Abstract
Starter system for an electric motor (M) supplied by an electrical network (), the starter system comprising an electronic control circuit () and an electronic switch () for controlling one phase of the motor (M), the electronic switch () being controlled by the control circuit (). The starter system comprises a sensor () intended to deliver an analog signal () that is representative of the derivative of a current flowing through the phase of the motor (M), a detection board () comprising means for transforming said analog signal () into a binary signal () that is representative of the changes in sign of said analog signal, and comprising means for transmitting said binary signal to the control circuit (), so as to optimize the control of the electronic switch ().
