Exdb flameproof protection is a core feature of the 3GJM224220-BEK motor, enabling safe operation in underground hazardous zones where gas or dust explosions are a risk. It reduces ignition risk, supports compliant installations, and lowers insurance burdens for mining operations. The business impact is clear: safer environments with fewer incidents translate to higher productivity and longer asset life on heavy-duty conveyors, crushers, and pumping systems. The motor’s IE3 efficiency class further lowers operating costs by delivering high efficiency across full and partial loads, which is critical for continuous mining processes and long-run reliability. IP66 enclosure and IC411 insulation provide robust protection against dust, water ingress, and high ambient temperatures, extending service intervals in harsh environments. The 22 kW, 8-pole, 500 V footprint aligns with common mine-site drives and reduces integration risk for retrofit projects. IMB5/IM3001 mounting compatibility and a cast-iron frame 225 ensure vibration resistance and straightforward installation, lowering maintenance complexity for OEMs and service teams. In practice, operators gain predictable performance, reduced downtime, and easier regulatory compliance while maintaining a lean spare-parts strategy for critical spares.

FAQs
The motor supports IMB5/IM3001 mounting and uses a D (Delta) connection with a 500 V, 50 Hz supply. Plan for a frame size 225 housing, top terminator box, and ensure the environment meets IP66 and ambient temperature requirements up to 40°C. Verify clearance for an MMS-style installation and use appropriate torque values from ABB integration guidelines.
It delivers 22 kW at 500 V and 50 Hz with 8 poles, in IE3 efficiency class. Full-load efficiency is 90.6% (100% load), with 75% and 50% partial-load efficiencies around 91.6% and 91.5%, respectively, providing strong energy savings in variable-load mining applications.
Yes. It features Exdb flameproof protection, IP66 ingress protection, and IC411 insulation, making it appropriate for hazardous underground zones in mining. The design supports Group I mining duty and IMB5/IM3001 mounting, aiding regulatory compliance and safe operation in explosion-risk environments.
The motor's net dimensions are 879 mm in length, 375 mm in width, and 573 mm in height. Net weight is 448 kg, with a gross weight of 458 kg, and it uses a cast iron frame (225) for robust mechanical strength and vibration resistance.
High IE3 efficiency reduces energy bills in continuous mining operations, while the rugged flameproof enclosure and robust bearings limit downtime and maintenance costs. The Exdb protection and IC411 insulation extend service intervals in harsh environments, delivering lower total cost of ownership for mining OEMs and operators.
