FAQs
Installation requires adherence to explosion-protection standards (Exdb), IP55 sealing, and proper connection to a suitable power source. Use the D-End top termination box for wiring access, ensure correct mounting on a cast-iron 355 frame, and verify bearing fit (6322/C3 and 6316/C3). Plan for safe lifting due to the motor’s substantial weight and confirm compliance with local ATEX/IECEx requirements.
The motor is rated IE3, with full-load efficiency around 96.0% at 100% load and 96.0% at 75% load; at 50% load the efficiency is 95.4%. This performance delivers meaningful energy-cost reductions in continuous-duty applications, helping to lower operating expenses in large-scale process plants.
Yes. The motor is designed for continuous operation under S1 duty, meaning it can run at a constant load without interruption. This suits steady-state pumps, fans, and conveyors in hazardous environments, where consistent torque and reliable cooling are essential for long-term plant performance.
Exdb flameproof protection provides a robust enclosure designed to prevent ignition in explosive atmospheres. The motor carries Gas Group IIB and IP55 rating, along with IC411 insulation and an insulation class ICLF, enabling safe operation in hazardous zones while meeting stringent industry standards.
The motor uses a 355 frame made from cast iron, with bearings 6322/C3 and 6316/C3 and an IMB5 IM3001 mounting class. Termination is via a D-End top box, which simplifies wiring in tight spaces. Expect a substantial installation footprint and plan for a grounded foundation to support its 2330 kg net weight.
