| Abstract |
A method to identify the electrical parameters of an inverter-fed induction motor is presented, whichdetermines the saturation characteristic of the mutual inductance and the other parameters separately.Current displacement effects are taken into account. An advantage of this scheme is the insensitivity tovoltage errors of the inverter. To achieve this, the identification of the constant parameters is based onthe fact that the inverter primarily influences only the real part of the impedance. For the identificationof the saturation characteristic, the impedance difference for 2 different but closely spaced frequencies isevaluated for different magnetic operating points. |
