FAQs
Key installation considerations include the top terminal box layout for easy wiring, Exdb flameproof protection for explosion-prone zones, and IP66 sealing to resist dust and water ingress. The 250 frame with cast iron housing and IMB3 IM1001 mounting supports stable alignment in rugged sites, while bearing choices (6315/C3 and 6313/C3) reduce vibration and wear during long service runs.
IE2 efficiency, with full-load around 89.8%, translates to meaningful energy savings during continuous operation. This reduces electrical bills and heat generation, improving drive reliability and reducing cooling demands in underground or remote mining locations where power is costly and maintenance windows are limited.
Yes. The motor is rated for up to 1000 m altitude and ambient temperatures of 40 °C, supported by ICFL insulation and robust cast-iron construction. The combination of insulation class and flameproof protection ensures reliable performance in demanding environments where standard motors may struggle with heat and electrical stress.
The motor carries Exdb flameproof protection, IP66 ingress protection, and IC411 insulation, plus IE2 efficiency for performance standards. These certifications align with safety and energy regulations in mining, petrochemical, and other hazardous industries, helping meet mine safety, industrial hygiene, and electrical code requirements.
Long-term benefits come from a cast iron frame, high-quality bearings (6315/C3 and 6313/C3), IMB3 IM1001 mounting, and a top terminator box design that simplifies servicing. The Exdb/Exd protection reduces fault exposure in hazardous areas, while the robust construction and standardized dimensions support predictable maintenance, longer mean time between failures, and easier spares management.
