Abstract

A rotor (3, 4) for an aircraft (1) is described having: a support (9) angularly fixed with respect to an axis (B, C) and housing a power source (20); a unit (11, 12) rotatable about axis (B, C) and housing an electrical load (21, 24) of the resistive type; and a power supply system (19, 19', 19'', 19''', 19"", 19''''', 19""", 19"""') for the electrical load (21, 24) and comprising: a first transformer (22) electrically interposed between the power source (20) and the load (21, 24); the first transformer (22) comprises: a first winding (26) arranged on the support (9) and a second winding (28) arranged on the unit (11, 12, 13), a stator (9) carried by the support (9), rotationally fixed with respect to axis (B, C) and to which the first winding (26) is fixed; and a rotor (101) operatively connected to the unit (11, 12) and to which the second winding (28) is fixed; the power supply system (19, 19', 19", 19'", 19"", 19'"", 19""", 19"""') comprises a capacitive circuit (50) electrically connected to the first transformer (22), so as to reduce the reactive power absorbed by the rotary transformer (22).
