Boasting over 70 years of experience in manufacturing large and medium high-voltage AC motors, our products cover a power range of 0.55KW to 20000KW and voltages from 380V to 13.8KV, with the 2000KW high voltage motor as our flagship product. Widely deployed in petroleum, chemical, coal, power station, metallurgy and grain processing sectors, these motors drive fans, pumps, compressors, crushers and all kinds of heavy conveying machinery. We adopt field-circuit coupling electromagnetic design and FEM structural analysis to optimize component loss, wind resistance and mechanical strength, delivering strong overload capacity, low vibration and low noise while cutting ventilation loss to boost overall efficiency. We select premium raw materials including cast iron/steel frames, pure copper stators, copper/aluminum rotors, ASTM1045 steel shafts and SKF/FAG-grade bearings. A strict full-process QC system is implemented: all measuring instruments are calibrated annually, with detailed inspections for coils, iron cores, rotors, shafts and complete assembly. Every finished motor undergoes mandatory routine tests, while high-power units receive sampling type tests covering temperature rise, overload endurance and efficiency verification. Motors feature a standard 120μm anti-corrosion paint layer with customizable colors. Seaworthy plywood or fumigated wooden packaging is adopted for overseas transportation. Our standard warranty covers 12 months after commissioning or 18 months after delivery, whichever comes first, and extended warranty plans are available upon inquiry. With stable quality, flexible customization and full technical support, we serve global industrial customers with reliable heavy-duty drive solutions.
