Moncada, Roberto H., Auteur ; Tapia, Juan A., Auteur ; Jahns, Thomas M., Auteur |In this paper, a negative-saliency permanent-magnet (PM) synchronous machine analysis is presented. This particular saliency feature is achieved by replacing a portion of the magnet material by a soft iron piece over the rotor pole. In this mann[...]

Lee, Kevin, Auteur ; Jahns, Thomas M., Auteur ; Lipo, Thomas A., Auteur |New observer-based disturbance-estimation and control algorithms are introduced in this paper that compensate source voltage unbalances. The algorithms are also designed to compensate the detrimental impact of delay effects caused by the digital[...]

Seok-Hee Han, Auteur ; Soong, W.L., Auteur ; Jahns, Thomas M., Auteur |Interior permanent magnet (IPM) synchronous machines can experience large harmonic eddy-current losses in the stator teeth under flux-weakening operation, significantly depressing the efficiency of these machines at high operating speeds. This p[...]

Seok-Hee Han, Auteur ; Jahns, Thomas M., Auteur ; Soong, W.L., Auteur |This paper develops analytical principles for torque ripple reduction in interior permanent magnet (IPM) synchronous machines. The significance of slot harmonics and the benefits of stators with odd number of slots per pole pair are highlighted.[...]
