    Abstract: 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, in which the stator windings assume a first electric configuration, and a high-speed configuration, in which the stator windings assume a second electric configuration, wherein the first electric configuration results in 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, whereas the second electric configuration of the stator windings results in a voltage induced by the rotation of the rotor that is lower than the voltage of the battery for any angular velocity within a range of use of the machine. An emergency device is connected to the switching device, control unit and/or inverter.
