Exdb flameproof protection is a core feature of this motor, enabling safe operation in Zone 1/2 hazardous environments. By containing arc and heat within the enclosure, it reduces ignition risk and supports regulatory compliance, enabling continued operation in chemical processing, oil refining, and mining applications. IP55 enclosure rating provides reliable protection against dust and water ingress, extending service intervals in dusty plants or wet environments, translating to lower maintenance and fewer unplanned outages in sectors like metals processing and cement. The IE4 efficiency class delivers measurable energy savings on continuous duty cycles such as conveyors and pumps, decreasing operating costs in large-scale automation runs. A cast-iron 355 frame with robust bearings (6322/C3 and 6316/C3) offers exceptional mechanical rigidity and long bearing life, reducing maintenance frequency. Reversible rotation and Ex-protected design support flexible layouts and faster installation in OEM assemblies, while IC411 insulation and 40 °C/1000 m operating envelopes enable safe, compliant operation across diverse sites. The combination of safety, efficiency, and rugged construction translates into lower total cost of ownership and improved plant throughput.

FAQs
This motor uses a standard 355 frame with a cast-iron enclosure and a D-end top terminator box, enabling straightforward mounting in fixed-base or adaptor configurations. The 4-pole design and reversible rotation support common conveyor, pump, and fan drives, while the durable housing tolerates up to 40 °C ambient and 1000 m altitude. Alignment and coupling should follow IEC standards for IEC 60072 and the 355 frame footprint to ensure optimal performance.
IE4 efficiency provides high electrical efficiency across operating points. At 50 Hz, full-load efficiency is documented at 97.4% (100%), with 75% load at 97.6% and 50% load at 97.5%. At 60 Hz, full load efficiency is 97.2%, with 75% load at 97.2% and 50% load at 96.8%. These figures translate to lower energy consumption for long-running applications like pumps or fans and reduced operating costs over the motor’s life cycle.
Yes. The motor is equipped with Exdb flameproof protection and an IP55 enclosure, making it suitable for hazardous environments. It also carries IC411 insulation and IE4 efficiency, with a gas group rating of IIB. These certifications support compliance with global hazardous-areas standards and help maintain safety and uptime in chemical, oil and gas, and mining applications.
Key references include Exdb flameproof protection, IP55 ingress protection, gas group IIB, IC411 insulation, and IE4 efficiency. Operating conditions specify ambient up to 40 °C and altitude up to 1000 m. The 355 frame, cast-iron construction, and reversible rotation support OEM integration, while the unit’s designation indicates suitability for S1 continuous duty and hazardous-zone installations.
The combination of high IE4 efficiency, robust cast-iron frame, and reliable bearings (6322/C3 and 6316/C3) reduces energy consumption and maintenance frequency. Exdb flameproof protection lowers risk-related downtime in hazardous environments, while IP55 further minimizes upkeep from dust and water ingress. These factors together shorten ROI cycles, extend service intervals, and improve plant throughput in demanding automation contexts.
