Product Description

Product Description

          The motor is a 2.5MW plateau air-air-cooled doubly-fed wind turbine, supporting the 2.5MW variable-speed doubly-fed wind turbine, used in wind farms in the plateau area at an altitude of 3,000m and below.
        The motor is installed in the nacelle and is suitable for variable-speed and constant-frequency wind turbines. The wind turbine drives the rotor of the generator through the main shaft and the gearbox after speed change, and the stator of the generator sends out 690V, 50Hz three-phase alternating current through the transformer, which is directly connected to the power grid and generates electricity on the grid; in the range of +/-38% of synchronous rotational speed, the rotor is connected to the power grid through the frequency inverter to carry out the bidirectional flow of energy and realise the variable-speed and constant-frequency power generation. Constant frequency power generation.
        As a key component of the wind turbine, it mainly includes, welded chassis, core winding assembly, insulated end cover, three-phase wire-wound rotor, slip ring brush holder assembly and slip ring chamber, stator and rotor junction box, sensor and auxiliary junction box device, lightning protection device, encoder and so on.

Main technical features

        1.Adopting proprietary bearing structure and insulation technology to effectively inhibit bearing galvanic corrosion;
        2.The winding adopts vacuum pressure dipping paint and rotary baking technology to enhance the insulation reliability of the motor; H-class insulation technology is adopted to ensure the relatively longer service life of the motor;
        3.The finite element simulation design of electromagnetism and structure makes this motor featured with low noise, low harmonic and low temperature rise, as well as the ability to operate at 3MW in common area;
        4.Combined with the characteristics of the rotor lead of the wire-wound 6-pole motor, the structure is reasonably arranged so that the motor achieves the requirement of high-speed dynamic balance with minimum balancing amount;
        5.The products have passed the classification society certification.
