ABSTRACT:
An autosynchronous motor comprises a control and power circuit for the windings of a stator generating a rotating field the angular direction of which is a function of the magnetizing direction of the permanent magnet of the rotor, and to a positioning device producing a signal representing the angular position of the rotor relative to the stator windings. This positioning device emits one pulse per rotation; it comprises a moveable member integral with the rotor and a steady or fixed member integral with the stator.
The stator member of the positioning device and the stator comprise complementary means so that this stator member can, by manual operation, be rotated around the axis of the motor. Marking references are provided for predetermined angular positions of the stator member. These complementary means are, for example, on the stator constituted by a ball repelled by a spring and on the stator member by a number of notches equal to the number of pairs of the rotor.
