Abstract

This article presents the design and comprehensive multiphysics analysis of a permanent magnet synchronous motor (PMSM) intended for small electric podded propulsion systems in marine applications. Minimizing vibration related to underwater radiated noise (URN) and ensuring thermal stability to allow prolonged continuous operation are crucial aspects of propulsion motor design. To reduce URN, particular attention is given to the stator vibration mode order, determined by the slot/pole combination (SPC) of the PMSM. Structure-borne noise analysis is used to evaluate the equivalent radiated power level of three designed PMSMs with different stator vibration mode orders. One-way multiphysics analysis using finite element analysis (FEA) is performed in a water environment for the finally-selected PMSM with pod housing structure. URN generated from the electromagnetic force is predicted by structural-acoustics analysis. Through lumped-parameter thermal network (LPTN) and computational fluid dynamics (CFD) analyses, it is proposed that, based on the cylindrical housing shape, the thermal stability of the podded propulsor can be evaluated using LPTN analysis instead of CFD analysis. A prototype motor is fabricated to validate the results obtained using FEA.

用于船用吊舱推进的永磁同步电机的设计与综合多物理场分析

本文介绍了一种永磁同步电机（PMSM）的设计和综合多物理场分析，该电机用于海洋应用中的小型电动吊舱推进系统。最大限度地减少与水下辐射噪声（URN）相关的振动，并确保热稳定性以实现长时间连续运行，是推进电机设计的关键方面。为降低水下辐射噪声，需要特别关注定子振动模式顺序，该顺序由 PMSM 的槽/极组合 (SPC) 决定。结构噪声分析用于评估三种具有不同定子振动模式阶次的 PMSM 的等效辐射功率水平。利用有限元分析 (FEA) 在水环境中对最终选定的带吊舱外壳结构的 PMSM 进行了单向多物理场分析。通过结构声学分析预测了电磁力产生的 URN。通过叠加参数热网络（LPTN）和计算流体动力学（CFD）分析，提出基于圆柱形外壳形状，可以使用 LPTN 分析而不是 CFD 分析来评估吊舱式推进器的热稳定性。为验证使用有限元分析获得的结果，制作了一个原型电机。
