FAQs
Installation should begin with proper assessment of the Exdb protection requirements for the plant and gas group IIB. Use the D-End top termination access, install the flameproof enclosure per IEC/EX standards, and verify IP55 sealing. Ensure correct grounding and use certified wiring practices for hazardous areas. Due to the 315 frame and cast iron construction, confirm alignment and coupling with compatible gearboxes and driven equipment.
This motor is rated IE2 efficiency. In rated full-load (100%) conditions the efficiency is 91.6%. At 75% partial load the efficiency remains 91.6%, and at 50% partial load it is approximately 90.8%. These figures support energy savings across continuous and variable-speed applications typical of conveyors, pumps, and mixers in hazardous facilities.
Yes. The motor features IP55 ingress protection and Exdb explosion protection suitable for IIB gas groups. This makes it appropriate for hazardous environments such as chemical plants, refineries, and mining operations where both protection class and explosion protection are regulatory requirements, while maintaining reliable performance and reduced maintenance needs.
The motor uses a 315-frame, cast-iron construction designed for robust, long-life operation in demanding spaces. With the D-End top termination, installation and wiring are simplified, and compatibility with standard 315-frame couplings and gearboxes is straightforward. Ensure compatible mounting feet, shaft alignment, and appropriate vibration isolation to maximize service life in harsh environments.
Maintenance benefits arise from the rugged cast-iron frame, high-quality bearings, and flameproof construction, which reduce unexpected downtime. The IE2 efficiency lowers energy costs over the motor’s life, contributing to a favorable return on investment when deployed across continuous-drive lines in hazardous areas. Regular inspection of bearings, seals, and flameproof enclosures remains recommended to sustain reliability.
