| 摘要 |
The machine according to the invention is of the type of those comprising a rotor (2) having alternating north and south poles and excitation coils (3) housed in first recesses (4) which are distributed regularly around a shaft (5) of the rotor. These first recesses are arranged radially in the rotor between a central part and a circumferential part of the rotor and extend axially, in such a way as to define polar sections (6). Each excitation coil is inserted around a core forming a partition between two first consecutive recesses, the core being substantially aligned with a central radial axis (d) of the corresponding polar section. In accordance with the invention, the rotor furthermore comprises a plurality of permanent magnets (7) exhibiting a substantially tangential direction of magnetization, which are arranged in second recesses (8) and extend substantially in radial symmetry planes of the polar sections (6), in such a way as to compensate the armature magnetic feedback. |
