Saturation influence of the induction motor magnetic system on the current spectrum powered by a pulsed voltage source
Main Article Content
Abstract
A model for the study of the fundamental and higher stator current harmonics with a certain magnetic system saturation of the induction motor from form of power supply was proposed. The influence of induction motor magnetization curve non-linearity of the stator current form, powered by the three-phase bridge inverter was analyzed. The method of accounting non-linearity of the magnetization curve in the stator current spectrum analysis was proposed. A result of current spectra for different states of the induction motor was shows.
