Description

Magnetsystem für elektrische, mit rotierender Wicklung versehene Kleinlichtmaschinen Die Erfindung betrifft ein Magnetsystem für solche elektrische, mit rotierender (umlaufender) Wicklung versehene Kleinlichtmaschinen, die mit zweipoligen, stabförmig gestalteten und der Form des Läufers und der Polschuhe angepaßten Magneten versehen sind.Magnet system for electric small alternators with rotating windings The invention relates to a magnet system for such electrical, with rotating (circumferential) winding provided small alternators with two-pole, rod-shaped designed and the shape of the rotor and the pole pieces adapted magnets are.

Feststehende Magnetsysteme mit zweipoligen, stabförmig gestalteten Magneten, die der Form des Läufers angepaßt sind und von ihnen angepaßten Polschuhen gehalten werden, sind bereits bekannt. Dabei ergibt sich jedoch, abgesehen davon, daß die Magnete nicht wenigstens an zwei ihrer Flächen von dien Polschuhen eingeschlossen werden, der Mangel, daß die Magnete nicht einfach von einem Werkstoffstab abgeschnitten werden können, viehmehr eine genaue Flächenbearbeitung erfolgen ruß.Fixed magnet systems with two-pole, rod-shaped designs Magnets which are adapted to the shape of the rotor and pole pieces adapted from them are already known. However, apart from that, this results in that the magnets are not enclosed by the pole pieces on at least two of their faces the shortcoming that the magnets are not simply cut off from a rod of material can be done, cattle more precise surface treatment soot.

Demgegenüber kennzeichnet sich das Magnetsystem gemäß der Erfindung dadurch, daß die stabförmigen Magnete an mindestens zwei oder mehreren Flächen ihrer Pole von den Polschuhen eingeschlossen sind. Die Erfindung bietet den Vorteil, daß die stabförmigen Magnete unbearbeitet bleiben können.In contrast, the magnet system is characterized according to the invention in that the rod-shaped magnets on at least two or more surfaces of their Poles are enclosed by the pole pieces. The invention offers the advantage that the rod-shaped magnets can remain unprocessed.

Das Magnetsystem für elektrische Kleinlichtmaschinen gemäß der Erfindung ist in der Zeichnung in verschiedenen Ausführungsbeispielen veranschaulicht.The magnet system for small electric alternators according to the invention is illustrated in the drawing in various exemplary embodiments.

Abb. i ist ein Schnitt nach der Linie rl-B von Abb.2 und Abb. 2 ,eine Draufsicht auf Abb. i ; Abb. 3 ist ein Schnitt nach der Linie C-1) von Abb. q. und Abb. q. eine Draufsicht auf Abb. 3 ; Abb. 5 ist ein Schnitt nach der Linie E-F von Abb. 6 und Abb. 6 eine Draufsicht auf Abb. 5.Fig. I is a section along the line rl-B of Fig.2 and Fig. 2, a Top view of Fig. I; Fig. 3 is a section along the line C-1) of Fig. Q. and Fig.q. a top view of Fig. 3; Fig. 5 is a section on the line E-F of Fig. 6 and Fig. 6 are a plan view of Fig. 5.

Bei der Ausführung des Magnetsystems nach Abb. i und 2 besitzen die stabförmigen, d. h. einfach vom Werkstoffsaab abgeschnittenen Magnete i einen rechteckigen Querschnitt; sie schließen in bekannter Weise den Läufer ein. Diese Magnete haben in bekann ter Weise eine Koerzitivkraft von mehr als 25o 0exsted und werden erfindungsgemäß an mindestens zwei Flächen ihrer Pole von den Polschuhen 2 eingeschlossen.In the design of the magnet system according to Fig. I and 2, the rod-shaped, d. H. simply cut from the material saab magnets i a rectangular one Cross-section; they include the runner in a known manner. Have these magnets in a known manner a coercive force of more than 25o 0exsted and are according to the invention enclosed by the pole pieces 2 on at least two surfaces of their poles.

Bei der Ausführung des Magnetsvstems nach den Abb.3 und .l besitzen die Stab förmigen Magnete 3 den Querschnitt eines Vierkants, sie schließen ebenfalls in bekann ter Weise den Läufer ein und sind erfindungsgemäß ebenfalls an mindestens zwei Flächen ihrer Pole von den Polschuhen .l eingeschlossen.When designing the magnetic system according to Figs the rod-shaped magnets 3 the cross-section of a square, they also close in a well-known manner the runner and are also according to the invention at least two faces of their poles enclosed by the pole pieces.

Die Ausführung des Magnetsystems nach den Abb. 5 und 6 unterscheidet sich bei Benutzung von beispielsweise drei stabförmigen Magneten i nur dadurch von der Ausführung nach Abb. i und 2, daß die die Magnete i .an mehreren Flächen ihrer Pole einschiießenden Polschuhe 2 ein- oder beidseitig Decklamellen 5 besitzen.The design of the magnet system according to Figs. 5 and 6 differs If, for example, three rod-shaped magnets i are used, this is only possible because of this the execution according to Fig. i and 2, that the magnets i .an several surfaces of their Pole enclosing pole shoes 2 have cover lamellas 5 on one or both sides.
