FAQs
Installers should follow certified procedures for Exd motors. Use the top-mounted terminator box to minimize wiring in confined spaces, ensure proper enclosure sealing, and connect per the IECEx/ATEX guidelines. Verify IP66 integrity after assembly and secure a compliant cable entry with appropriate grommets. Routine checks should confirm bearing pre-load and shaft alignment to prevent premature wear in mining conveyors and other heavy-duty equipment.
At 50 Hz, Full Load efficiency is 93.9% with IE2 efficiency class, and at 60 Hz, Full Load efficiency remains high with 93.4% (IE2) while Partial Load values remain above 91%. The motor is a 2-pole design with a 225 frame, cast-iron construction, and a top-placed terminal box for straightforward installation in rugged environments.
Yes. The model is specified as a flameproof Exd motor (Exdb) for Group I mining environments and is designed to deliver reliable performance under S1 duty. Its enclosure, insulation, and protective features align with harsh mining site requirements, making it suitable for conveyors, crushers, and other demanding mining equipment.
Key certifications include Exdb flameproof protection, IP66 ingress protection, and ICFL insulation class. It supports Exd protection suitable for mining zones, Direction of Rotation: Both sides, and a 2-pole configuration. The unit carries a Finland origin with a robust cast-iron 225 frame and specific bearing types (6313M/C3, 6312M/C3) for extended service life.
The motor’s Ex protection, IP66 ruggedness, and IE2 efficiency reduce energy costs and downtime, improving overall OPEX. The top-terminal box simplifies maintenance and wiring in hazardous areas, while the cast-iron frame and premium bearings extend service life, lowering replacement and maintenance intervals in challenging mining environments.
