Product Description

Product Description
4. Xmw Air-to-Air Cooled Doubly-Fed Wind Turbines
        The motor is matched to 4.X MW platform doubly-fed wind turbine, with excellent low noise and high efficiency. The rotor shaft at the drive end is connected to the medium-speed gearbox through a coupling to drive the generator. The stator is directly connected to the power grid, and the rotor is connected to the power grid through a four-quadrant converter, which can supply power within +/-38% of the synchronous speed and regulate the power factor of the power grid. The innovative air-to-air cooling design eliminates the need for an air-to-water cooling system for the unit, which helps to boost the market share of 'feed-in tariffs'.

Main technical features

        1.Patented technology for self-ventilating structure, small wind resistance inside the motor, large air volume, which can solve the temperature rise problem caused by the contradiction between large loss of high-power motor and lack of air-air cooling, large temperature rise margin of the motor, and long service life;
        2.The stator and rotor coils adopt moulding winding; the rotor adopts corona-resistant mica insulation structure of polyimide film, which can withstand a certain pulse voltage of the frequency converter; H-class insulation structure, vacuum pressure dipping paint, high reliability;
        3.Adoption of insulated end cover structure and grounded brush design can greatly reduce the damage of axial voltage and axial current to the bearings; Split slip ring chamber structure can isolate the pollution of carbon powder to the motor and enhance the reliability;
        4.The slip ring chamber adopts independent fan for ventilation and cooling, and the special structure is conducive to carbon powder discharge, which improves the reliability of motor operation;
        5.Passed the certification of Weighing and Balancing
