直驱永磁风力发电机转子 Direct Drive Permanent Magnet Wind Turbine Rotor

技术领域technical field

本实用新型涉及一种直驱永磁风力发电机转子。The utility model relates to a direct-drive permanent magnet wind power generator rotor.

背景技术Background technique

大功率直驱式风力发电机通常采用瓦片形钕铁硼磁极,瓦片形磁极安装在永磁发电机转子体上,其磁化方向通常为径向方式。在先技术中,对于瓦片形钕铁硼磁极固定在转子的转体上,采用的方法是将钕铁硼磁极的底面做成异形槽,在转体上加工出与钕铁硼磁极相对应的异形槽,其槽形通常为燕尾形,在槽内加注粘接剂将钕铁硼磁极粘结固定在转体上;也有在钕铁硼磁极的中心位置加工一通孔,用螺栓紧固并加粘接剂粘结的方法将钕铁硼磁极固定在转体上。采用上述方法要在转体上加工出多条异形槽,加工难度较大,同时,在钕铁硼磁极装配过程其表面保护层容易受到损伤,可能导致磁极表面保护镀层碎裂;此外要将磁极做成与轴线成一定夹角的斜极也是非常困难。High-power direct-drive wind turbines usually use tile-shaped NdFeB magnetic poles. The tile-shaped magnetic poles are installed on the rotor body of the permanent magnet generator, and the magnetization direction is usually radial. In the prior art, for the tile-shaped NdFeB magnetic poles are fixed on the rotating body of the rotor, the method adopted is to make the bottom surface of the NdFeB magnetic poles into special-shaped grooves, and process the corresponding NdFeB magnetic poles on the rotating body. The special-shaped groove, the groove shape is usually dovetail shape, and the adhesive is filled in the groove to bond and fix the NdFeB magnetic pole on the rotor; there is also a through hole processed in the center of the NdFeB magnetic pole, and fastened with bolts The NdFeB magnetic pole is fixed on the rotating body by adding an adhesive bonding method. Using the above method to process a plurality of special-shaped grooves on the rotor, the processing is difficult. At the same time, the surface protective layer is easily damaged during the assembly process of the NdFeB magnetic pole, which may cause the protective coating on the surface of the magnetic pole to be broken; It is also very difficult to make an oblique pole that forms a certain angle with the axis.
