摘　　要：针对目前大型永磁直驱风力发电机定子安装机座设计笨重的缺陷,提出一种新型的抗定子变形的结构方案,该方案通过结合发电机组固定部分自身的结构及装配特点,并在特定部位来设置抗变形部件,在解决现有风力发电机定子机座体积庞大、结构笨重等问题的同时,显著提高定子机座的抗拉强度,并有效防止机座在各类发电场合下产生变形。For the problem of large volumes in the stator frame of direct-drive permanent-magnet wind generators, a new deform-resistance structure of the stator was proposed in this paper. Based on the stator itself structure and the assembly characteristics, the structure proposed in this paper solved the problems of large volumes and heave masses for the stator frame, and increased the tensile strength of the stator frame dramatically, and prevented the frame deflection in the conditions of different electric power generations.
