FAQs
This motor supports IMB5 and IM3001 mounting configurations with a D connection option, enabling straightforward integration with standard bases and couplings. The 8-pole, 280 frame size and cast-iron construction simplify alignment with existing systems, while maintaining robust performance in harsh environments. Compatibility with common VFDs also helps enable smooth starting and speed control for conveyors and pumps.
The motor features IP66 ingress protection and Exd flameproof protection (Exdb), with IC411 enclosure class. These ratings ensure safe operation in dusty, wet, and explosive environments typical of mining sites. Its IE3 efficiency rating further supports compliance with energy standards while reducing operating costs over the motor’s life.
Yes, it is designed for hazardous locations. It carries Exd flameproof protection (Exdb) and is rated IP66 for protection against dust and water ingress, with IC411 enclosure. It also complies with energy efficiency requirements via IE3. These attributes support safe, compliant operation in mining, chemical processing, and similar industries.
At 50 Hz, the motor operates at 500 V with an output of 45 kW and IE3 efficiency around 92.2% at full load. At 60 Hz, efficiency rises to about 92.4% full load. Ambient temperature is up to 40 °C, altitude up to 1000 m, and connection configuration is D. The motor is designed for continuous S1 duty.
Energy savings from IE3 efficiency reduce operating costs, while the rugged cast-iron frame, IP66/IC411 protection, and Exd flameproof design lower maintenance and hazard-related downtime. With durable bearings and a robust mounting system, you can expect longer service life and fewer unplanned outages, improving ROI in mining and heavy industry applications.
