Abstract
A rotary electrical machine comprises a rotor including a plurality of poles and a plurality of windings (E0-E7) wound about the poles, a stator, and a compensation device configured to compensate the armature magnetic reaction of the stator. The compensation device comprises at least one permanent compensation magnet which is implanted in a pole(s) of the rotor. The magnet(s) is/are sized and placed in accord with the desired compensation effect desired.
