SEW FA27DRN71M4 Parallel Shaft Helical Gearmotor
The SEW FA27DRN71M4 is an ultra-slim, compact industrial parallel shaft helical gearmotor featuring a hollow shaft design[cite: 20]. Engineered for high mechanical efficiency, durable thermal performance, and narrow structural profile demands, it is widely utilized in light material handling conveyors, agitators, packaging machinery, and automated assembly drives[cite: 20].

Legacy SEW Motor Replacement & IE3 DRN Upgrade Guide
Obsolete SEW motor ranges (DT, DV, DRS, DRE) installed on F27 gearboxes can be seamlessly replaced with current IE3 Premium Efficiency DRN motors. Refer to the cross-reference mapping below for 1-to-1 retrofitting:
| Legacy Motor Code (Obsolete) | Efficiency Level | Current IE3 Replacement Motor | Rated Power (kW) | Mechanical Compatibility & Retrofit Notes |
|---|---|---|---|---|
| DT56S4 / DT56M4 / DT63K4 | IE1 / Standard Efficiency | DRN63MS4 / DRN63M4 IE3 Upgrade | 0.12 kW - 0.25 kW | Direct 1-to-1 flange & shaft match on F27 gearboxes. Lower energy loss. |
| DT71D4 / DV71D4[cite: 20] | IE1 / Standard Efficiency[cite: 20] | DRN71M4 IE3 Upgrade[cite: 20] | 0.37 kW - 0.55 kW | Identical mounting dimensions; direct drop-in replacement. |
| DT80N4 / DV80N4[cite: 20] | IE1 / Standard Efficiency[cite: 20] | DRN80M4 IE3 Upgrade[cite: 20] | 0.75 kW | Flange & shaft dimensions identical. Standard FA27 pairing. |
| DT90S4 / DV90S4 | IE1 / Standard Efficiency | DRN90S4 IE3 Upgrade | 1.1 kW | B5/B14 adapter compatibility preserved. Fully compliant with modern IE3 standards. |
| DT90L4 / DV90L4[cite: 20] | IE1 / Standard Efficiency[cite: 20] | DRN90L4 IE3 Upgrade[cite: 20] | 1.5 kW | Maximum power capacity pairing for F27 series. Replaces legacy DV90L4 seamlessly. |
Expert Selection & Retrofit Engineering Notes
When retrofitting an existing application featuring an obsolete DT56, DT63, DT71, DT80, or DV90 motor[cite: 20], 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.
