Abstract: An electric or hybrid electric-endothermic traction system comprises an electric machine (2), an inverter (5), a battery pack (Batt), and a switching device (4) associated with the electric machine (2) and configured to switch it between a low-speed configuration, in which the stator windings (3) assume a first electric configuration, and a high-speed configuration, in which the stator windings (3) assume a second electric configuration, wherein the first electric configuration of the stator windings (3) results in a voltage induced by the rotation of the rotor (BEMF1 ) that, on reaching a pre-determined threshold value (ω_th) of the angular velocity of the rotor (2b), exceeds a supply voltage of the battery pack (V_batt), whereas the second electric configuration of the stator windings (3) results in a voltage induced by the rotation of the rotor (BEMF2) that is lower than the voltage of the battery pack (V_batt) for any angular velocity within a range of use of the electric machine (2). An emergency device (7) is connected to the switching device (4), control unit (6) and/or inverter (5) and is configured to send to the switching device (4) a signal (S2) representing a switching of the stator (2a) from the low-speed configuration to the high-speed configuration, if said stator is in the low-speed configuration, or a disabling of the switching device (4), if said stator is in the high-speed configuration.

Abstract: An electric or hybrid electric-endothermic traction system, comprises an electric machine (2), an inverter (5), a battery pack (Batt), and a switching device (4) connected to the electric machine (2) and configured to switch it between a low-speed configuration, wherein the stator windings (3) assume a first electric configuration, and a high-speed configuration, wherein the stator windings (3) assume a second electric configuration, wherein the first electric configuration of the stator windings (3) determines a voltage induced by the rotation of the rotor (BEMF1 ) that, on reaching a pre-determined threshold value (ω_th) of the angular velocity of the rotor (2b), exceeds a supply voltage of the battery pack (V_batt), while the second electric configuration of the stator windings (3) determines a voltage induced by the rotation of the rotor (BEMF2) that is lower than the voltage of the battery pack (V_batt) for any angular velocity within a field of use of the electric machine (2). The switching device (4) is configured to impart to the stator (2a) a switching from the low-speed configuration to the high-speed configuration when the rotor (2b) reaches a switching speed that is lower than or equal to the threshold value (ω_th).

Abstract: A switching device for an electric motor (100) provided with a plurality of phases (104, 105, 106) comprises a fixed body (2) equipped with a plurality of connection portions (3) and at least one moveable body (5, 10) that can be moved with respect to the fixed body (2) between at least a first position, in which the phases (104, 105, 106) are arranged in a first electrical configuration, and a second position, in which the phases (104, 105, 106) 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 (107, 108) within each phase (104, 105) and/or due to the reciprocal connection between the phases (104, 105, 106).

Abstract: An electric motor comprises a plurality of phases and a switching device (106). 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 (105). The switching device (106) is coupled to the first group (104) and is operable to switch an electrical configuration thereof. The second group (105) of phases is instead configured to maintain its electrical configuration unchanged during the switching of the electrical configuration of the first group (104).
