Tubes à rayons X Résumé : In recent research, a field reconstruction (FR) technique was developed to enable more efficient evaluation of the magnetic fields and forces within induction machines. By using the FR, the results of two finite-element (FE) solutions (in which stator current is used as the input to the FE model) are used to establish basis functions for the flux densities in the air gap of the machine. The basis functions are then used to predict the magnetic fields and forces under arbitrary stator excitation. In this paper, the technique is enhanced to enable modeling with stator voltage (rather than stator current) as the model input. This enables a more convenient coupling of the FR model to external circuit components to model overall system performance.
