Feature → Business Impact → Application: Flameproof Exdb protection paired with IP66 enclosure and IE3 efficiency delivers safer operation in explosive atmospheres while reducing energy consumption and heat load. In mining applications such as conveyors and processing lines, this reduces downtime and maintenance costs, while meeting stringent safety and environmental standards. Application: ideal for surface and underground mining equipment operating in harsh ambient conditions. Feature → Business Impact → Application: 8-pole design and Y-configuration at 400 V 50 Hz ensure robust starting torque and stable operation across load variations common in material handling tasks. Application: mine hoists, crushers, and pumps. Feature → Business Impact → Application: Cast-iron frame (280) with bearings 6316/C3 and IMB3/IM1001 mounting provide superior vibration resistance and long service life in dynamic plant environments. Application: equipment with high vibration and peak load cycles. Feature → Business Impact → Application: Top terminator box and compact IMB3 mounting simplify installation, wiring, and serviceability, reducing commissioning time and spares inventory. Application: retrofits and new builds requiring reliable, compliant installations. Feature → Business Impact → Application: Operating at altitudes up to 1000 m and ambient up to 40 °C supports consistent performance in diverse mining locations. Application: remote sites with variable cooling and ventilation. Overall, the combination of Exdb flameproof protection, IE3 efficiency, and rugged construction translates to lower total cost of ownership, improved uptime, and easier procurement for mining and heavy industry projects.

FAQs
The motor uses IMB3/IM1001 mounting with a top terminator box for straightforward wiring. It is configured for a Y connection at 400 V and 50 Hz, featuring 8 poles and a robust cast-iron frame (size 280). This combination simplifies integration with existing mine drive assemblies and minimizes installation time.
At 50 Hz, IE3 full-load efficiency is 92.2%, with partial-load values around 92.1% (75% load) and 90.7% (50% load). The motor operates under S1 continuous duty, with a design suited for mining duty cycles. Altitude up to 1000 m and ambient temperatures up to 40 °C are factored into cooling and performance expectations.
Yes. The 45 kW, 8-pole, 400 V, IE3-efficient motor features Exdb flameproof protection and IP66 enclosure, making it suitable for mining conveyors, crushers, and pumps. IMB3/IM1001 mounting and robust mechanical construction support continuous operation in vibration-heavy environments typical of mineral processing and material handling.
Key protections include Exdb flameproof protection and IP66 enclosure. Insulation class is ICF/LF, with IC411 data, and duty is S1. The motor is designed for hazardous locations and harsh sites, with mounting and insulation rated for mining applications and a 1000 m altitude rating. Origin is Finland (FI), supporting quality and traceability.
The combination of premium IE3 efficiency and Exdb flameproof protection reduces energy costs and mitigates risk of hot spots or sparks in explosive environments. Rugged cast-iron construction and bearings (6316/C3) extend service life, lowering maintenance frequency. IMB3/IM1001 mounting simplifies spare-part logistics and on-site servicing, improving overall ROI for mining operations.
