Switching device for an electric motor and an electric motor comprising said switching device

A switching device for an electric motor, said motor comprising a plurality of phases extending between their respective terminals and each preferably provided with at least one first phase fraction and at least one second phase fraction each extending between two ends, where each terminal corresponds to one end of a first or second phase fraction;

• said switching device being characterised in that it comprises:
• a fixed body equipped with a plurality of connection portions that can be joined to the ends of the first and second phase fraction and/or the terminals of the phases;
• 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;
• a second position, in which the phases are arranged in a second electrical configuration, separate from the first one due to the connection between the first and the second phase fraction within each phase and/or due to the reciprocal connection between the phases;
• a movement unit configured to move said moveable body between the first and the second position according to the operating conditions of said electric motor;
• characterised in that said moveable body comprises a plurality of contact portions each of which can be joined to a corresponding end of said first and second phase fraction or to a respective terminal of the phases and a plurality of conductive paths operationally placed between said contact portions.
