摘要
目前,永磁同步电机的功率密度、转矩密度正在快速提升,电机系统单位体积下的损耗和发热功率也在快速升高。这给电机系统的散热、温度场建模和热管理带来很大挑战。目前国内外文献关于电机温度场建模和热管理方面的文献数量众多,方法种类繁杂,缺乏系统的分析和归纳。针对这一问题,本文对近年来国内外电机温度场分析、建模和热管理的方法进行了梳理和分析,以期能够较为系统地呈现电机温度建模与热管理的发展现状和发展趋势。
Currently,the power density and torque density of permanent magnet synchronous motors are rapidly increasing,leading to a significant rise in losses and heat generation per unit volume in motor systems.This presents significant challenges for heat dissipation,temperature field modeling,and thermal management in motor systems.While there is a wealth of literature both domestically and internationally on the modeling of motor temperature fields and thermal management,the methods are diverse and lack systematic analysis and synthesis.To address this issue,the methods in recent domestic and international literature related to the analysis,modeling,and thermal management of motor temperature fields are reviewed and analyzed.The aim is to present the current state and trends in the development of motor temperature modeling and thermal management in a more systematic manner.
