A VI FOR THE AUTOMATIC TEST OF INDUCTION MOTORS

L. Cristaldi, A. Ferrero, M. Lazzaroni

Abstract

The paper proposes a VI-based method for the automatic determination of the mechanical characteristic of induction motors. The signals coming from an inertial start-up transient are acquired and digitally processed, instead of processing the signals from the traditional load Tests. In order to overcome the inaccuracy given by the stator winding resistance variation due to the temperature variations, the stator winding resistance is constantly measured by means of a dedicated circuit and processed together with the other signals. The results of experimental tests are shown and the method accuracy is discussed.
