This paper presents comprehensive validation tests of a recent qd0-frame core-loss model of three-phase induction machines at different load conditions. The machine is run at different frequencies/speeds and flux levels. These tests reinforce the model at different operating conditions before further model-based analysis and control design. Moreover, to properly use the model, a series of model parameter...
An analytical three-phase induction machine model is proposed, derived, and validated in this paper. This model is capable for arbitrary <bold>qd0</bold>-frame analysis and core loss estimation at both line-fed and inverter-fed situations. Detailed model-based machine copper and core loss estimations are presented. A simulation verification of the model consistency is given under a changing...
In this paper, a comprehensive behavioral efficiency model of an electric motor drive system is proposed. The proposed model includes all possible motor drive losses without ignoring, approximating or assuming any of the inverter or machine losses, which are usually done for other efficiency models, hence the model is comprehensive. The input (DC electrical) and the output (mechanical) power of the...
