Calculation of d- and q-axis inductances of PM brushless ac machines accounting for Skew [PDF]
, 2005 A hybrid two-dimensional (2-D) finite-element/analytical technique is described for predicting the d-axis and q-axis inductances of permanent magnet (PM) brushless ac machines, with due account for the influence of skew.

Methods of resistance estimation in permanent magnet synchronous motors for real-time thermal management [PDF]
, 2010 Real-time thermal management of electrical ma- chines relies on sufficiently accurate indicators of internal tem- perature. One indicator of temperature in a permanent-magnet synchronous motor (PMSM) is the stator winding resistance.

Influence of the amount of permanent-magnet material in fractional-slot permanent-magnet synchronous machines [PDF]
, 2014 The efficiency of permanent-magnet (PM) synchronous machines with outer rotor and concentrated windings is investigated as a function of the mass of magnets used, keeping the power, volume, and mechanical air-gap thickness constant. In order to be useful
