Description

Elektro - Kleinstmotor. Small electric motor.

Die Neuerung betrifft einen Elektro-Kleinstmotor, insbesondere einen Gleichstrommotor für 6 bis 12 V Betriebsspannung. The innovation relates to a miniature electric motor, in particular one DC motor for 6 to 12 V operating voltage.

Sie stellt sich die Aufgabe, durch zweckmässige Ausgestaltung eine gedrängte und einfache Bauart des Motors bei Gewährleistung verhältnismässig geringer Gestehungskosten zu erreichen, dabei im allgemeinen aber eine derartige Durchbildung zu tieffen, dass bei weitgehender Verminderung von Leistungsverlusten ein hoher Wirkungsgrad erzielt wird. It sets itself the task of creating a compact and simple design of the engine with guarantee relatively lower To achieve production costs, but generally such a development to deepen that with a substantial reduction of power losses a higher one Efficiency is achieved.

Zwecks Lösung dieser Aufgabe schlägt die Neuerung vor, die Lagerschild des Motors aus Presstoff zu fertigen, so dass die Rotorwelle keiner besonderen Lagerung bedarf, sondern entweder unmittelbar, oder aber unter Zuhilfenehme je einer besonderen Lagerbuchse in den Schilden gelagert werden kann. Um die bei den bekannten Motoren auftretenden schädlichen Radialdrücke der Kohlebürsten zu vermeiden, wird ferner vorgeschlagen, das vordere Presstoff-Lagersohild mit achsparallelen Bohrungen zur Aufnahme der Kohlebürsten zu versehen, derart, dass diese mittels Kontaktfedern in axialer Richtung gegen die auf einer mit Nabe versehenen Kollektorscheibe angeordneten Stromwenderlamellen gepresst werden. To solve this problem, the innovation suggests the end shield of the motor from pressed material so that the rotor shaft does not have any special bearings needs, but either directly, or with the help of a special one Bearing bush can be stored in the shields. To the well-known engines To avoid occurring harmful radial pressures of the carbon brushes is also proposed the front Presstoff-Lagersohild with axially parallel holes for To accommodate the carbon brushes in such a way that they are by means of contact springs in the axial direction against those arranged on a collector disk provided with a hub Commuter blades are pressed.

Sowohl diese, als auohweitere Merkmale der Neuerung, die sich insbesondere auf. die Anordnung der Kontaktfedern innerhalb des vorderen Lagerschildes, sowie auf die Verbindung des Komlektors mit einer auf der Rotorwelle befestigten Ankerhülse beziehen, seien an Hand der Zeichnung erläutert, in der Abb. 1 die Anordnung der Kontaktfedern innerhalb des in einem Schnitt dargestellten vorderen Lagerschildes, Abb. 2 das vordere Lagerschild in Ansicht und Abb. 3 einen Längsschnitt durch die vordere Motorhälfte in vergrößertem Masstabe aufzeigt" Der neuerungsgemäss vorgeschlagene Motor besitzt den aus einer Hülse 1 mit Magnet 2 und je einem vorderen und hinteren Lagerschild 3 bestehenden Stator, sowie den aus der Welle 4 nebst darauf befestigter Ankerhülse 5, den Ankerbleohen 6 mit Wicklung 7 und dem Kollektor bestehenden Rotor. Neuerungsgemäß " send sowohl das hier nicht dargestellte hintere, als auch das aus den Abb. 1 bis 3 ersichtliche vordere Lagersohild 3 aus Tresstoff gefertigte so dass die Welle 4 zweckmässig entweder unmittelbar, oder aber mittels je einer besonderen Lagerbuchse in den Schilden, gelagert werden kann.Both these, as well as additional features of the innovation, which are in particular on. the arrangement of the contact springs within the front end shield, as well as the connection of the Komlektor with an armature sleeve attached to the rotor shaft, are explained with reference to the drawing, in Fig. 1 the arrangement of the contact springs within the front end shield shown in a section, Fig . 2 shows the front end shield in a view and Fig. 3 shows a longitudinal section through the front half of the motor on an enlarged scale Shaft 4 together with the anchor sleeve 5 attached to it, the anchor bolts 6 with it Winding 7 and the collector existing rotor. According to the innovation " send both the rear one, not shown here, as well as that from Figs. 1 to 3 apparent front bearing frame 3 from Made of Tresstoff so that the shaft 4 can be stored either directly or by means of a special bearing bush in each of the shields.

Wie die Neuerung ferner vorschlägt, ist das vordere Lagerschild 3 mit zur Aufnahme der Kohlebürsten 8 dienenden achsparallelen Bohrungen 9 versehen. Die Kohlebürsten 8 werden also mittels der Kontaktfedern lo in axialer Richtung gegen den Kollektor gepresst, der neuerungsgemäss aus einer mit Nabe 11 versehenen Planscheibe 11'nebst den auf der Scheibe 11'angeordneten Stromwenderstegen 12 besteht. As the innovation also suggests, the front end shield is 3 provided with axially parallel bores 9 serving to accommodate the carbon brushes 8. The carbon brushes 8 are thus lo in the axial direction by means of the contact springs pressed against the collector, which according to the innovation consists of a hub 11 provided There is a face plate 11 'in addition to the commutator webs 12 arranged on the plate 11'.

Wie insbesondere aus den Abb. 1 und 2 ersichtlich, sind die die Bürsten 8 beaufschlagenden Kontaktfedern in vorzugsweise zueinander parallelen Nuten 13 des vorderen Lagerschildes 3 angeordnet und jeweils mit je einem, zugleich als Niederhalter der Zugeordneten Feder lo dienenden Kontaktbolzen 14 verbunden. As can be seen in particular from Figs. 1 and 2, they are the brushes 8 acting on contact springs in grooves 13 that are preferably parallel to one another of the front end shield 3 and each with one, at the same time as a hold-down device the Associated spring lo serving contact pin 14 connected.

Eine besonders zweokmässige Ausgestaltung des Motors ergibt sich schliesslich noch dadurch, dass, wie dies Abb. 3 veranschaulicht, die Nabe 11 der Kollektorscheibe 11' mit der Ankerhülse 5 du Verwalzung verbunden ist.Finally, there is a particularly two-dimensional design of the motor still in that, as Fig. 3 illustrates, the hub 11 of the collector disk 11 'is connected to the anchor sleeve 5 du rolling.
