Standstill Self-Commissioning of an Induction Motor Drive

This paper deals with the parameter identification of an induction motor at standstill. A comprehensive identification procedure is analyzed, describing a robust flux-integration method for main-flux saturation characteristics and transient tests for rotor-side parameters. The influence of the main-flux saturation on the transient test results and on the identified rotor-side parameters is studied, and improvements are suggested. The identification procedure is validated by means of experiments using 2.2-kW and 5.6-kW induction motors.
