Abstract
A rotary three-phase transformer with free linked fluxes including a first portion and a second portion that are movable in rotation relative to each other about an axis A. A first body defines a first annular slot of axis A, a second annular slot of axis A, a third annular slot of axis A, and a fourth annular slot of axis A. The coils of the first portion include a first toroidal coil of axis A in the first slot, a second toroidal coil of axis A in the second slot, a third toroidal coil of axis A in the second slot, a fourth toroidal coil of axis A in the third slot, a fifth toroidal coil of axis A in the third slot, and a sixth toroidal coil of axis A in the fourth slot.
