Abstract

Nowadays, developing electric motorization for land vehicles is essential due to the crucial need to save energy. Regarding the specific speed-torque characteristics (high saturation level, high speed, considerable flux weakening) and manufacturing cost, the Interior Permanent Magnet (IPM) Synchronous Machine (SM) provides considerable advantages. This paper presents the development of a tool used for optimal acoustic and electromechanical modeling of an IPM-SM, whose highly accurate calculations and speed of resolution make it stand out from standard analytical and Finite Element models. By coupling an analytical model with static Finite Element Analysis (FEA), our `hybrid' model calculates a complex global air-gap permeance per area unit, to take into account magnetic wedge permeability, stator slots shape, pre-slot height, permanent magnets (PMs) dimensions, and rotor yoke shape. An unparalleled level of precision and time of resolution are obtained for the computation of air-gap magnetic pressures.

改进的内置永磁同步电机气隙磁压计算方法

目前，由于节能的迫切需要，发展陆地车辆电动化是必不可少的。在特定的速度-转矩特性(高饱和水平、高速度、磁链明显减弱)和制造成本方面，内置永磁(IPM)同步电机(SM)具有相当大的优势。本文介绍了一种用于IPM-SM最佳声学和机电建模的工具的开发，其高度精确的计算和分辨率速度使其从标准的解析和有限元模型中脱颖而出。通过将解析模型与静态有限元分析(FEA)相结合，我们的“混合”模型计算出每个面积单位的复杂全局气隙磁导率，同时考虑到磁楔磁导率、定子槽形状、预槽高度、永磁体(pm)尺寸和转子轭形。计算气隙磁压力的精度和分辨率都达到了前所未有的水平。
