BEIDE 1MT0003 Gas Explosion-Proof IE3 Low-Voltage Three-Phase Asynchronous Motor

BEIDE’s 1MT0003 series is a specialized gas explosion-proof low-voltage three-phase asynchronous motor, strictly compliant with IE3 (Class 3 efficiency) standards per IEC 60034-30 and GB30254-2024. It holds Ex db IIB T4 Gb explosion-proof certification in line with GB 3836-2021, tailored for Zone 1/2 hazardous environments with flammable gases, integrating reliable explosion protection, energy-saving performance, and stable operation for critical industrial scenarios.

Constructed with high-strength HT250 cast iron housing, the motor features a dual explosion-proof structure (隔爆+增安) to prevent internal sparks from igniting external flammable mixtures. It adopts IP55 protection rating and 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 enhances 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 1MT0003 series covers a power range of 15kW to 200kW, with pole numbers 2-8 and rated speeds 750-3000 RPM. As an IE3-compliant model, it achieves excellent energy efficiency, reducing operational costs significantly compared to lower-efficiency motors. Equipped with precision-cast aluminum rotors and finely machined stators, it delivers 1.15 service factor and 150% overload capacity for 60 seconds, adapting to fluctuating load conditions.

Widely applied in petrochemical, pharmaceutical, and coal mining industries, it is suitable for IIB-class explosive gas environments with a maximum surface temperature ≤135℃. 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.
