摘要
为了研究永磁体的温升问题
以高压实心转子永磁同步电动机为例
依据传热学原理
采用三维有限元方法计算了样机转子温度.建立了实心转子三维温度场模型
给出了其假设条件和边界条件
考虑到永磁电机主要关心永磁体的温度
故对比了永磁体两侧未加绝缘层和永磁体两侧加绝缘层两种情况下对电机转子三维温度场的影响
特别是对永磁体温度的影响
得出了在永磁体两侧加绝缘层可有效地降低永磁体温度
从而对永磁体起到保护作用
避免永磁体在高温下产生不可逆的退磁现象
此方法为降低永磁电机永磁体温度提供了理论依据和解决的途径.
Abstract
【英文摘要】 In order to investigate the problem of permanent magnet temperature rising
the high-pressure solid rotor permanent magnet synchronous motor was taken for example and the prototype rotor temperature field was calculated using Finite Element Methods.Based on heat transfer theory
the 3D temperature field model of the rotor was established.Assumptions and boundary values of the motor were given and the temperature of permanent magnet was analyzed mainly.Then
the temperature comparisons of the permanent magnets ...
