FAQs
Install the 3GJM281220-BEK using IMB5 or IM3001 mounting, with a D-connection configuration and a 500 V supply at 50 Hz. The motor is two-pole and rated for IP66 and Exdb protection, suitable for hazardous areas. Ensure adequate space for ventilation and confirm mounting hardware compatibility with the 280 frame.
At 50 Hz, the motor meets IE3 efficiency. Full-load efficiency is 94.7%, with 75% load at 94.7% and 50% load at 94.0%. These figures confirm high energy efficiency during continuous operation, contributing to lower running costs in long-duty mining applications.
Yes. The motor is designed for mining environments, featuring Exdb flameproof protection, IP66 enclosure, and a rugged cast-iron frame with IMB5/IM3001 mounting. Its 2-pole design delivers reliable performance for conveyors, crushers, and material-handling equipment in both underground and surface mining.
The motor provides Exdb explosion protection, IP66 ingress protection, and ICFL insulation, with IE3 efficiency and IMB5/IM3001 mounting. These protections ensure safe operation in explosive atmospheres, harsh dust and water exposure, and compatibility with standard mining equipment installations.
Expect lower operating costs due to IE3 efficiency, and a longer service life from a cast-iron frame and robust bearings (6316/C3). The Exdb protection and IP66 enclosure minimize downtime in harsh environments, while IMB5/IM3001 mounting simplifies maintenance access and spare-part availability, delivering a favorable return on investment over the motor’s lifecycle.
