摘要:

提出一种新型混合式永磁调速器,具有轴向和径向磁路结构,可提高整机输出转矩密度。给出混合式永磁调速器物理结构和结构参数,建立混合式永磁调速器的温度场求解数学模型,完成传热特性和损耗分析。采用有限元法完成混合式永磁调速器温度场仿真分析,最高温度位于轴向铜盘,最高温度达到107 ℃。对比有无散热筋对混合式永磁调速器机壳的散热作用,发现有散热筋比无散热筋机壳温度降低25.4%。搭建混合式永磁调速器温度场测试实验平台,获得混合式永磁调速器不同部件的温度分布。与仿真值相比,实验数据数值基本一致。

Abstract:

A new-type hybrid adjustable permanent magnetic coupler which has a magnetic structure both in axial and radial direction was present to improve the complete machine output torque density. The physical structure and structure parameters were provided, then the temperature solving mathematical model of hybrid adjustable permanent magnetic coupler was established and the heat-transfer characteristic and loss analysis were finished. The finite element method (FEM) was adopted to calculate the temperature field of hybrid adjustable permanent magnetic coupler, where the highest temperature was located at axial copper plate, reaching to 107 ℃. Compared heat dissipation with bucket rib to without bucket rib for hybrid adjustable permanent magnetic coupler, the conclusion was that temperature of the former was scaled down 25.4% than the latter one. The temperature filed test experiment system of hybrid adjustable permanent magnetic coupler was built and temperature distributions in different part of hybrid adjustable permanent magnetic coupler were obtained. Compared with simulation data, the data is consistent.
