• Polarisierter Mikromotor.• Polarized micromotor.

Die magnetischen Kreise herkömmlicher polarisierter Mikromotoren weisen lange Polschuhe bezogen auf die Länge der Magnete auf. Verwendet man kurze Magnete mit starkem Koerzitivfeld, ,z.B· Platin-Kobaltmagnete, erreichen die Streuverluste infolge des geringen Abstandes zwischen den Polschuhen und ihrer relativ grossen Länge sehr bedeutende Y.erte und das im Luftspalt verfügbare Feld wird entsprechend geschwächt.The magnetic circuits of conventional polarized micromotors have long pole pieces based on the length of the magnets on. If you use short magnets with a strong coercive field, e.g. Platinum-cobalt magnets, reach the scattering losses as a result of the the small distance between the pole pieces and their relatively great length, the Y.erte and that available in the air gap Field is weakened accordingly.

Die vorliegende Erfindung bezweckt eine Verbesserung dieser Verhältnisse in einem polarisierten Mikromotor. Dieser Mikromotor, der mindestens eine mit mindestens einem magnetischen Kreis zusammenwirkende Rahmenspule und .ein Paar von Magneten und zwei Paare von Polschuhen aufweist, ist dadurch gekennzeichnet, dass die Magnetisierungsachsen der Magnete rechtwinklig zur Spulenachse stehen und dass die Magnete in unmit telbarer Nähe der Spule angebracht sind, wobei die Felder der Magnete parallel in entgegengesetztem Sinne stehen und wobei die Polschuhe zur Leitung des Magnetfeldes durch die Spule auf den Polflächen der Magnete angebracht sind» ohne über dieselben vorzustehen,,The present invention aims to improve these relationships in a polarized micromotor. This micromotor, the at least one frame coil cooperating with at least one magnetic circuit and .ein pair of magnets and having two pairs of pole pieces is characterized in that the magnetization axes of the magnets are perpendicular to the The coil axis is and that the magnets are in the immediate vicinity the coil are attached, the fields of the magnets are parallel in opposite directions and the pole pieces to Conduction of the magnetic field through the coil on the pole faces of the magnets are attached »without protruding over them ,,

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung.The drawing shows an embodiment of the invention.

Fig. 1 ist eine perspektivische Ansicht des Ausführungsbeispiels und Fig. 1 is a perspective view of the embodiment and

Fig. 2 ist ein Schnitt durch den Magnetkreis und die Spule.Fig. 2 is a section through the magnetic circuit and the coil.

In Fig. 1 ist ein Teil eines Halters mit zwei Schenkeln la und Ib dargestellt, welche Schenkel eine gewisse Elastizität aufweisen. In diesen Schenkeln sind die Enden einer flachen Torsionslamelle 2 eingespannte In ihrer Mitte ist als Schwingmasse ein steifer Stab 3 befestigt» An den Enden des Stabes 3 sind einerseits eine Rahmenspule 4 und anderseits ein nicht dargestelltes Gegengewicht befestigt, derart, dass das System bezüglich der Achse der Torsionslamelle statisch ausgewuchtet ist.In Fig. 1 a part of a holder with two legs la and Ib is shown, which legs have a certain elasticity exhibit. The ends of a flat torsion lamella 2 are clamped in these legs. Its center is an oscillating mass a rigid rod 3 attached »to the ends of rod 3 are on the one hand a frame coil 4 and on the other hand a not shown Counterweight 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« Me Spule wird v<an einem stabilen Oszillator, beispielsweise einem fiuarsossillafcor gespeist»The coil 4 is coupled to a magnetic circuit which has a pair of magnets 5 and 6 as well as two pairs of pole pieces 7, 8 and 9 »10« Me coil is fed to a stable oscillator, for example a fiuarsossillafcor »

Die magnetischen Achsen der Magnete 5 und 6 stehen rechtwinklig zur Spulenachse und diese Magnete befinden sich in unmittelbarer Nähe der Spule 4. Die Felder der Magnete 5 und 6 sind parallel und entgegengesetzt gerichtet. Die Magnete weisen Parallelepipedform auf.The magnetic axes of the magnets 5 and 6 are at right angles to the coil axis and these magnets are in the immediate vicinity of the coil 4. The fields of the magnets 5 and 6 are parallel and oppositely directed. The magnets have a parallelepiped shape.

Die Polschuhe 7,8 und 9,10, die zur Leitung des magnetischen Flusses durch die Spulenseiten dienen, sind auf den Polflächen der Magnete 5 und 6 angebracht und bedecken dieselben ohne darüber hinaus vorzustehen. Die Polschuhe 7-10 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 on the pole faces the magnets 5 and 6 attached and cover the same without protruding beyond. The pole pieces 7-10 are prisms of nearly triangular cross-section »whose side is of greater thickness facing the coil »with which 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 beweglichen magnetischem Kreis getroffen werden*In the illustrated embodiment, the one on the rod 3 fixed coil 3 movable while the magnetic circuit is fixed. However, the arrangement could also be reversed, i.e. be hit with a fixed coil and a moving magnetic circuit *
