摘　　要：为研究套筒式永磁调速器零部件温升特性对其传动性能的影响,本文运用磁热双向耦合的方法对套筒式永磁调速器在运行时的温度场进行数值仿真分析,并在此基础上分析了永磁体温升退磁效应对永磁调速器传动性能的影响,最后搭建试验平台进行实验验证。分析结果表明,当N48SH永磁体温度由20℃上升至140℃时,永磁调速器的输出转矩下降了29.09%,解释了永磁调速器的温升特性与系统传动性能之间的联系,为套筒式永磁调速器的优化设计和性能预测奠定了基础。In order to examine the influence of the thermal characteristics of the cylinder-permanent magnet governor(CPMG)on transmission performance,an electromagnetic-thermal bi-directional coupling simulation of CPMG is carried out.The temperature distribution of CPMG and the demagnetization effect due to the temperature rising is discussed through numerical simulation in ANSYS,and validated in experimental tests.Results show that,when the temperature of CPMG increases from 20 to 140℃,the output torque is reduced by 29.09%,which provides a basis for the design and prediction of optimal performance of CPMG.
