Abstract
This work first illustrates the basic dependencies of induction machine parameters on flux and current and describes them by simple equations. Differences of the magnetizing currents at single-phase and three-phase excitation are considered. A novel identification technique accurately determines all parameters and their dependencies on saturation from a few easy-to-perform offline measurements. It has been designed for use on traction drives with direct self control during system startup. The method has been automated and is well suited for application in the field. Optimal operating points for quasi-stationary operation are derived from the identified parameter dependencies and compared to practical measurements.<>Keywords
