Research on Simulation of Permanent Magnet Speed Governer Based on Ansoft

在分析温度对永磁体性能影响的基础上,提出一种改进的有限元计算转矩方法,并利用Ansoft软件对永磁调速器的数学模型进行电磁场仿真计算,结果表明:改进后永磁调速器的输出转矩与实测值的误差更小。

Based on analyzing permanent magnet’ s temperature influence on its performance,an improved fi-nite element method was proposed to calculate the magnet torque.Simulating the electromagnetic field of the magnet’ s mathematical model with Ansoft and comparing the result with the measured result show that the er-ror between improved torque value and measured value is smaller.
