Abstract

The invention relates to a method for energising a coil for driving a moving contactor core of an electric starter for a motor vehicle, in which the effective current is varied in the coil during displacement of the core to its contact position, and in which, in the course of this displacement, there take place:a first driving phase with an effective current which is high enough to set the core in motion, and thena second driving phase with a smaller effective current, in which, after a determined or predetermined time, the effective current is continuously increased.
