The paper presents a method for identifying the parameters of a new model of induction motor. This model has two rotor loops in order to take into account the deep-bar effect and a non-linear leakage reactance which represents magnetic saturation effect. These phenomena cannot be neglected when induction motor dynamic characteristics have to be evaluated. The test method is simple and non-iterative. Only two locked-rotor tests at rated current and different frequency are required to derive the parameters of the two rotor loops. A further locked-rotor test at a suitable current value is necessary to determine the non-linear leakage reactance of the model

Abstract
The paper presents a method for identifying the parameters of a new model of induction motor. This model has two rotor loops in order to take into account the deep-bar effect and a non-linear leakage reactance which represents magnetic saturation effect. These phenomena cannot be neglected when induction motor dynamic characteristics have to be evaluated. The test method is simple and non-iterative. Only two locked-rotor tests at rated current and different frequency are required to derive the parameters of the two rotor loops. A further locked-rotor test at a suitable current value is necessary to determine the non-linear leakage reactance of the modelI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
