BEIDE 1MT8004/5 Gas Explosion-Proof IE3/IE4 Low-Voltage Three-Phase Asynchronous Motor

BEIDE’s 1MT8004/5 series is a specialized gas explosion-proof low-voltage three-phase asynchronous motor, engineered to meet IE3 (Class 2 efficiency) and IE4 (Class 1 efficiency) standards, complying with IEC 60034-30 and GB30254-2024. With Ex e增安型 explosion-proof certification, it is tailored for hazardous environments with flammable gases, integrating high energy efficiency, reliable explosion protection, and stable performance for critical industrial applications.

Adopting a robust HT250 cast iron housing, the motor features an enhanced explosion-proof structure that prevents ignition of external flammable gases by internal sparks. It holds IP54 protection rating and adopts IC411 totally enclosed fan-cooled design, effectively isolating dust and moisture while ensuring efficient heat dissipation. The F-class insulation system reinforced by vacuum pressure impregnation (VPI) technology boosts electrical reliability, with low vibration (meeting IEC 34-14 N-class) and noise ≤75dB(A) for quiet operation.

Designed for 380V/400V low-voltage operations at 50Hz, the 1MT8004/5 series covers a power range of 75kW to 1000kW, with pole numbers 2-8 and rated speeds 750-3000 RPM. IE4 models achieve over 95% efficiency, saving 10%-15% energy compared to IE3 versions, aligning with global green manufacturing goals. Equipped with precision-cast aluminum rotors, it delivers 1.15 service factor and 150% overload capacity for 60 seconds, adapting to fluctuating loads.

Widely applied in petrochemical, pharmaceutical, and coal mining industries, it is suitable for Zone 2 hazardous areas with flammable gas environments. Supporting multiple mounting modes (IMB3/IMB5/IMB35) and inverter compatibility, it integrates flexibly into diverse production systems. Backed by BEIDE’s strict quality control and professional after-sales service, this motor provides a safe, durable solution for hazardous area operations and energy-saving upgrades.
