FAQs
The 3GJM284220-BDL uses IMB5/IM3001 mounting, with a frame size 280 and a D-type connection configuration. It is designed for 400 V, 50 Hz systems and supports a 1 piece minimum order quantity. This combination ensures straightforward installation on standard bases and alignment with common mineral processing equipment.
At 50 Hz the motor delivers 45 kW output with IE3 efficiency. Full-load efficiency is around 92.2% and partial-load values stay above 90% (e.g., 75% and 50% loads). The motor operates under S1 (continuous) duty, suitable for steady grinding, conveyors, and processing lines in mining settings.
Yes. The motor is flameproof (Exdb), IP66 protection, and insulation class ICLF, specifically designed for hazardous zones in mining. Its Ex-protection and robust enclosure enable safe, continuous operation on conveyors and hoists where dust, moisture, and gases are present.
The motor carries Exdb explosion protection and an IP66 enclosure, along with flameproof construction. It supports IEC-based standards for mining and industrial equipment, with insulation suitable for 40 °C ambient temperatures and 1000 m altitude, ensuring compliance for use in controlled hazardous-area installations.
Higher IE3 efficiency lowers energy costs over the motor’s life, while the robust cast-iron frame and sealed enclosure reduce maintenance needs and downtime. With 8 poles and IMB5 mounting, installation and alignment are straightforward, accelerating deployment and improving overall uptime in mining operations.
