Die Erfindung betrifft einen bürstenlosen Gleichstrommotor, der eine Wicklung aufweist und der zwischen der Wicklung und dem Rotor keine weiteren Teile besitzt, so daß die Wicklung während des Zusammenbaus nicht beschädigt wird.The invention relates to a brushless DC motor which has a winding and which has no further parts between the winding and the rotor, so that the winding is not damaged during assembly.
Ein Ausführungsbeispiels des erfindungsgemäßen bürstenlosen Gleichstrommotors ist in der Zeichnung dargestellt und wird nachfolgend beschrieben. Es zeigt:An embodiment of the brushless DC motor according to the invention is shown in the drawing and is described below. It shows:
Figur 1 eine räumliche Explosionsdarstellung des bürstenlosen Gleichstrommotors,Figure 1 is an exploded view of the brushless DC motor,
Figur 2 eine Ansicht des bürstenlosen Gleichstrommotors in = Blickrichtung von oben, undFigure 2 is a view of the brushless DC motor in = viewing direction from above, and
Figur 3 einen Schnitt durch den bürstenlosen Gleichstrommotor.Figure 3 shows a cross section of the brushless DC motor.
Der bürstenlose Gleichstrommotor weist eine elektrische Schaltungsplatte 4 auf, die mit drei Öffnungen 41 ausgebildet ist. Eine Wicklung 23 ist an einer Buchse 24 einer Spule 2 angeordnet. Die Buchse 24 weist einen hohlen Innenraum 25 auf,The brushless DC motor has an electrical circuit board 4 formed with three openings 41. A winding 23 is arranged on a socket 24 of a coil 2. The socket 24 has a hollow interior 25,
der zur Aufnahme eines Rohres 3 vorgesehen ist. Die Spule 2 besitzt zwei Endplatten 20, von welchen jede drei Kerben 21 und drei Vorsprünge 22 besitzt, die am äußeren Randabschnitt ausgebildet sind. Die untere Endplatte 20 weist drei Schenkel 26 auf, von welchen jeder mit einem Haken 261 versehen ist, die zum Eingreifen in die Öffnungen 41 der elektrischen Schaltungsplatte 4 vorgesehen sind, um die Spule 2 an der elektrischen Schaltungplatte 4 festzulegen.which is intended to receive a tube 3. The coil 2 has two end plates 20, each of which has three notches 21 and three projections 22 formed on the outer edge portion. The lower end plate 20 has three legs 26, each of which is provided with a hook 261 intended to engage the openings 41 of the electrical circuit board 4 to fix the coil 2 to the electrical circuit board 4.
Zwei Stator-Magnet-Joche 1 sind jeweils mit einer Bohrung 13 ausgebildet, die zum Einsetzen des Rohres 3 dienen, und von welchen jedes drei Öffnung 12 aufweist, die zum Ankuppeln der Vorsprünge 22 vorgesehen sind, wodurch sich eine Befestigung an der Spule ergibt. Jedes der beiden Stator-Magnet-Joche 1 ist mit drei sich radial erstreckenden Verlängerungen 10 ausgebildet, von welchen jede mit einer gebogenen Spitze 11 ausgebildet ist, die relativ zu den Verlängerungen geneigt sind, um ein Ankuppeln an die Kerben 21 der Spule 2 zu ermöglichen, wodurch die Befestigung der Stator-Magnet-Joche 1 an der Spule 2 weiter verbessert wird. Ein Rotor 5 weist eine Spindel 51 auf, die in dem Rohr 3 drehbar vorgesehen ist.Two stator magnet yokes 1 are each formed with a bore 13 for insertion of the tube 3, and each of which has three openings 12 provided for coupling the projections 22, thereby providing attachment to the coil. Each of the two stator magnet yokes 1 is formed with three radially extending extensions 10, each of which is formed with a curved tip 11 inclined relative to the extensions to enable coupling to the notches 21 of the coil 2, thereby further improving the attachment of the stator magnet yokes 1 to the coil 2. A rotor 5 has a spindle 51 rotatably provided in the tube 3.
Die Spitzen 11 der Stator-Magnet-Joche 1 sind nur in die Kerben 21 der Endplatten 20 eingekuppelt, sie erstrecken sich nicht zum äußeren Umfangsrand der Wicklung 23 (Fig. 3), so daß zwischen der Wicklung 23 und dem Rotor 5 keine anderen Teile oder Verlängerungen vorgesehen sind. Das bedeutet, daß die Stator-Magnet-Joche 1 an den Endplatten 20 einfach und leicht befestigt werden können, ohne daß die Wicklung 23 beschädigt wird.The tips 11 of the stator magnet yokes 1 are only engaged in the notches 21 of the end plates 20, they do not extend to the outer peripheral edge of the winding 23 (Fig. 3), so that no other parts or extensions are provided between the winding 23 and the rotor 5. This means that the stator magnet yokes 1 can be simply and easily attached to the end plates 20 without damaging the winding 23.
