An Identification Method of Equivalent Circuit Constants in the Capacitor-start Single-phase Induction Motor

Abstract

In this paper, the authors describe a method to identify equivalent circuit constants of the main and auxiliary windings.
According to this method, the DC decay testing method is applied to the main or auxiliary winding of capacitor-start single-phase induction motor, and the operational impedance are calculated for each winding. From the operational impedance thus calculated, we use the relation between the main winding and auxiliary winding converted to main winding based on electric energy conservation law to calculate the equivalent. circuit constants.
The usefulness of this method is proven by comparing the measurements and the values calculated from identified equivalent constants.
