A method for discharging energy stored in a stator of an assisted steering electric motor of a motor vehicle is disclosed. The stator includes at least one electrical phase, where a state of disconnection of said phase with a control device of the stator is controlled by a switch device having at least one field effect transistor. The method involves keeping the field effect transistor in linear mode by controlling the voltage Vgs between the gate and the source of said transistor so as to keep the voltage Vds between the drain and the source of said transistor substantially equal to a reference voltage Vref.
