Title: The application of finite element method for determining the THD in the electromotive force in a synchronous machine with permanent magnets rnder different loads
Keywords: Finite Element Method (FEM), Synchronous Permanent Magnet Motors, (SPMM), Total harmonic distortion (THD)
Abstract: In the report there is an algorithm given for determining the Total Harmonic Distortion (THD) in the electromotive force under different loads. Object of the study is a synchronous machines with excitement from permanent magnets imbedded in the rotor (SPMM), widely used in hybrid vehicles. There are two cases of stator windings studied – the first case is a three phase, ten pole machine with q = 2 (q - number of slots per pole and phase) and the second case is with two independent three phase, ten pole windings with q = 1. The study was made by modeling of the magnetic field with the “FEMM” software, and with additional program modules that calculate the THD in the software environment MatLab and Excel. As the obtained data is analyzed the value of the THD is compared to the previously determined standard values from previous studies and researches.
