A rotary electrical machine comprises a rotor including a plurality of poles and a plurality of windings (E-E) 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.

Rotary electric machine with armature magnetic reaction compensation

A machine () having a rotor () including permanent magnets (PM) and field coils (EC). The magnets are housed in first axial recesses (E) distributed within a circumferential portion of the magnetic body, thus defining circumferential polar sections. The coils are housed in second axial recesses (E) distributed within an intermediate portion of the magnetic body and defining pole teeth (RT). The ratio of a width of a pole tooth to a height of a permanent magnet is around 0.65 to around 1.

Synchronous rotary electric machine having a hybrid-excitation rotor

A machine () having a rotor () including permanent magnets (PM) and field coils (EC). The magnets are housed in first axial recesses (E) distributed within a circumferential portion of the magnetic body, thus defining circumferential polar sections. The coils are housed in second axial recesses (E) distributed within an intermediate portion of the magnetic body. The circumferential polar section includes a third recess (E), and a portion of the magnetic body forming a bridge having a height of around 0.7 mm to around 2 mm is retained between an apex of the recess and an outer pole face.

A machine () having a rotor () including permanent magnets (PM) and field coils (EC). The magnets are housed in first axial recesses (E) distributed in a circumferential portion of the magnetic body, thus defining circumferential polar sections. The coils are housed in second axial recesses (E) distributed in an intermediate portion of the magnetic body and defining polar teeth (RT). The circumferential polar section includes a third recess (E) having a maximum width at the top thereof, and the ratio of the maximum width of the third recess to a pole width of the circumferential polar section has a value of around 0.13 mm to around 0.44 mm.
