Exdb explosion protection and IP66 enclosure provide rugged reliability in hazardous environments, reducing risk and enabling use in mining and surface facilities. The 280 frame in cast-iron housing delivers durability and robust heat dissipation, supporting long service life and lower maintenance costs in continuous operation. A 2-pole, S1 duty rating ensures stable, constant-speed operation for conveyors, crushers, and material handling equipment, translating into predictable process control and improved throughput. IE2 efficiency improves energy performance and reduces operating expenses over the motor’s life, with energy cost savings becoming tangible in long-term deployments. The top-terminator box enables easier electrical connections and faster installation, minimizing downtime during maintenance or retrofits. Combined with dimensionally compatible mounting and bearings (6316/C3), this motor offers straightforward alignment and reduced spares consumption. The Exdb and flameproof design supports compliance with strict mining regulations, while the compact frame and standard mounting simplify retrofits into existing lines.

FAQs
This motor uses a 280 frame with a cast-iron housing and a top termination box, making it compatible with existing 280-frame bases and common mounting designs. The 2-pole, S1 duty configuration supports continuous operation in conveyors and crushers. For retrofit projects, confirm shaft alignment, bearing fit (6316/C3), and clearance to avoid interference with nearby components.
Key specs include IE2 efficiency class, voltage code E, IP66 enclosure, and Exdb explosion protection. The motor is designed for 3-phase power with a 2-pole configuration, suitable for continuous duty (S1) in demanding environments, and operates at ambient 40 °C with up to 1000 m altitude.
Yes. The model features Exdb explosion protection and flameproof design, making it appropriate for mining environments where hazardous atmosphere classifications apply. Its IP66 rating further ensures ingress protection in dusty or wet mining areas, supporting safer operation of conveyors, crushers, and material handling.
Plan for top-mounted terminal connections, 280 frame mounting, and alignment with 6316/C3 bearings. Ensure adequate clearance for heat dissipation, verify ambient temperature does not exceed 40 °C in operation, and confirm the motor’s top-termination box location aligns with the control panel or junction box to minimize wiring length and simplify maintenance.
IE2 efficiency lowers energy costs during long-running cycles common in mining and processing plants, improving total cost of ownership. Exdb flameproofing reduces risk and potential downtime from hazardous atmospheres. Combined with a cast-iron frame and robust bearings, this motor delivers longer service life and reduced maintenance cycles in harsh environments.
