Description

Die Erfindung betrifft eine magnetelektrische Kleinlichtmaschine für Fahrräder, Motorräder u. dgl., bei welcher der Anker aus Polstücken besteht, die mit dem einen Polschenkel die Spule innen, mit dem anderen, in der Umfangsrichtung danebenliegenden dagegen außen umfassen, wobei die innenliegenden, Polschenkel durch eine Abkröpfung auf den Durchmesser der außenliegenden Schenkel gebracht sind. Die Erfindung besteht darin, daß der Anker aus einzelnen mit je einem geraden und einem gekröpften Schenkel versehenen Polstücken besteht. Gegenüber denn bekannten Maschinen, dieser Art bringt die Erfindung den Vorteil, daß die Polstücke maschinell vom Band in einem Arbeitsgang ahne Abfall hergestellt werden können und daß die Montage denkbar einfach und billig ist.The invention relates to a magneto-electric small alternator for Bicycles, motorcycles and the like, in which the armature consists of pole pieces that with one pole leg the coil inside, with the other, in the circumferential direction Adjacent, on the other hand, encompass the outside, with the inside, pole legs through a bend are brought to the diameter of the outer leg. the Invention consists in the fact that the anchor from individual with one straight and one cranked legs provided pole pieces. Compared to known machines, of this type, the invention has the advantage that the pole pieces are machined from the strip can be produced in one operation without waste and that assembly is conceivable is easy and cheap.

In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt. Es zeigt Fig. I einen Längsschnitt durch die Maschine nach der Erfindung, Fig. 2 bis 4 eine Ausführungsform der Polstücke. Ein sternförmiger Dauermagnet a bewegt sich in bekannter Weise oberhalb der kreisförmigen Spule b und innerhalb der hier gleichen Durchmesser besitzenden Polschenkel. Nach der Erfindung bestweht der Anker aus einzelnen Polstücken, die die Spule b mit einem geraden Schenkel c außen umfassen, während der andere, auf der Innenseite der Spule liegende Schenkel e durch die Kröpfung d zu dem für den Dauermagneten a erforderlichen Durchmesser aufgeweitet ist. Im Joch sind die Polstücke durch eine Schraube g, die elektrisch isoliert angebracht ist, verbunden, wobei die Schraube gleichzeitig als Stromabnahme ausgebildet ist.Exemplary embodiments of the invention are shown in the drawing. FIG. 1 shows a longitudinal section through the machine according to the invention, FIG to 4 an embodiment of the pole pieces. A star-shaped permanent magnet a moves in a known manner above the circular coil b and within the here Pole legs having the same diameter. According to the invention, the anchor exists from individual pole pieces that enclose the coil b with a straight leg c on the outside, while the other leg e, lying on the inside of the coil, is through the crank d is widened to the diameter required for the permanent magnet a. in the Yoke, the pole pieces are attached by a screw g that is electrically insulated is connected, the screw being designed as a power take-off at the same time.

Das Ankersystem nach der Erfindung kann mit jeder ungeradzahligen Polpaarzahl ausgeführt werden.The anchor system according to the invention can be used with any odd Number of pole pairs.
