ABSTRACT:
The stepping motor (1) is provided with magneto-mechanical means (11) in order to reverse the rotation sense of its rotor (2). When the magnetic element (12) is withdrawn or flush with the gap (3), the rotor turns in the sense of the arrow (27). When such element is extended into the gap through application of pressure to the push-piece (14), the rotor will turn in the sense opposite to that of the arrow (27).
