a device for supplying electrical a.c. power to the motor (100) of a portable electric machine, said motor being provided in series with a phase-controlled semi-conductor (110), comprising : - a measuring means (130, 170), for measuring the variation of the peak value of the current passing through the motor - detecting means (190), cooperating with said measuring means, for acting on the power supply of the motor to switch off said power supply when the rate of increase of said peak value reaches a predetermined threshold corresponding to the maximum kickback torque that may bear the user of the machine, said measuring means delivering to said detecting means (190), for comparison to a predetermined reference value (180), a signal substantially proportionnal to the rate of increase of said peak value of the current passing through the motor, characterized by the fact that said measuring means comprises, connected in series : - rectifier means (150; d5), for rectifying a signal proportionnal to the current passing through the motor, - integrator means (160; r19, c6), for delivering a signal substantially proportionnal to said peak value of the current passing through the motor, - differentiator means (170; r17, c5), for differentiating the signal delivered by said integrator means, said device further comprising : - inhibitor means (300) for preventing interruption of the power supply by said detecting means during a predetermined period following the turning-on of the motor, - softstart means (410-450) for progressively varying the mean value of the voltage across the terminals of the motor, so as not to exceed, at least during the period of operation of said inhibitor means, the maximum kickback torque that may bear the user, said progressive variation in voltage being obtained by the phase-controlled semiconductor (110), connected in series with the motor, and - means (500) for limiting the mean value of the voltage across the terminals of the motor, cooperating with said softstart means, so as to limit, in any event, the torque produced by said motor to a predetermined maximum value (co), and to allow, in case said predetermined maximum value is reached, the obtention of a stability of the torque produced around said maximum value
ce dispositif d'alimentation comprend des moyens de mesure de la variation d'une grandeur électrique d'alimenta­ tion, de préférence la valeur de crête de l'intensité, représen­ tative du couple développé par le moteur, ainsi que des moyens de détection aptes à interrompre l'alimentation électrique du moteur lorsque le taux d'accroissement de la grandeur électrique dépasse un seuil prédéterminé corres­ pondant au couple de réaction maximal supportable par l'utilisateur de la machine. de préférence, les moyens de mesure comprennent, en série : des moyens redresseurs (150) aptes à délivrer un signal sensiblement proportionnel à la valeur de crête de l'intensité ; des moyens intégrateurs (160) ; et des moyens différentiateurs (170).
