Abstract
The invention mainly relates to a rotating electrical machine (10) comprising: a rotor (12) provided with a rotor winding (13); a stator (11) provided with a winding (14) having a plurality of phases; a converter (16) comprising rectifying components (17) to which the phases of the stator (11) are connected; a voltage regulator (24) for adapting an excitation current (lexc) applied to the rotor winding (13) according to a difference between an output voltage (Liait) and a reference voltage; at least one current sensor (27) arranged at the output of the rotating electrical machine (10) or on at least one phase of the rotating electrical machine (10); and a diagnostic module (30) that can detect a malfunction of the rotating electrical machine (10) on the basis of a current measurement provided by the current sensor (27).
