Y500‑2 1600kW High Efficiency Asynchronous Motor for Pump Fan Mill

Y500‑2 is a high‑speed high‑efficiency squirrel‑cage high‑voltage asynchronous motor with frame size 500, rated power 1600kW and 2‑pole configuration, specially optimized for driving pumps, fans and mills. Manufactured in compliance with IEC international standards, this unit runs at synchronous speed 3000rpm for S1 continuous full‑load operation. It delivers stable high‑speed power output for heavy‑duty industrial facilities, widely deployed in power plants, water conservancy, cement, mining and petrochemical industries. The motor can connect directly to 6kV or 10kV high‑voltage grid, eliminating extra transformer equipment and simplifying overall power distribution layout for pump‑fan‑mill process systems.

Core Technical Parameters 

Electromagnetic design is optimized by finite‑element simulation oriented to high‑speed 2‑pole operating characteristics. The stator core is stacked with premium low‑loss silicon‑steel sheets to restrain iron loss, stray loss and magnetic leakage under long‑term high‑speed full‑load running. Stator windings adopt high‑strength corona‑resistant copper magnet wire and undergo full VPI vacuum pressure impregnation treatment. The integrated solid winding structure improves dielectric strength, thermal stability and resistance against electrical aging, which can withstand grid voltage fluctuation and frequent startup impact. For 1600kW high‑speed condition, copper‑bar squirrel‑cage rotor is adopted instead of cast‑aluminum rotor. It possesses outstanding mechanical strength, low rotor loss and reliable anti‑fatigue performance under high‑speed rotation. Every rotor assembly completes strict high‑precision dynamic balance calibration to control vibration and noise within IEC allowable limits, which is critical for 3000rpm high‑speed operation.

This motor adopts welded steel‑plate box‑type frame with high structural rigidity to resist torque shock from fans, pumps and mills. Standard cooling configuration is IC01 open ventilation: external cool air flows into motor interior and hot air is directly discharged outwards, realizing high‑efficiency heat exchange. The IP23 open‑type structure is suitable for clean and well‑ventilated indoor workshops. For sites with dust or humidity, IP44 or IP54 upgraded protection grade can be supplied with modified ventilation structure. For this high‑speed large‑power model, sliding bearings are equipped as standard. PT100 temperature sensors can be embedded in stator windings and bearing housings as optional configuration, transmitting real‑time temperature signals to central control system for remote monitoring and over‑temperature early warning. Space heater is optional to avoid winding condensation during shutdown periods.

As a dedicated drive for pumps, fans and mills, Y500‑2 1600kW motor fits multiple typical working scenarios. In power industry, it drives large‑capacity forced draft fans and circulating water pumps; in water conservancy projects, it serves high‑flow large‑size water pumps; in cement and mining plants, it supports medium‑sized mills and auxiliary blowers. It can adopt direct‑on‑line startup or match high‑voltage soft starter according to grid capacity. Customization services cover high‑altitude adaptation, damp‑tropical anti‑corrosion coating, special terminal box layout and double shaft extension for different project requirements.

Before delivery, each motor carries out comprehensive factory acceptance tests including insulation resistance test, high‑voltage withstand test, no‑load running test, vibration, noise and power‑factor inspection. Featuring high‑speed stable output, high efficiency, robust mechanical performance and convenient maintenance, Y500‑2 1600kW high‑efficiency asynchronous motor is a proven drive solution for pump, fan and mill equipment in heavy‑industry production lines.
