FAQs
For safe, compliant installation in explosive environments, ensure Exdb flameproof protection is maintained, connect via the top-entry terminal box, and secure the cast iron 315 frame to vibration-friendly bases. Use proper gland seals and ATEX/IECEx guidance to maintain IP66 integrity and insulation performance (ICLF). Ensure mounting is level and within the 1000 m altitude and 40 °C ambient limits for reliable cooling and long life.
IE2 efficiency translates to lower energy consumption under full-load and partial-load conditions. With full-load efficiency around 94.9% at 50 Hz, you’ll see reduced energy bills over the motor’s life, especially in continuous-process and high-duty-cycle applications. This also correlates with cooler running temperatures, potentially extending bearing life and reducing auxiliary cooling requirements.
Yes. The motor’s Exdb flameproof protection and IP66 rating are specifically designed for hazardous locations, including mining conveyors and processing lines. The 315 frame, 2-pole design, and robust IMB5 IM3001 construction support high-start torque and reliable operation under heavy loads, while the 1000 m altitude tolerance ensures performance across varied mining elevations.
This motor features Exdb flameproof protection, IP66 ingress protection, and ICFL insulation suitable for hazardous area installations. While CE marking specifics aren’t listed here, the Exdb designation aligns with ATEX/IECEx compliance, and IC411-like insulation class indicates suitability for demanding ambient conditions. Always verify local regulatory acceptance for your project scope.
The 6316/C3 bearings and cast iron frame, combined with sealed Exdb protection and IP66, reduce maintenance frequency and extend service life in dusty, wet sites. ROI benefits come from energy savings (IE2), lower downtime risk, and fewer spare-part interventions. Expect longer intervals between bearing reseals and easier field servicing due to the top-entry terminator box.
