Starting device for an internal combustion engine, especially that of a motor vehicle, comprising:

• a stator (3), or inductor, comprising an inductor coil (5), said inductor coil comprising a plurality of windings (40-43), especially all electrically connected in parallel;
• a rotor associated with said stator and having a longitudinal axis;
• a starter element that can be rotated by the rotor;
• and
• a contractor (17) designed to supply power, in a prerotation first phase, only to some of the windings of the inductor coil and, in a full-speed second phase, following the first phase, to all of the windings of the inductor coil;
• said contractor (17) has a longitudinal axis (X) and comprises first and second electrical contact elements (58, 59) designed to supply power to the electric motor, enabling the latter to operate in succession in a prerotation first phase and a full-speed second phase, each of the first and second contact elements (58, 59) being able to move along the longitudinal axis between an open state and a closed state, the number of windings activated in the second phase being equal to or greater than twice the number of windings activated in the first phase.
