A separately excited electric machine having a stator provided with at least one exciter unit and a rotor provided with strips. Each exciter unit comprises two secondary magnetic circuits and one primary magnetic circuit. Each secondary magnetic circuit comprises a stator exciter winding and two annular yokes provided with teeth. The primary magnetic circuit comprises a rotor exciter winding and an annular ring. First magnetic fluxes generated by the primary magnetic circuit circulate around loops in each strip and second magnetic fluxes generated by the secondary magnetic circuits circulate around loops in the strips, the teeth, and the ring. Each strip thus has a first north pole and a first south pole, with the teeth comprising in alternation second north poles and second south poles.

A homopolar motor phase (d) which consists of a wafer (a), the leg (a) of each tooth meeting the leg of the next tooth before touching the cylinder head (a), the leg (a) at least partially filling the space (a) between the teeth. The inner diameter (a) is reduced by the presence of a discontinuity in the area (a) at the tip of the tooth (a).
