Inductance Calculations of Permanent-Magnet Synchronous Machines Including Flux Change and Self- and Cross-Saturations
TL;DR: In this article, the total flux in the d and q axes are obtained from finite element method or measurements and therefore include saturation and cross-couplings, and the inductance values are the ones seen by the converter or grid, as found by a more accurate approach.
Research on the Cooling System of a 4QT Prototype Machine Used for HEV
TL;DR: In this paper, the authors investigated the cooling system of a four-quadrant transducer (4QT) and calculated the thermal field with finite element method (FEM).

TL;DR: In this paper, the authors evaluate different concentrated fractional pitch winding designs in comparison to a distributed full pitch winding design with one slot per pole per phase as a reference, and the results of the machine performance comparisons are based on a comprehensive use of finite element analysis tools.

Determination of d and q reactances of permanent-magnet synchronous motors without measurements of the rotor position
TL;DR: In this paper, a method is presented where the induced EMF and the d-axis reactance are determined in a no-load test and the q-axis reactionance is determined by means of a load test.
