Method and system to optimize the current consumed by an electric drive with a synchronous motor. The present invention relates to a method and a system for optimizing the current consumed by an electric drive comprising a rotary synchronous machine controlled by an electronic converter and a control unit that regulates the speed and determines the values of one or more variables of a vector control. By modifying a control variable and following a perturbation and observation strategy, the minimum current operating point is determined based on a measurement of the current consumed by the drive as a whole (monitoring of the minimum current point tracking).
