ex d motor

Ex d Motor Manufacturer and Supplier

Shaanxi Qihe Xicheng Electromechanical Equipment Co., Ltd. specializes in providing enterprise-grade ex d motor solutions for hazardous industrial environments. Our flagship YBK3 series flameproof three-phase aSynchronous Motors deliver power ranging from 0.75 to 315 kW, with voltage configurations including 380V, 660V, and 1140V. These motors achieve IE3 high-efficiency standards while maintaining explosion-proof certification Ex d I Mb for underground coal mine operations. Backed by over 20 years of industry experience and partnerships with 30+ global motor manufacturers, we ensure reliable power delivery in environments containing methane and coal dust.

Pain Points vs. Solutions

Operating motors in explosive atmospheres presents significant challenges. Traditional equipment fails under methane exposure, coal dust accumulation, and extreme underground humidity. Our product systems address these critical issues:

Challenge: Gas ignition risk in underground mines

Solution: Thickened cast iron flameproof housing with reinforced joint surfaces prevents flame propagation.

Challenge: Moisture and coal dust infiltration

Solution: Mine-specific sealed cable entry devices with IP55 protection grade block contaminant intrusion.

Challenge: Premature failure from corrosion

Solution: Enhanced anti-corrosion coating withstands underground damp environments and mine water erosion.

Challenge: Excessive energy consumption

Solution: IE3 efficiency rating reduces power loss by 15-20% compared to legacy YBK2 models during continuous S1 operation.
