Performance Analysis of Single Phase Short Circuit of Three Phase Induction Motor Based on the Method of Field and Circuit

Abstract

According to the short circuit fault occurs in single-phase winding of three-phase induction motor， based on the basic theory of electrical machinery，adopting the research method of combining field and circuit， taking an 11 kW cage type three-phase induction motor as an example，a field circuit coupled analysis model and constraint conditions of motor stator winding single-phase short circuit is given，the internal magnetic field analysis and calculation of the motor，and the motor magnetic saturation effect on the reactance value，get a more accurate current and torque curve.
