Abstract :
This paper describes a d-q-axis model of synchronous permanent magnet machines at high frequency. Both the inductive and resistive saliencies are taken into account and the model results particularly suitable to investigate the self-sensing capability of the machines. It is proved that the high frequency machine response can be described by means of three complex parameters which form a symmetrical matrix. It is also shown that the high frequency resistances between the d- and q-axis exists, and they may assume a negative value.
