The present invention relates to a device of the current indexing mater type.
continuous brush direction, whose angular position of the shaft is linked to the else state
stick of the stateric windings. There is only a single position of the ar
bre for a given electrical configuration of the stators.
L'asservissement d'une position angulaire d'un arbre moteur est traditionnelle ment réalisée soit par un moteur P courant continu ou courant alternatif, associé
à un organe xtérisur s potentionètre, codeur, synchro machins, soit par un moteur
pas à pas essecié à un organe de comptage du nombre de pas effectués, la position
de l'arbre étant inconnue au départ, sens précaution spéciale pour la déterminer.The control of an angular position of a motor shaft is traditionally carried out either by a direct current or alternating current motor P
to an organ xterisur s potentioneter, encoder, synchro things, either by a motor
step by step with a counting device for the number of steps taken, the position
of the tree being unknown at the outset, sense special care to determine it.
Le dispositif selon l'invention lie anguleirement sur 360 , d'une manière quasi
rigide, l'arbre moteur, 1 l'état électrique du stator qu'elles qu'ainent été les
rotations passées.The device according to the invention links angularly over 360, in an almost
rigid, the motor shaft, 1 the electric state of the stator that they were
past rotations.
Il comporte en effet s un stator principal compèsé d'un certain nombre de paires
de polas portant des bobinen d'induction. Chaque paise de poles étant isolés ma
gnétiquement de la précédente et de la suivante dans le description suivante :
- un stator ennexe comportent autant de peires de pôles
que le stator principal. L'exe du stator annexe étant excentré par rapport à l'axe
du stator principal, ce dernier étant matérielisé par l'axe moteur0 Le stator annexe
est lié à l'erbre moteur comportant un excentrique par un roulement à bille ou a u
tre.It indeed has a main stator with a number of pairs
of polas carrying induction coils. Each pole lodge being isolated my
genetically from the previous and the next in the following description:
- an annexed stator have as many pole peers
than the main stator. The exe of the annex stator being offset from the axis
of the main stator, the latter being materialized by the motor axis 0 The annex stator
is linked to the motor shaft with an eccentric by a ball bearing or to the
be.
Lo mouvement décrit par chacun des pôles du stator annexe est un mouvement de
va et vient dont l'amplitude est l'impage de la différence entre le royon maximal
et le rayon minimal de l'axcontrique par rapport au centre de l'axe moteur. The movement described by each of the poles of the annex stator is a movement of
back and forth whose amplitude is the image of the difference between the maximum royon
and the minimum radius of the axcontric with respect to the center of the motor axis.
Le champ megnétique se referme ainsi longitudinalement,chaque paire de pôles
du stator principal agissant sur la p.ire de pôles, en vie à vie du stator annexe,
à la manière d'un électro simant.The megnetic field thus closes longitudinally, each pair of poles
of the main stator acting on the pole pole, lifetime of the annex stator,
like an electro simulator.
Salon uns forme de réalisation préférentielle, l'axe moteur est pourvu ds 2
excontriques placés di mgniero identique par rapport 9 l'exe et séparée par une
distance correcte pour supporter, su moyen de roulements à billes ou autre, le
stator unnexe.Living room as a preferred embodiment, the motor axis is provided with 2
eccentrics placed di mgniero identical to 9 exe and separated by a
correct distance to support, by means of ball bearings or other, the
annex stator.
Salon une variente, un seul excentrique et un seul roulement pourraient suffire. Living room a variety, a single eccentric and a single rotation could be enough.
L'alimentation des bobinsges d'un pôle voisin du pôle préslablement aexcité, crée
un déplacement du stator annexe, et cs mouvement par l'excentrique crée une rotation
de l'arbre.The supply of the coils of a pole close to the pre-excited pole creates
a displacement of the annex stator, and this movement by the eccentric creates a rotation
of the tree.
Les deux etstors peuvent être constitués de matériaux magnétiques, sans rémencecs ou non. Un simant plein ou tubulaire pout être placé dnes le aens de l'axe à llimtérieur du stator annexe. Dans cette dernière condition, le moteur cours un couple au repos an dehors de toute alimentation du stator principal. De plus, lore de l'elimentation du stator principal, toue lee pôles hore de la position angulaire choisis pourront être alimentée de façom teils qu'il a créont un champ répusif, une souls peire de pôles étent elimentés pour créer un champ attractif. The two etstors can be made of magnetic materials, without remembers or not. A solid or tubular simant can be placed in the middle of the axis inside the annex stator. In this latter condition, the motor runs a torque at rest without any power from the main stator. In addition, the power of the main stator, all the poles hore of the angular position chosen can be powered in ways that it has created a repulsive field, a souls of poles are powered to create an attractive field.
Pour équilibrer dynamiquement le moteur, bien que la atator annexe ne soit pas tournant, mais cocillant, il est possible pour les moteurs de puissance élevée, de les construlre sur un axe portent 2 paires d'excentriques et de réaliser ainsi um mcteur double dont les stators annexes, avec leur propoes excentrique,s seraient de
Dans le cas où un mimant ast inclue dans le ou les stators annexes, le ou les stators principaux pouvant être réalisés de la manière conventionnelle des moteare à champ tournant. Dans cette concaption, les pôles de atator annexe peuvent être divisés à la manière du retor de moteur pas à pas.To dynamically balance the engine, although the annex atator is not rotating, but coquette, it is possible for high power engines, to build them on an axis carry 2 pairs of eccentrics and thus to realize a double mcteur whose additional stators, with their eccentric props, would be
In the case where a mimic ast is included in the annexed stator (s), the main stator (s) can be produced in the conventional manner of rotary field moteares. In this design, the auxiliary atator poles can be divided in the same way as the stepper motor retor.
