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 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.

Abstract: Method for reconfiguring an electric machine including a rotor arranged to rotate with an angular speed (ω), the electric machine being arranged to pass from a first configuration (config1) to a second configuration (config2), the method comprising the steps of: a) determining in real-time a real speed threshold (ωreal_th) depending on the current operating condition of the electric machine; b) checking if the angular speed (ω) of the rotor is greater than said real speed threshold (ωreal_th); c) in positive case, no reconfiguration is performed from the first configuration (config1); d) in negative case: d.1) determining the current configuration of the electric machine; d.2) selecting a reconfiguring decision method; d.3) deciding whether to reconfigure the electric machine or not and, in positive case, reconfiguring the electric machine.
