The flameproof IE3 rated 90 kW motor at 500 V delivers high efficiency under continuous mining duty. This premium efficiency reduces energy consumption and heat generation, driving lower operating costs while supporting longer service intervals. It’s well suited for demanding mining drives such as belt conveyors, crushers, and hoists in hazardous locations. Built on a rugged cast iron frame size 280, the motor supports IMB5/IM3001 mounting for stable, vibration-resistant installation. Bearings labeled 6316/C3 provide durable support with reduced shaft runout, helping protect connected gearboxes and couplings in dusty, high-vibration environments. The IP66 enclosure combined with Exdb protection delivers reliable operation in explosive atmospheres and adverse weather conditions, minimizing maintenance interruptions. With a 2-pole configuration at 50 Hz, the unit delivers steady torque for conveyors and hoists, and supports operation up to 1000 m altitude and 40 °C ambient. Insulation Class ICLF and IC411 data ensure reliable operation at elevated temperatures, extending service life in hot underground passages. Compatibility with ABB drive systems and standard mounting patterns enables quick retrofits and easy integration into existing mining fleets.
