An electric or hybrid electric-endothermic traction system, comprises an electric machine, an inverter, a battery, and a switching device configured to switch between a low-speed configuration, wherein the stator windings assume a first electric configuration, and a high-speed configuration, wherein the stator windings assume a second electric configuration, wherein the first electric configuration determines a voltage induced by the rotation of the rotor that, on reaching a pre-determined threshold value of the angular velocity of the rotor, exceeds a supply voltage of the battery pack, while the second electric configuration of the stator windings determines a voltage induced by the rotation of the rotor that is lower than the voltage of the battery for any angular velocity within a field of use of the machine. The switching device switches from the low-speed to the high-speed configuration when the rotor reaches a switching speed lower than or equal to the threshold value.
