FAQs
Install requires proper Exd-rated wiring, top-entry terminal box alignment, and adherence to IP66 sealing practices. Ensure supply uses Voltage Code S and that mounting is on a stable, vibration-damped base. The 280 frame and cast iron housing support secure mounting, while the Exdb protection provides explosion protection in hazardous areas. Regular checks of bearing condition (6316/C3) and insulation (ICLF) maintain safety margins.
Yes. This motor is designed for IE2 efficiency, with a 2-pole configuration suitable for steady-speed or fixed-speed drives. Its voltage code S simplifies integration with standard mining power systems, and the motor’s robust frame supports reliable operation when paired with VFDs or constant-speed drives, while maintaining compliance with S1 duty in demanding loads.
Key certifications include Exdb flameproof protection for hazardous atmospheres, IP66 ingress protection, and IC411 insulation class. The motor is suitable for mining and heavy industry, supports S1 duty, and aligns with high safety and reliability standards essential for underground operations and surface plants alike.
Best-suited for flameproof mining motors and other hazardous-location drives, especially where rugged cast iron construction, IP66 protection, and Exd certification are required. Use cases include conveying, extraction, pumps, and fans in mines, steel plants, and chemical facilities where explosion protection and durable performance are critical.
Expect higher uptime and lower maintenance costs due to the rugged 6316/C3 bearings, cast iron frame, and long insulation life (ICLF). The motor’s reliable Exd protection reduces downtime in hazardous zones, while IE2 efficiency lowers energy costs. With predictable service intervals and compatible spare parts, the total cost of ownership improves over the motor’s lifecycle.
