FAQs
This motor is designed with Exdb flameproof protection and IP66 enclosure, simplifying electrical wiring and cabinet integration in hazardous zones. Use proper Ex-rated connectors, follow the top-termination box access for wiring, and ensure local compliance with Ex standards. Verify mounting and alignment for the 315 frame and 2-pole configuration to optimize startup torque and vibration control.
It provides IE2 energy efficiency, IP66 ingress protection, IC411 insulation, and Exdb flameproof protection, suitable for S1 duty in explosive environments. The motor also supports 1000 m altitude operation and 40 °C ambient temperature, making it compliant with common mining and heavy-industrial specifications.
Yes. With an altitude rating of 1000 m and an ambient temperature rating of 40 °C, the motor maintains reliable performance and thermal stability in high-altitude mining sites, while the Exd protection ensures safety in explosion-prone zones.
Schedule regular bearing and enclosure inspections, verify Ex-rated connections, monitor insulation resistance, and maintain cooling pathways. Cast-iron frame and robust bearings (6316/C3) support long service intervals in rugged environments. Routine checks reduce unexpected downtime and help sustain IE2 energy efficiency over the motor’s life.
IE2 efficiency lowers energy consumption during continuous S1 operation, translating to meaningful energy savings over the motor’s life. Coupled with Exdb protection and durable construction, you gain lower maintenance costs, less unscheduled downtime, and a faster payback in hazardous-area mining applications.
