FAQs
Plan for IMB3/IM1001 mounting compatibility and a top-term block layout to simplify service access. Use the Y connection for balanced three-phase supply at 400 V, 50 Hz, with appropriate flameproof cable entries and sealing to maintain IP66 integrity in dust-prone or humid conditions.
IE3 efficiency reduces energy consumption during continuous operation, translating to lower kWh usage and cooler running temperatures. In practice, this motor delivers typical efficiency around 94% at full load, producing meaningful lifecycle cost savings in long-duty mining applications.
Yes. Designed for up to 1000 m altitude and ambient temperatures up to 40 °C, with a robust frame size 250 and IMB3/IM1001 mounting, it maintains torque and speed performance while ensuring reliable cooling and insulation in challenging climates.
The motor features Exdb flameproof protection and an IP66 enclosure, supporting safe operation in hazardous zones. These protections align with common mine safety practices for explosion protection and ingress prevention, helping you meet regulated installation requirements.
The combination of IE3 energy efficiency, reduced downtime due to rugged construction, and extended bearing life contributes to a favorable ROI. While exact payback depends on duty cycle and energy costs, the model is designed to minimize lifecycle costs through improved reliability and energy savings.
