An electric motor with two independent output shafts connected to the rotor by coupling means working in one sense of rotation only, e.g. by means of freewheel clutches. The first freewheel works in one sense of rotation while the second freewheel works in the opposite sense. Two operating devices can be powered by the motor, simply by switching the sense of rotation; an example of use is a combined pump-compressor machine. Various embodiments are disclosed, some of them obtainable as a simple and low-cost modification of an existing motor or motor-pump assembly.

The invention claimed is: 1. An electric motor comprising: a stator of the motor; a rotor rotatable inside said stator, with a selectable sense of rotation; a first output shaft and a second output shaft, disposed one opposite to the other and protruding from opposite sides of said motor; connecting means between said rotor and, respectively, said first output shaft and said second output shaft; wherein said connecting means comprise at least a first freewheel clutch engaging in a first sense of rotation only, and at least a second freewheel clutch engaging only a second sense of rotation opposite to said first sense of rotation, and wherein a jacket housing at least a portion of the first and the second output shafts is coupled to said rotor, so that said jacket gives a further, always-on power output. 2. The electric motor as in claim 1, wherein said freewheel clutches are mounted into said jacket together with supporting bearings of said first output shaft and of said second output shaft. 3. The electric motor as in claim 2, wherein said jacket is protruding outside of the rotor and provides room for keeping said freewheels and bearings outside of the rotor. 4. The electric motor as in claim 3, wherein said freewheels are placed in correspondence of existing support bearings. 5. An electric motor comprising: a stator of the motor; a rotor rotatable inside said stator, with a selectable sense of rotation; a first output shaft and a second output shaft, disposed one opposite to the other and protruding from opposite sides of said motor; connecting means between said rotor and, respectively, said first output shaft and said second output shaft; wherein said connecting means comprise at least a first freewheel clutch engaging in a first sense of rotation only, and at least a second freewheel clutch engaging only a second sense of rotation to said first opposite sense of rotation, wherein said connecting means further comprise a third shaft directly associated to said rotor and extending outside said rotor on both sides, wherein a blind hole is provided at each end of said third shaft for realizing the mounting seats for said first and second output shafts and for said freewheel clutches, and wherein a wall of said third shaft defining said hole provides a jacket generating a further, always-on power output. 6. The electric motor as in claim 5, wherein supporting bearings for said first output shaft and for second output shaft are mounted in said holes at the ends of said third shaft. 7. A combined machine, comprising: an electric motor having, a stator of the motor, a rotor rotatable inside said stator, with a selectable sense of rotation, a first output shaft and a second output shaft, disposed one opposite to the other and protruding from opposite sides of said motor, connecting means between said rotor and, respectively, said first output shaft and said second output shaft, wherein said connecting means comprise, at least a first freewheel clutch engaging in a first sense of rotation only, and at least a second freewheel clutch engaging only a second sense of rotation to said first opposite sense of rotation, wherein a jacket housing at least a portion of the first and the second output shafts is coupled to said rotor, so that said jacket gives a further, always-on power output, wherein at least a first operating device is connected to said first output shaft, and wherein a second operating device is connected to said second output shaft, so that said first and second operating devices are powered by said electric motor in a selectable and independent manner.
