  • Patent number: 7633246
    Abstract: A linear portable actuator including a direct current electric motor (2) rotationally driving a screw with the aid of a reduction element, wherein the motor (2) is controlled by an electronic module (5) comprising means (12) for the acquisition of instantaneous intensity of a supply current for the motor. Further, the electronic module (5) also comprises means (13) for calculating the differential coefficient in relation to supply-current intensity time, which are connected to means (14) for comparing the differential coefficient to a first predetermined value, and a comparing means controlling means (15) for switching off the supply current it the differential coefficient is greater than the first predetermined value.

    Abstract: The linear portable actuator comprises a direct current electric motor rotationally driving a screw with the aid of a reduction element, wherein said engine is controlled by an electronic module comprising means for the acquisition of instantaneous intensity of the supply current for the motor. The invention is characterized in that the electronic module also comprises means for calculating the differential coefficient in relation to supply-current intensity time, which are connected to means for comparing the differential coefficient to a first predetermined value, said comparing means controlling means for switching off the supply current if said differential coefficient is greater than the first predetermined value.
