YX2‑KS450‑2L｜1320kW 11kV High‑Voltage Motor with Air‑Water Cooling

Model YX2‑KS450‑2L is a compact‑structure high‑voltage asynchronous motor with 1320kW(1400kW) power and 11kV rated‑voltage, 2‑pole, speed 2984rpm and B3 installation method, equipped with an air‑water cooling system. It features high power density, low vibration, low noise and tightly‑controlled temperature‑rise for longer service‑life. Modular‑structure improves the interchangeability of spare parts and reduces maintenance costs, suitable for blowers, compressors, crushers in steel‑making, power‑generation, mining, petro‑chemical and nuclear‑power fields.

This series of high-voltage asynchronous motors is independently developed by our company for the steel industry. The motor features a box-type steel plate welded structure with excellent rigidity and strength, offering high efficiency, low noise, low vibration, and high reliability. It is specifically designed for driving air-to-water coolers and cooling systems, and is widely used in steel, metallurgy, power, and other industries.

The motor adopts a modular design concept with a compact structure and high power density, delivering powerful performance in a small footprint. Strict temperature rise control and a reliable insulation system ensure long-term stable operation under harsh steel mill conditions — high temperature, heavy dust, and continuous operation.
