Research on the radial electromagnetic force of an inverter-fed induction machine on different switching frequency using FEM

Radial electromagnetic force generated in the stator core is the main source of electromagnetic noise and vibration. In this paper, a 2-D field-circuit coupling analysis by time-stepping finite element method (FEM) is conducted to get the radial electromagnetic forces of inverter-fed induction machine.This method loads the stator winding voltage of inverter-fed condition. It mainly focuses on the effect to the radial electromagnetic force of an inverter-fed induction machine in different switching frequency´s´ conditions.
