- a MOT stepper motor is housed in the control member which consists of two shells COQ1 and COQ2 nestable one inside the other.
- the shells are made of an alloy aluminum treated by anodic oxidation.
- the stepper motor is connected to processing means (not shown) by FI connection wires.
- the stepper motor includes a rotor (not shown) whose rotation shaft corresponds to the axis of rotation AX of the control member.
- Motor not MOT step consists of a parallelepiped-shaped carcass, secured to the axis of rotation AX using a ring U-shaped BAG that completely encloses the housing containing the stepper motor.
- Bearing and circlip means ROU1 and ROU2 complete the means of guiding in rotation free of the stepper motor.
- the stepper motor is hybrid type, that is to say that the ROT rotor is permanent magnet on the one hand, and the torque rotor / stator has a structure capable of introducing a change in reluctance on the other hand.
- the stepper motor is the one sold by the MINEBEA company (Japanese company) under the reference 14 PM-M201-T2 six-wire ( Figure 6) or four-wire ( Figure 5).

- the 4-wire stepper motor includes a ROT rotor on the circumference of which are arranged teeth of alternately different polarities DR and magnetized by a permanent magnet included in the rotor.
- the STA stator includes at least first to fourth poles magnetic PM1 to PM4 arranged around the rotor and having each of the DS teeth.
- a first BA coil is wound in the same direction around first and third opposite poles PM1 and PM3.
- a second coil BB is wound in the same direction around second and fourth opposite poles PM2 and PM4.
- a terminal EA1 of the coil BA is connected to ground and the other terminal EA2 of the coil BA is connected to an amplifier shaping device followed by a CT1 peak detector suitable for delivering synchronous TR1 logic pulses with the analog signal present at terminal EA2.
- a terminal EB1 of the coil BB is connected to ground and the other terminal EB2 of the coil BB is connected to an amplifier shaping followed by a CT2 peak detector suitable for delivering synchronous TR2 logic pulses with the analog signal present at terminal EB2.
- shaping and detection circuits CT1 and CT2 is to make the generation of pulses TR1 and TR2 logic independent of the rotation speed of the rotor while maintaining the synchronism of the pulses relative to the engine pitch.
- Processing means UT are connected to circuits CT1 and CT2 to process the two trains of pulses TR1 and TR2 and deduce the direction of rotation of the control member, its angular displacement, and therefore its rotation speed.
- the processing means UT are thus able to select the display of a parameter using the electrical quantities supplied by the step-by-step engine.
- the motor pitch is thus proportional to this difference.
- the step of the stepper motor is 1.8 °.
- this engine step by step can also give a tactile effect to the organ control.
- the UT processing means are able to activate said first and second coils BA and BB for braking or inductively block the rotation of the control member by depending on the parameter displayed on the display means or in response to a predetermined condition.
- the means of UT processing deliver through a CT3 control circuit a DC signal, from 0 to 12 Volts for example, at terminals EA2 and EB2 of the coils BA and BB.
- the braking control circuit CT3 is with high internal impedance IM1 and IM2 so as not to influence reading the pulses on the coils BA and BB.
- the stepping motor described with reference to FIG. 5 is of bipolar type insofar as the coils BA and BB are crossed by currents in both directions.
- the stepping motor is of the type unipolar in which the coils are traversed by currents in one direction.
- the unipolar stepper motor is here 6-wire. Its rotor ROT is identical to that described with reference to Figure 5. Its stator is different from that described with reference to the Figure 5 insofar as further coils BA and BB arranged identically to FIG. 5, it comprises now a third BC coil strongly coupled with the first BA coil and wound in the same direction as the first BA coil around the first and third poles magnetic PM1 and PM3 and a fourth BD coil strongly coupled with the second BB coil and wound in the same sense that the second BB coil around the second and fourth PM2 and PM4 magnetic poles.
- the coils BA and BB are no longer activated by the means of treatment.
- the control circuit CT3 (without high internal impedance) now activates the third and fourth coils BC and BD to inductively brake or block the rotation of the ORG control member according to the parameter displayed on the display means or in response to a predetermined condition.
- the means of UT processing deliver through the control circuit CT3 a DC signal, from 0 to 12 Volts for example, at terminals EC1 and ED1 of the coils BC and BD.
- EC2 and ED2 of the coils BC and BD are grounded.
- the user feels on the ORG control unit a tactile effect which can be depending on the change of the item displayed and selected.
- the braking effect can be constant, or depending on certain circumstances such that the selected rubric, or the absence of action of the user for a predetermined time delay, or again the instantaneous speed printed on the control unit by the user.
- microcomputer means of treatment managing the screen which will control the intensity of the braking as well as its duration by determining the control signal from the circuit CT3.
