Abstract

In this paper is used Finite Element Method-FEM for analysis of electromagnetic quantities of small micro motor - single phase shaded pole motor-SPSPM. FEM is widely used numerical method for solving nonlinear partial differential equations with variable coefficients. For that purpose motor model is developed with exact geometry and material's characteristics. Two different approaches are applied in FEM analysis of electromagnetic phenomena inside the motor: magneto-static where all electromagnetic quantities are analysed in exact moment of time meaning frequency f=0 Hz and time-harmonic magnetic approach where the magnetic field inside the machine is time varying, meaning frequency f=50 Hz. Obtained results are presented and compared with available analytical results
应用有限元法对阴极电机电磁现象进行数值分析的不同方法
本文采用有限元法对小型微型电动机-单相阴极电动机- spspm的电磁量进行了分析。有限元法是求解变系数非线性偏微分方程的一种广泛应用的数值方法。为此,开发了具有精确几何形状和材料特性的电机模型。在电机内部电磁现象的有限元分析中应用了两种不同的方法:静磁法,在精确的时间时刻分析所有电磁量,即频率f=0 Hz;时谐磁法,其中机器内部的磁场是时变的,即频率f=50 Hz。给出了所得结果,并与已有的分析结果进行了比较
