-free steel-on-steel spiral bevel gearing technology[cite: 26]. Housed in a lightweight die-cast aluminum casing, the W30 offers higher torque output and superior mechanical efficiency compared to smaller SPIROPLAN® units[cite: 26]. Featuring versatile mounting styles (foot, B5/B14 flange, solid shaft, hollow shaft with keyway, and TorqLOC® clamping system)[cite: 26], it is extensively deployed in material handling conveyors, rotary indexing drives, food packaging lines, and automated factory machinery[cite: 26].

Expert Selection & Retrofit Engineering Notes
When retrofitting an existing application featuring an obsolete DT56, DT63, DT71, or DT80 motor[cite: 26], 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.
