Tubes à rayons X Résumé : This paper describes a design methodology to achieve optimal performance for a short-stroke single-phase tubular permanent-magnet motor which drives a reciprocating vapor compressor. The steady-state characteristic of the direct-drive linear-motor compressor system is analyzed, an analytical formula for predicting iron loss is presented, and a motor-design procedure which takes into account the effect of compressor loads under nominal operating condition is formulated. It is shown that the motor efficiency can be optimized with respect to two leading dimensional ratios. Experimental results validate the proposed design methodology.

Enhanced optimal torque control of fault-tolerant PM machine under flux-weakening operation / Sun, Zhigang in IEEE transactions on industrial electronics, Vol. 57 N° 1 (Janvier 2010)  

Public ISBD [article]  inIEEE transactions on industrial electronics > Vol. 57 N° 1 (Janvier 2010) . - pp. 344 - 353 Titre : Enhanced optimal torque control of fault-tolerant PM machine under flux-weakening operation Type de document : texte imprimé Auteurs : Sun, Zhigang, Auteur ; Wang, Jiabin, Auteur ; Jewell, Geraint W., Auteur Article en page(s) : pp. 344 - 353 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Fault tolerant Flux weakening Permanent-magnet (PM) machines Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper describes an enhanced optimal-torque-control strategy for fault-tolerant permanent-magnet (PM) machines under flux-weakening operations. By adjusting the degree of flux weakening according to estimated instantaneous-torque-control errors, the torque-control performance of the machine can be improved when operating above its base speed under either open- or short-circuit fault condition. Extensive simulations under both healthy and fault conditions have been undertaken in order to validate the effectiveness of the proposed control strategy. Experimental results have also been given based on the testing of a prototype five-phase fault-tolerant PM machine.
