Analysis of Negative-Saliency Permanent-Magnet Machines

open access: yesIEEE Transactions on Industrial Electronics, 2010
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 manner, the d-axis inductance is increased, whereas the q-axis inductance is almost not affected, leading to the ...
