Abstract

Motor has two halves and lower half has foil-shaped insulating substrate on which conductive metal tracks are provided. A connector unit (79) has connector element (91) on the substrate between the end surfaces and is electrically connected to conductor tracks. A connector element (93) is provided on the carrier and is electrically connected to element (91) to connect tracks to electrical energy source. The substrate is bent so as to form a cylindrical housing (29) and is mounted on a carrier (27) near the top end surface. A permanent magnet unit that generates a magnetic field at the location of the conductor tracks is arranged in the upper half of the motor. An Independent claim is also included for the disc drive.

Description

Die Erfindung liegt auf dem Anwendungsgebiet der Kleinantriebe mit Radialfeld-Folien­ wicklung wie zum Beispiel Festplattenantriebe oder Servoantriebe, bei denen es auf eine besondere Laufruhe, eine hohe Drehmomentendichte oder einen hohen Wirkungsgrad ankommt.The invention is in the field of small drives with radial field foils winding such as hard disk drives or servo drives, where there is a particularly smooth running, high torque density or high efficiency arrives.

Die bekannten Verfahren benutzen zur Kontaktierung der einzelnen Phasen Anschluß­ beinchen, die in axialer Richtung heraus geführt sind. Ein Beispiel dazu ist in Fig. 0 skiz­ ziert (Abwicklung einer Phase und gebogenes Paket).The known methods use connection for contacting the individual phases, which lead out in the axial direction. An example of this is sketched in Fig. 0 (processing of a phase and curved package).

Dieses Verfahren birgt den Nachteil, daß der Handhabung des Folienankers bei seiner Herstellung umständlich ist, da es gilt, eine Beschädigung durch Verbiegen der sehr dünnen Anschlüsse zu vermeiden.This method has the disadvantage that the handling of the foil anchor in its Manufacturing is cumbersome because it involves damage by bending the very to avoid thin connections.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Kontaktierung der Anker­ wicklungen zu schaffen, welches deren automatisierte (Massen-) Fertigung wesentlich vereinfacht.The invention has for its object a method for contacting the armature to create windings, which their automated (mass) production essential simplified.

Die Lösung gemäß der Erfindung kommt ohne hervorstehende Anschlußdrähte auf den Wicklungen ausThe solution according to the invention comes without protruding leads on the Windings out

Fig. 1 zeigt die Layouts der Abwicklungen der Ankerwicklungen 1 bis 6. Hierbei repräsen­ tierien die Layouts 1-2, 3-4, und 5-6 die drei Stränge einer dreiphasigen Wicklung. Jeder Strang besteht aus einer doppelseitig mit Kupfer beschichteten flexiblen Folie mit den Innenseiten 1, 3, 5, und den Außenseiten 2, 4, 6. Neu ist hier, daß im Fußbereich der Folienwicklungen Aussparungen 12, sowie Verbindungsbahnen 10 vorgesehen sind. Fig. 2 zeigt schematisch wie diese Aussparungen und Verbindungen nach dem Biegen der Stränge in die zylindrische Form arrangiert sein können. Nämlich so, daß mittels einer Leiterplatte (PCB) (7), welche in die Aussparungen 12 greift eine Kontaktierung der Inneren und äußeren Stränge ermöglicht. Um dieses in der dargestellten Weise zu erreichen, sind die in Umfangsrichtung verlaufenden Verbindungslinien 8 nötig. Auf dem PCB können nun auch die Kontakte heraus geführt werden (8), und Verschaltungen 9 vorgenommen werden (hier: Sternpunkt). Fig. 1 shows the layout of developments of the armature coils 1 to 6. The layouts 1-2 , 3-4 , and 5-6 represent the three strands of a three-phase winding. Each strand consists of a double-sided copper-coated flexible film with the inner sides 1 , 3 , 5 , and the outer sides 2 , 4 , 6 . What is new here is that recesses 12 and connecting tracks 10 are provided in the foot region of the film windings. Fig. 2 shows schematically how these recesses and connections can be arranged after the strands have been bent into the cylindrical shape. Namely so that by means of a printed circuit board (PCB) ( 7 ) which engages in the recesses 12 allows contacting the inner and outer strands. To achieve this in the manner shown, the connecting lines 8 running in the circumferential direction are necessary. The contacts can now also be brought out on the PCB ( 8 ), and interconnections 9 can be made (here: star point).

Fig. 3 zeigt ein solches PCB maßstäblich. In Fig. 4 ist explosionsartig der zylindrische Folienanker bestehen aus den Wicklungen 1. . .6, sowie das darin herein greifende PCB 7 dargestellt. Das PCB wird mittels einer Haltevorrichtung 13 fixiert. Die endgültige Kon­ taktierung erfolgt nun über Kehllötungen 14 realisiert, wie in der Gesamtansicht eines Luftspulenmotors mit Folienwicklung in Fig. 5 gezeigt. FIG. 3 shows such a PCB scale. In Fig. 4, the cylindrical foil armature is explosive and consist of the windings 1 . , , 6 , as well as the PCB 7 engaging therein. The PCB is fixed by means of a holding device 13 . The final contact is now made via fillet joints 14 , as shown in the overall view of an air coil motor with a film winding in FIG. 5.

Die Vorteile der Erfindung liegen darin, daß eine erheblich vereinfachte Montage und Handhabung bei der Serienherstellung von Luftspulenmotoren mit Folienwicklung ermöglicht wird.The advantages of the invention are that a considerably simplified assembly and Handling in the series production of air coil motors with foil winding is made possible.
