Abstract
This paper deals with the parameter identification of induction machine rotor and stator windings. These two magnetically coupled circuits are described and analyzed to explain the novel method that can identify the set of substitute parameters (not equivalent circuit parameters) which can be used for some analysis of transient processes in a stationary induction machine. The parameters are: inductive leakage factor, substitute rotor resistance, substitute rotor inductance, and substitute mutual inductance. The method belongs to the group of so-called off-line methods, i.e., it is performed on a machine in a standstill, and it assumes a star-connected induction motor. The correctness of the method is verified by calculation as well as by measurement. Moreover, the practical use of the method is shown in an example of how to determine the rotor winding temperature rise, and the results of the measurement on an induction motor with a power of 0.75 kW are presented. The method can be performed even when the rotor circuit is hidden inside the completely closed rotor construction, as in the case of a squirrel cage induction motor, i.e., without access to the rotor circuit.
