Exdb flameproof protection with IP66 enclosure provides a safe, dust- and water-resistant housing, reducing unplanned downtime in challenging mining conditions and protecting critical windings and bearings. This translates to safer operations and lower maintenance costs, enabling reliable performance for underground conveyors and bulk handling equipment. IE3 premium efficiency delivers meaningful energy savings at full and partial loads, cutting operating expenses while minimizing heat buildup, which extends bearing life and reduces cooling requirements for long-run performance. The 90 kW, 2-pole design in frame 280 supports high torque at start-up, improving driveability for crushers and fans; compatibility with IMB5/IM3001 mounting simplifies retrofits and new installations. The Ex protection and insulation class ICFL across 1000 m altitude and 40 °C ambient conditions ensures stable performance in variable mining climates, while the cast-iron frame and robust bearings (6316/C3) withstand harsh vibrational environments, lowering lifecycle costs. Reliability is reinforced by a D-end top terminator box and a proven 500 V 50 Hz supply, enabling straightforward integration into existing electrical infrastructure and spare-part compatibility for long-term maintenance planning.

FAQs
This motor is designed for IMB5/IM3001 mounting and features a D‑end top terminator box for simplified wiring. Ensure enclosure integrity and Exdb flameproof protection are maintained during installation, and align with the 2‑pole frame 280 mounting guidelines. Use appropriate anti-vibration clamps and verify connection to a 500 V, 50 Hz supply per the internal wiring diagram.
The motor delivers 90 kW output at 500 V and 50 Hz with IE3 efficiency. It operates under S1 duty, has IP66 ingress protection, and ICFL insulation. The Exdb flameproof protection suits hazardous environments, and the two-pole design provides robust startup torque for heavy-load mining drives such as crushers and conveyors.
Yes. The Exdb flameproof design and IP66 enclosure make it appropriate for underground and surface mining zones with explosive atmospheres. Its 1000 m altitude tolerance and 40 °C ambient rating support a wide geographic deployment, while IMB5/IM3001 mounting and 2‑pole configuration fit common mining equipment footprints.
Key certifications include Exdb flameproof protection, IP66 enclosure, and ICFL insulation class, ensuring compliance with hazardous-area motor requirements. The motor also aligns with mining industry practices for safety, energy efficiency (IE3), and robust mechanical design, with materials and mounting standards suited to IMB5/IM3001 configurations.
The IE3 efficiency class reduces energy costs across full-load and part-load operation, improving return on investment through lower electricity use and cooler operation. Combined with a cast iron frame, 6316/C3 bearings, and Ex protection, it offers extended service life and reduced maintenance cycles, delivering lower total cost of ownership for mining fleets.
