FAQs
The motor is designed for a 400 V, 50 Hz three-phase supply with a D (Delta) connection configuration, which aligns with common industrial drives and switchgear. With a 75 kW output on a 2-pole frame, it integrates smoothly with standard VFDs, starters, and belt-conveyor systems, reducing wiring complexity and commissioning time.
In mining environments the motor delivers IE3 efficiency at full load (75 kW), with robust protection (IP66) and Exdb flameproof certification. The IE Class data at 50 Hz shows Full Load efficiency around 94.7%, supporting energy savings. Rated for up to 1000 m altitude and 40 °C ambient, it maintains consistent torque for conveyors and pumps with minimal derating.
Yes. It features Exdb flameproof protection and IP66 enclosure, certified for explosive environments. The IMB3/IM1001 mounting compatibility and rugged cast-iron frame further support safe installations in mining and other hazardous areas, with reliable cooling and protection under continuous operation.
The motor’s specifications include Exdb flameproof protection, IP66 enclosure, and ICFL insulation. It supports IMB3/IM1001 termination classes and is designed for high-temperature resilience in demanding environments. These certifications help ensure regulatory compliance and safer operation in mining and other hazardous-zone applications.
Energy savings from IE3 efficiency combined with longer service life from a robust 6316/C3 bearing arrangement and ICFL insulation lower operating costs and maintenance frequency.
