Abstract in different language: This paper deals with design influence of SRM on its torque ripple. The construction, size and width of stator and rotor poles are changed. The size and construction of stator and rotor yokes and air gap are without changes. On the base of good coincidence between measurements and simulations by means of Finite Element Method (FEM), all construction designs are simulated and calculated by means of FEM under program FEMM. The parametric model of SRM has been created for quick design changes of mentioned parameters. The static parameters of SRM have been calculated by means of FEM and also its torque ripple. The combination of various construction changes, the design with lower torque ripple has been obtained than in real SRM.
Tento článok sa zaoberá vplyvom konštrukčnej úpravy SRM na zmenu zvlnenia momentu. Konštrukčne sa menia šírka pólu statora, rotora a zmena ich tvarov. Veľkosť jarma statora, rotora a vzduchovej medzery ostávajú nezmenené. Na základe dobrej zhody merania a simulácie v metóde konečných prvkov, sú všetky konštrukčné úpravy a ich vplyv na zvlnenie momentu SRM urobené prostredníctvom MKP v programe FEMM. Bol vytvorený parametrický model na rýchlu zmenu jednotlivých konštrukcií. Pomocou FEMM boli vypočítané statické parametre motora a aj zvlnenie momentu. Kombináciou jednotlivých úprav sa získalo nižšie zvlnenie momentu ako v reálnom stroji.
