Abstract: A switching device for an electric motor including at least one fixed portion equipped with a number of connecting elements that can be joined to the terminals of each phase, at least one first moveable portion that can be moved with respect to the fixed portion between at least one first position in which the phases are in a first electrical configuration and at least one second position, in which it is disconnected from the phases, at least one second moveable portion that can be moved with respect to the fixed portion between at least one first position in which the phases are in a second electrical configuration, separate from the first, and at least one second position, wherein it is disconnected from the phases, and a movement unit linked to the first and to the second moveable portions and which can be selectively switched, depending on the operating conditions of said electric motor, between at least a first configuration, in which the first moveable portion is placed in the first position and the second moveable portion is in the second position, and a second configuration, in which the first moveable portion is placed in the second position and the second moveable portion is in the first position.

Abstract: A switching device for an electric motor comprises a fixed body, at least one moveable body that can be moved with respect to the fixed body between at least one first and one second position, in which the phases (104, 105, 016) are respectively in a first and a second electrical configuration, and a moving unit configured to move said moveable body between the first and the second position. This moving unit can be selectively coupled to the rotor of the electric motor so as to rotate with it and comprises a selecting device operationally placed between the rotor and the moveable body of the switching device and configured to transform each revolution of the rotor into a movement of the moveable body between the first and the second position.
