Abstract
A rotary electric machine including a flux-concentrating rotor with permanent magnets disposed between pole pieces, and a stator with teeth having a free end deprived of pole swellings and a concentrated winding. The pole pieces and the magnets are configured so as to minimize the difference Ld−Lq where Ld is inductance on a forward axis and Lq is inductance on a quadrature axis.
