摘　　要：依据指标优化设计一款额定功率为7.5kW、效率大于89.7%的永磁同步曳引机。由于磁路法单一参数扫描无法分析永磁曳引机中多变量、强耦合关系,以及设置斜槽或斜极时存在削弱齿槽转矩同时牺牲一定的输出转矩这一对不可调和的矛盾,现通过自适应性响应面法(ARSM)对曳引机各参数优化调整,同时引入新变量单元斜率以此中和永磁曳引机固有矛盾,计算出最佳斜槽角与最佳设计点,然后有限元仿真曳引机各项优化特性并试制样机。结果表明,引入单元斜率后基于ARSM优化可使曳引机齿槽转矩峰峰值缩小88.3%而效率提升一个百分点,且试制样机具有宽广高效的运行范围。According to the index,a permanent magnet synchronous traction machine with a rated power of 7.5kW and an efficiency greater than 89.7%was designed.Due to the single parameter scan of the magnetic circuit method,the multi-variable and strong coupling relationship in the permanent magnet traction machine cannot be analyzed.And there is an irreconcilable contradiction about weakening cogging torque and sacrificing a certain output torque when setting the oblique slot or oblique pole,so parameters of the traction machine were optimized and adjusted by Adaptive Response Surface Method(ARSM),and a new variable‘cell slope’was introduced to neutralize the inherent contradiction of the permanent magnet traction machine.While this paper calculated the optimal chute angle and optimal design point,and simulated optimization characteristics of the traction machine through finite element and then made a prototype.The results show that the ARSM-based optimization can reduce the peak-to-peak value of the cogging torque of the traction machine by 88.3%and increase the efficiency by one percentage point after introducing the cell slope,and the trial-produced prototype has a wide and efficient operating range.
