Description
Die Erfinc^ng betrifft einen polarisierten Mikromotor für Uhren mit mindestens einer Rahmenspule, die mit mindestens einem magnetischen Kreis zusammenwirkt, der ein Paar von Pe -nanentmagneten aufweist, deren Magnetisierungsachsen rechtwinklig zur Spulenachse stehen und die in unmittelbarer Nähe der Spule angebracht sind, wobei die Felder der Magnete parallel, jedoch einander entgegengesetzt gerichtet stehen.The invention relates to a polarized micromotor for clocks with at least one frame coil that interacts with at least one magnetic circuit, which has a pair of Pe -nanentmagneten, the magnetization axes of which are perpendicular to the Stand coil axis and which are attached in the immediate vicinity of the coil, with the fields of the magnets parallel but opposite to each other.
Bei einem bekannten Antriebssystem dieser Art (deutsche Auslegeschrift 1157 158) sind einteilige Permanentmagnete verhältnismäßig umständlicher Form vorgesehen, die auf eine kreisringförmige Spule wirken. Die Spule überdeckt sich mit den Magneten auf einer beschränkten Fläche, woraus sich ein entsprechend beschränkter magnetischer Fluß ergibt. Der auftretende Streufluß ist hoch, wodurch das nutzbare Feld zusätzlich <jeschwächt wird.In a known drive system of this type (German Auslegeschrift 1157 158) are one-piece Permanent magnets of a relatively cumbersome shape are provided on an annular coil works. The coil covers itself with the magnets on a limited area, from which a accordingly limited magnetic flux results. The leakage flux that occurs is high, which means that the usable field is also weakened.
Es ist bei einem bekannten Starkstromgcncrator auch vorgeschlagen worden, einteilige, U-förmige Kerne von Elektromagneten beidseitig einer Rahmenspule anzuordnen. Abgesehen davon, daß die einteilige Herstellung des Joches und das Aufbringen der Wicklungen schwierig ist, treten infolge der verhältnismäßig langen Schenkel des U-förmigen Jochs erhöhte Streuverluste auf. In einer für eine Kleinuhr bestimmten Anordnung ist jedoch auf optimale Ausnutzung des verfügbaren magnetischen Flusses zu achten.It is with a known high voltage generator It has also been proposed to use one-piece, U-shaped cores of electromagnets on both sides of a frame coil to arrange. Apart from the fact that the one-piece production of the yoke and the application of the windings is difficult to occur due to the relatively long legs of the U-shaped yoke increased wastage. In an arrangement intended for a small watch, however, optimum use is made of it Pay attention to the available magnetic flux.
Der Erfindung liegt die Aufgabe zugrunde, ein in der Herstellung einfaches und eine optimale Nutzung der vorhandenen Permanentmagnete erlaubendes Magnetsystem in einem Mikromotor für Uhren m schaffen. Der crfindungsgema'ße Mikromotor ist dadurch gekennzeichnet, daß parallelepipedförmige Magnete vorgesehen sind, auf deren zur Spulenachse parallelen Polflächen Polschuhe zur Leitung des Magnetfeldes durch die Ralimenspule angebracht sind, ohne über die Polflächen vorzustehen.The invention is based on the object of creating a magnet system in a micromotor for watches m which is simple to manufacture and which allows optimal use of the permanent magnets present. The micromotor according to the invention is characterized in that parallelepiped-shaped magnets are provided, on whose pole faces parallel to the coil axis pole shoes are attached for conducting the magnetic field through the rail coil without protruding over the pole faces.
Die Magnete können in diesem Falle in Richtung der Spulenachse dick ausgeführt werden, weil ihr Feld auch aus von den der Spule entfernten äußeren Teilen durch die Pjlschuhe der Spule zugeführt wird, während der Streufluß sehr gering ist. Es ist damit möglich, ein intensiveres Feld aufzubauen als bei bekannten Mikromotoren vergleichbarer Abmessungen. Die mehrteilige Ausführung der Magnetsysteme aus Permanentmagneten einfachster Form bnd Polschnhen ebenfalls einfacher Form erlaubt eine billige rationelle Fertigung.The magnets can be made thick in this case in the direction of the coil axis, because you Field is also supplied from the outer parts remote from the coil through the pads of the coil, while the leakage flux is very low. It is thus possible to build up a more intensive field than with known ones Micromotors of comparable dimensions. The multi-part design of the magnet systems Permanent magnets of the simplest form bnd pole pieces also simple form allows a cheap, efficient production.

In Fi g. 1 ist ein Teil eines Halters mit zwei Schenkeln 1 α und I b dargestellt, weiche Schenkel eine gewisse Elastizität aufweisen. In diesen Schenkeln sind die Enden einer flachen Torsionslamelle 2 eingespannt. In ihrer Mitte ist als Schwingmasse ein steifer Stab 3 befestigt. An den Enden des Stabes 3 sind einerseits eine Rahmenspule 4 und andererseits ein nicht dargestelltes Gegengewicht befestigt, derart, daß das System bezüglich der Achse der Torsionslamelle statisch ausgewuchtet ist.In Fi g. 1 shows a part of a holder with two legs 1 α and 1 b , soft legs have a certain elasticity. The ends of a flat torsion lamella 2 are clamped in these legs. A stiff rod 3 is attached as an oscillating mass in its center. At the ends of the rod 3 on the one hand a frame coil 4 and on the other hand a counterweight (not shown) are attached in such a way that the system is statically balanced with respect to the axis of the torsion lamella.
Die Spule 4 ist mit einem magnetischen Kreis gekoppelt, der ein Paar von Magneten 5 und 6 sowie zwei Paare von Polschuhen 7,8 und 9, 10 aufweist. Die Spule win) von einem stabilen Oszillator, beispielsweise einet« Quarzoszillator gespeist.The coil 4 is coupled to a magnetic circuit which has a pair of magnets 5 and 6 and two pairs of pole pieces 7, 8 and 9, 10. The coil is fed by a stable oscillator, for example a quartz oscillator.

Die Polschuhc 7, 8 und 9, 10, die zur Leitung des magnetischen Fiusses durch die Spulenseiten dienen, sind auf den Polflächen der Magnete 5 und 6 angebracht und bedecken dieselben ohne darüber hinaus vorzustehen. Die Polschuhe 7 bis 10 sind Prismen von nahezu dreieckigem Querschnitt, deren Seite größerer Dicke der Spule zugewandt ist, womit der Streufluß optimal beschränkt werden kann.The pole shoes 7, 8 and 9, 10, which are used to conduct the magnetic flux through the coil sides, are attached to the pole faces of the magnets 5 and 6 and cover the same without beyond to preside. The pole pieces 7 to 10 are prisms with an almost triangular cross-section, the side of which the coil is facing greater thickness, so that the leakage flux can be optimally limited.
Beim dargestellten Ausführungsbeispiel ist die am Stab 3 befestigte Spule 3 beweglich, während der magnetische Kreis fest angeordnet ist. Die Anordnung könnte aber auch umgekehrt, d. h. mit feststehender Spule und beweglichem magnetischem Kreis getroffen werden.In the illustrated embodiment, the attached to the rod 3 coil 3 is movable, while the magnetic Circle is firmly arranged. However, the arrangement could also be reversed, i. H. with fixed Coil and moving magnetic circuit.
