A braking actuator for an aircraft brake, the actuator comprising a casing integrating: an electric motor comprising a stationary portion and a movable portion that is movable relative to the stationary portion; the stationary portion carrying an exciter member adapted to drive the movement of the movable portion when the exciter member is electrically powered; • a pusher that is movable in translation relative to the casing along a pusher travel axis; • mechanical means for transforming travel movement of the movable portion of the motor into movement in translation of the pusher; and • a position sensor for sensing the position of the movable portion relative to the stationary portion; the position sensor comprising a transmitter member and a receiver member, the transmitter member being adapted, when powered electrically, to excite said receiver member at least when the movable portion is moving relative to the stationary portion, the receiver member being adapted to generate at least one signal (S1, S2) representative of the position of the movable portion when said receiver member is excited by said transmitter member; the exciter member of the motor comprises at least first and second exciters (17a, 17b), each exciter being adapted, when powered, to drive the movement of the movable portion relative to the stationary portion, these exciters (17a, 17b) being arranged to be capable of being powered electrically independently from each other; and the transmitter member of the position sensor comprises at least first and second transmitters (20a, 20b), each transmitter (20a, 20b) being adapted, on being powered, to cause at least one signal (S1, S2) representative of the position of the movable portion to be sent by the receiver, the transmitters (20a, 20b) being arranged to be capable of being electrically powered independently of each other; the actuator being characterized in that it further comprises an integrated inverter inside the casing of the actuator and adapted to power said first exciter, this integrated inverter being connected to first terminals of the actuator so as to be capable of being powered by a power source external to the actuator; and - the second exciter is wired to second terminals of the actuator so as to be capable of being powered by an external inverter external to the actuator. an electric motor comprising a stationary portion and a movable portion that is movable relative to the stationary portion; the stationary portion carrying an exciter member adapted to drive the movement of the movable portion when the exciter member is electrically powered; • a pusher that is movable in translation relative to the casing along a pusher travel axis; • mechanical means for transforming travel movement of the movable portion of the motor into movement in translation of the pusher; and • a position sensor for sensing the position of the movable portion relative to the stationary portion; the position sensor comprising a transmitter member and a receiver member, the transmitter member being adapted, when powered electrically, to excite said receiver member at least when the movable portion is moving relative to the stationary portion, the receiver member being adapted to generate at least one signal (S1, S2) representative of the position of the movable portion when said receiver member is excited by said transmitter member; • a pusher that is movable in translation relative to the casing along a pusher travel axis; • mechanical means for transforming travel movement of the movable portion of the motor into movement in translation of the pusher; and • a position sensor for sensing the position of the movable portion relative to the stationary portion; the position sensor comprising a transmitter member and a receiver member, the transmitter member being adapted, when powered electrically, to excite said receiver member at least when the movable portion is moving relative to the stationary portion, the receiver member being adapted to generate at least one signal (S1, S2) representative of the position of the movable portion when said receiver member is excited by said transmitter member; the exciter member of the motor comprises at least first and second exciters (17a, 17b), each exciter being adapted, when powered, to drive the movement of the movable portion relative to the stationary portion, these exciters (17a, 17b) being arranged to be capable of being powered electrically independently from each other; and
