1. An aircraft turbomachine, comprising:
a gas generator having a longitudinal axis,
a fan located at an upstream end of the gas generator and configured to rotate about said axis, and
an electric machine having an annular shape mounted coaxially downstream of the fan, and which comprises a rotor rotatably coupled to the fan, and a stator,
the fan configured to generate a main gas flow, a portion of which flows into a primary annular duct of the gas generator to form a primary flow, and another portion of which flows around the gas generator to form a secondary flow,
the primary duct being delimited by first and second annular envelopes coaxial with the gas generator, the primary duct being passed through by bladings, referred to as IGV, configured to connect the first and second envelopes, as well as by tubular arms of an inlet casing located downstream of the IGV arms,
the gas generator comprising a third annular envelope which coaxially surrounds the second envelope, the second and third envelopes being connected together at their upstream ends to form an annular splitter nose that separates the primary and secondary flows,
wherein the stator of the electric machine is connected to a power electronic circuit by at least one rigid electroconductive bar, the bar comprising a first portion extending radially with respect to said axis inside one of the IGV arms, and a second portion extending parallel to said axis between the second and third envelopes.
