面向AUV的永磁同步推进电机设计与优化

Design and Optimization of AUV Oriented Permanent Magnet Synchronous Propulsion Motor

为了适应水下航行器推进电机在特殊工作环境和性能要求方面的需要,采用“场路结合”的电磁设计方法来设计内置式永磁同步推进电机(IPMSPM)的结构参数,并通过电磁计算软件确定了电机的电磁设计方案。然而,IPMSPM存在转矩脉动大、永磁体耗用量大、效率偏低等不足。针对这些问题,采用了“田口法”开展IPMSPM多目标优化设计研究,并根据多目标迭代优化结果调整初始设计值以确定设计的优化方案。最终,通过电磁场有限元仿真软件ANSYS-Maxwell建立了IPMSPM有限元模型,仿真实验表明,设计的IPMSPM在空载和负载工况下均满足设计要求,并且设计方案合理可行。

According to the special working environment and performance requirements of underwater vehicle(AUV)propulsion motor,the structural parameters of permanent magnet motor are designed by using the electromagnetic design method of"field circuit combination",and the electromagnetic design scheme of motor is determined by using electromagnetic calculation software.Aiming at the shortcomings of large torque ripple,large consumption of permanent magnet and efficiency to be improved,the multi-objective optimization design of permanent magnet synchronous motor is carried out by using Taguchi method.The initial design value is adjusted according to the multi-objective iterative optimization results,and the optimization scheme of the design is determined.Finally,the finite element model of the motor is established with the help of the electromagnetic field finite element simulation software ANSYS Maxwell.The finite element simulation experiment shows that the comprehensive performance of the designed AUV oriented permanent magnet synchronous propulsion motor under no-load and load conditions meets the design requirements and the design is reasonable.
