FAQs
The motor uses a Delta (D) connection suitable for 400 V networks. Ensure terminal wiring aligns with the delta configuration, verify correct phase sequence, and secure the terminator box at the Top as specified. Use appropriate protective earth connections and confirm enclosure IP66 integrity prior to startup. This simplifies commissioning and reduces risk of miswiring during retrofit projects.
Yes. Exdb flameproof protection combined with IP66 ingress protection provides a robust barrier against dust, water, and explosive atmospheres typical of underground mining. The insulation class ICFL supports thermal management in 40 °C ambient conditions, ensuring safe operation across altitudes up to 1000 m. This makes it a reliable choice for safety-compliant mining drives and processing equipment.
IE3 designation reflects premium efficiency. At 50 Hz, full-load efficiency is 93.7%, with 75% and 50% loads near 94.0% and 93.7% respectively. At 60 Hz, full-load efficiency improves to 94.0%, with 75% around 94.2% and 50% near 93.4%. These figures translate to meaningful kWh savings over continuous operation, reducing energy costs in fleet drives and increasing overall plant efficiency.
The motor uses Frame Size 200 with IMB5/IM3001 mounting and a Top terminator box, facilitating straightforward integration into existing drive assemblies and OEM equipment. This compatibility reduces adaptation time, minimizes structural changes, and helps maintain consistent alignment with shaft couplings and gearboxes, supporting faster deployment in mining conveyors and processing lines.
With a Cast Iron frame and bearings 6312M/C3 (NDE 6310M/C3), the motor is designed for rugged duty in harsh environments. The Exdb protection and flameproof design reduce ignition risks, while IC411 insulation and IP66 enclosure protect internal components. Regular inspection of bearings, seals, and terminal connections, along with periodic thermal monitoring, will help maximize uptime and extend service life in continuous mining applications.
