A starter assembly (1) for a heat engine, including: a drive shaft (7) including an annular groove (53); a bushing (15) mounted so as to be translatably movable relative to the drive shaft (7); a pinion (17) mounted on the bushing (15); an element (25) for stopping the bushing (15), which is mounted in the annular groove (53) of the drive shaft (7), the stopping element (25) being a resilient circular part which is radially expandable and which consists of an at least 360 metal winding, the inner diameter of which falls between the diameter of the annular groove (53) and the diameter of the drive shaft (7). The dimensions of the stopping element (25) can also be such that the stopping element is rotationally connected to the drive shaft.


The invention relates to a control loop (10) which is installed in a voltage regulator of a motor vehicle alternator and controls an output voltage of the latter by adjusting an excitation current of the alternator. The control loop includes, at the input, means for measuring (31) the output voltage by sampling, generating a measurement signal (Um), error-calculation means (13) generating an error signal (e) equal to a difference between the measurement signal (Um) and a set value (Uo), means for processing the error signal (e) including an amplifier (14) and generating a control signal (Ysat) and, at the output, means (35) for generating a control signal (PWM) controlling excitation control means in accordance with the control signal (Ysat). According to the invention, the processing means also include a phase-advance filter (24).
