Exdb flameproof protection combined with an IP66 enclosure defines the core feature. This delivers safer operation in explosive atmospheres and supports ATEX/IECEx compliance, reducing the risk of ignition and costly downtime. It is ideal for mining conveyors, crushers, and other equipment where sealing and resilience against dust and moisture matter most. IE3 premium efficiency at 50 and 60 Hz translates into measurable energy savings and cooler operation. The motor’s efficiency data (Full Load around 94.1–94.5%) lowers running costs and reduces cooling loads in continuous S1 duty. This suits plants aiming to improve energy intensity targets while maintaining reliable torque. Robust mechanical design uses a cast iron frame, 280 frame size, and bearings 6316/C3 to withstand challenging mining conditions. IMB5/IM3001 mounting supports reliable installation and straightforward retrofits in existing facilities. The 400 V, 3‑phase supply and D‑connection configuration align with standard industrial power systems. Design supports altitude up to 1000 m and ambient temperatures up to 40 °C, making it suitable for open pit and underground sites with variable climates. IC411 insulation and Ex-protection (Exdb) meet strict safety standards, while IP66 ensures rugged protection against dust and water ingress. These features translate to longer service life and predictable maintenance cycles. Maintenance requirements are streamlined by IMB5 IM3001 mounting and a heavy-duty cast iron frame that tolerates harsh handling. The unit’s size and weight (about 806 kg net) reflect a design that tolerates long intervals between service interventions while preserving performance and uptime.

FAQs
Installers should plan for a D connection configuration with a 400 V 50 Hz supply and IMB5/IM3001 mounting. The unit is designed for IP66 dust and water resistance and Exdb flameproof protection, making it suitable for hazardous areas in mining. Ensure adequate clearance for heat dissipation and confirm ambient temperature and altitude within ratings (up to 40 °C and 1000 m) to maintain performance and warranty compliance.
Exdb protection provides intrinsic flameproof safety by containing ignition sources within the motor, reducing the risk of explosions in explosive atmospheres. This enables compliant operation in ATEX/IECEx zones, minimizes shutdowns, and supports safer maintenance procedures in underground or surface mining facilities.
Yes. The 3GJM283230-BDL is specified for up to 1000 m altitude and ambient temperatures up to 40 °C. Coupled with IC411 insulation and IP66 enclosure, the motor maintains performance and reliability in challenging mining conditions, including remote sites with limited cooling options.
Maximize uptime by inspecting bearings (6316/C3) for wear, ensuring proper shaft alignment, and verifying terminal connections within the terminator box at the D-End top. IMB5 IM3001 mounting is designed for reliable installation and straightforward service, reducing downtime during routine maintenance or retrofit projects.
IE3 premium efficiency typically delivers tangible energy savings over IE2 motors, particularly in continuous S1 duty with a full-load around 94.1–94.5% efficiency. For mining operations, these savings translate to lower running costs, reduced heat load, and improved electrical system efficiency without sacrificing torque or reliability.
