Abstract: A switching device for an electric motor provided with a plurality of phases includes a fixed body equipped with a plurality of connection portions and at least one moveable body that can be moved with respect to the fixed body between at least a first position, in which the phases are arranged in a first electrical configuration, and a second position, in which the phases are arranged in a second electrical configuration. The second electrical configuration is separate from the first one due to the connection between the phase fractions within each phase and/or due to the reciprocal connection between the phases.

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, 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.

Abstract: An electric motor includes a plurality of phases and a switching device. The phases extend between respective terminals and are divided into a plurality of distinct groups, in particular at least a first group and a second group. The switching device is coupled to the first group and is operable to switch an electrical configuration thereof. The second group of phases is instead configured to maintain its electrical configuration unchanged during the switching of the electrical configuration of the first group.

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.
