Accurate prediction of magnetic field and magnetic forces in permanent magnet motors using an analytical solution / Liu, Z. J. in IEEE transactions on energy conversion, Vol. 23 n°3 (Septembre 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°3 (Septembre 2008) . - pp. 717 - 726 Titre : Accurate prediction of magnetic field and magnetic forces in permanent magnet motors using an analytical solution Type de document : texte imprimé Auteurs : Liu, Z. J., Auteur ; Li, J. T., Auteur Année de publication : 2008 Article en page(s) : pp. 717 - 726 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Brushless  machines;  finite  element  analysis;  machine  theory;  magnetic  coresmagnetic  fields;  magnetic  forces;  optimisation;  permanent  magnet  motors Résumé : This paper presents an analytical model suitable for analyzing permanent magnet motors with slotted stator core. By including the effect of the interaction between the pole transitions and slot openings, the model is able to predict the airgap field and magnetic forces with high accuracy, which cannot be achieved using the previously available analytical methods. The results of electromagnetic forces, i.e., the cogging torque and unbalanced magnetic pull, computed analytically agree well with numerical simulations using the finite-element method. The model is used to analyze the magnetic forces developed in permanent magnet brushless motors when the design parameters vary in wide ranges. The model is useful in design and optimization of permanent magnet motors.
