FAQs
Plan for IMB5/IM3001 mounting compatibility and top termination access. The 280 frame and 8-pole design necessitate suitable space, and the 500 V, 50 Hz supply must be matched to your switchgear. Ensure the drive system supports Exd-approved cables, with IP66 protection against dust and water ingress in harsh environments to maintain reliability.
IE3 premium efficiency reduces energy consumption across full-load and partial-load conditions, directly lowering operating costs. In 50 Hz operation, Full Load efficiency is around 91.8% with reasonable partial-load values, contributing to a lower cost of ownership over the motor’s life in continuous mining services.
Yes. The motor is Exd flameproof protected (Exdb) and carries IP66 sealing, making it appropriate for hazardous-area applications in mining and heavy industry where explosive atmospheres and harsh conditions prevail.
Best suited for surface and underground mining equipment such as conveyors, crushers, and grinding systems that require reliable 37 kW power, 8-pole torque, robust enclosure, and compatibility with ABB control architectures for safe operation in demanding environments.
A rugged cast-iron frame, precision bearings (6316/C3), and Exd protection contribute to longer service life and reduced maintenance downtime. Availability of IMB5/IM3001 mounting simplifies installation, while its IP66 rating and 1000 m altitude capability ensure stable performance in harsh mine conditions.
