摘　　要：本文在大电机定子空心导体分层的基础上 ,推导了导体交流电阻的数值计算公式。论文以交流电阻为目标函数 ,空心部分的矩形宽度为变量 ,在考虑约束的情况下 ,用直接法中的黄金分割法编程寻优并确定了对应最小交流电阻时空心部分的尺寸。On the basis of stator hollow conductor layer building in large electric machines,the paper deduces numerical formula for calculating conductor alternating current resistance.It selects alternating current resistance as target function,width of hollow area as variable for optimization.When restrained conditions are considered,it uses gold cutting method,one of the direct search methods,to develop program and determines dimensions of conductor hollow area,which are referred to minimum alternating current resistance.The satisfactory calculated results are also given in the paper.
