FIELD: electricity.
SUBSTANCE: three-phase two-phase rotating transformer (10) comprises a three-phase (11) and two-phase (12) sections that are movable in rotation relative to each other about axis A. The three-phase section (11) comprises a first ferromagnetic material body and three-phase coils (24, 25, 26, 27). The two-phase section (12) comprises a second body of ferromagnetic material and two-phase coils (28, 29, 30, 31). In the second housing, a first annular groove (34) with axis A and a second annular groove (35) with axis A are formed. The two-phase coils comprise a first toroidal coil (29) with axis A in first groove (34), a second toroidal coil (28) with The axis A in the first slot (34), the third toroidal coil (30) with the axis A in the second slot (35) and the fourth toroidal coil (31) with the axis A in the second slot (35). The first (29) and fourth (31) coils, as well as the second (28) and third (30) coils are connected in series.
EFFECT: reduction of residual magnetism and current release when switching on.
