Installation Guide
- Check the nameplate before wiring. Also, match voltage and frequency to your supply.
- Use the IM B35 foot and flange mount as standard. However, choose IM B3, IM B5, or IM B14 if needed.
- Align the motor carefully with the driven machine. Otherwise, poor alignment causes vibration and bearing wear.
- Keep the cooling fan and fins clean. In addition, blocked airflow reduces motor life.
- Protect the motor from moisture and dust. IP55 is standard. For harsh areas, order IP66.
- For inverter operation, follow VPWM settings per IEC 60034. Consequently, you avoid drive faults.
Setup and Maintenance Convenience
- Terminal box access is simple. Therefore, wiring changes are quick.
- Star/delta changeover supports 230/400 V or 400/690 V supply per size. As a result, you gain flexible supply options.
- Class 155 (F) insulation handles heat well. Class 180 (H) is available on request.
- Check bearings and lubrication at regular intervals. Also, inspect fan cover and cooling channels during service stops.
- Store between -15 and +70 °C in a dry, non-condensing place. In short, keep the motor protected before installation.

Expert Review
The DRN100LS4 is a strong choice for continuous industrial duty. Its IE3 efficiency cuts energy loss. Moreover, the TEFC design resists dust and moisture. The motor pairs well with SEW gearboxes and inverter drives. However, it is not a high-overload motor for extreme shock loads. For heavy starts, check the duty cycle and thermal margin. Overall, it is a reliable workhorse for plant automation.
Manager’s Insight
Buyers often ask for IE3 motors that fit existing SEW systems. The DRN100LS4 meets that need. In addition, it replaces older DRS and DR2S units in many cases. Stock is moving fast because 2.2 kW is a common size. If you need IP66 or class H insulation, order early. Meanwhile, use the 12 to 24 hour dispatch window for urgent line repairs.
