Description
Die vorliegende Erfindung betrifft einen Motor und ein Verfahren zur Montage des Motors als Direktantriebselement für ein Wäschebehandlungsgerät.The present invention relates to a motor and a method of assembly the motor as a direct drive element for a laundry treatment appliance.
Wäschebehandlungsgeräte sind u.a. Waschmaschinen, Wäscheschleudern oder Wäschetrockner. Diese Maschinen umfassen eine in einem Bottich drehbar gelagerte Trommel, die motorisch angetrieben wird. Die Trommel ist zur Aufnahme von Waschgut oder Wäsche ausgebildet und in bekannter Weise von vorne oder von oben beschickbar. Als Antriebsmotoren werden heute zunehmend wegen ihrer guten Regelbarkeit und ihrer nahezu unbegrenzten Lebensdauer Direktantriebe (also direkt, d.h. ohne Kraftübertragung mittels Riemen oder Getriebe die Trommelwelle antreibende Motoren) eingesetzt. Direktantriebe können als Außenläufer oder als Innenläufer ausgebildet sein. Beim Direktantrieb entfallen Verschleißteile wie Riemen oder Getriebe. Bei Außenläufermotoren besteht der Stator aus kreisförmig angeordneten Polen (Blechpaketen) mit Isolierung und Polwicklung. Ihm gegenüber stehen permanentmagnetische Pole, die am Innenumfang eines meist glockenförmig ausgebildeten Außenläufers sitzen. Der tatsächliche Luftspalt beträgt z.B. 0,5 - 2 mm. Durch den auf den Umfang des Motors bezogenen kleinen Luftspalt ist sowohl eine genaue Positionierung des Stators zur Trommellagerung als auch eine gute Fixierung nötig. Die Isolierung der Polwicklungen muß die bei Hausgeräten geforderten Kriechstrecken sicher einhalten. Der Rotor (Außenläufer oder Innenläufer) darf bei der Montage nicht mit seinen Magneten auf die Pole des Stators schlagen. Zur Erfüllung dieser Forderungen sind nach dem Stand der Technik z. B. folgende Ansätze bekannt: Laundry treatment appliances are u.a. Washing machines, spin dryers or Dryer. These machines include a rotatably mounted in a tub Drum that is powered by a motor. The drum is for recording formed by laundry or laundry and in a known manner from the front or Chargeable from above. As drive motors are today increasingly because of their good controllability and its almost unlimited life direct drives (ie directly, i.e. without transmission of power by means of belt or gear, the drum shaft driving motors). Direct drives can be used as external rotor or be designed as an internal rotor. The direct drive eliminates wearing parts like belts or gears. In external rotor motors, the stator is circular arranged Poland (laminated cores) with insulation and pole winding. Him opposite there are permanent magnetic poles, which on the inner circumference of a mostly sitting bell-shaped outer rotor. The actual air gap is e.g. 0,5 - 2 mm. By referring to the circumference of the engine small Air gap is both an accurate positioning of the stator for drum storage as well as a good fixation necessary. The insulation of the pole windings must be at Household appliances creepage distances required safely comply. The rotor (external rotor or internal rotor) must not be used with its magnets on the poles during assembly of the stator. To meet these requirements are according to the state of Technology z. B. the following approaches:
Nach der EP 0 361 775 B1 bilden der Stator mit seinen Wicklungen, die Bottichrückwand und das Lagerkreuz mit Lagerbohrung für die Trommelachse eine Einheit. Sie sind als Kunststoffspritzteil mit Einlegeteilen ausgebildet. Nachteilig daran ist eine schlechte Wärmeableitung und ein großer Materialaufwand an kriechstromfestem Kunststoff.According to EP 0 361 775 B1, the stator with its windings forms the rear wall of the tub and the bearing cross with bearing bore for the drum axis one unit. They are designed as plastic injection molded parts with inserts. adversely this is a bad heat dissipation and a large amount of material Non-tracking plastic.
Nach der DE 199 37 229 A1 ist die Trommelachse gegenüber dem Stator für einen zentrischen Sitz extra mit einem Kugellager gelagert. Das zusätzliche Lager bedeutet einen größeren zusätzlichen Aufwand.According to DE 199 37 229 A1, the drum axis is opposite the stator for a centric seat stored extra with a ball bearing. The additional warehouse means a larger additional effort.
Nach der DE 100 56 986 A1 wird für die zentrische Montage der Antriebselemente ein Montageteil z.B. an der Antriebswelle der Tommel befestigt. Es muss nach der Montage gelöst und wieder entfernt werden. Das ist aufwändig.After DE 100 56 986 A1 is for the centric assembly of the drive elements a mounting part e.g. attached to the drive shaft of the drum. It has to go the assembly dissolved and removed again. That's expensive.
Nach der DE 100 60 940 A1 sind für die zentrische Montage des Stators auf dem Tragstern Fortsätze für einen führenden Eingriff in den Stator bei der Montage vorgesehen. Das Lagerkreuz bzw. die Bottichrückwand werden in nachteiliger Weise aufwändig.According to DE 100 60 940 A1 are for the central mounting of the stator on the Cartridge extensions for a leading engagement in the stator during assembly intended. The bearing cross or the tub rear wall are in disadvantageous Way consuming.
Es ist Aufgabe der vorliegenden Erfindung, durch konstruktive Ausbildung einen einfacher zu montierenden Motor zu schaffen und damit ein verbessertes Verfahren für die Montage dieses Motors an ein Wäschebehandlungsgerät zu finden.It is an object of the present invention, by constructive training a easier to install motor and thus an improved process for mounting this motor to a laundry treatment device.
Diese Aufgabe wird erfindungsgemäß durch einen Motor mit den Merkmalen des
Anspruchs 1 und ein Verfahren für seine Montage gemäß Anspruch 10 gelöst.This object is achieved by a motor with the features of
Eine Lagerbohrung in einem Lagerkreuz bzw. einer Bottichrückwand ist für den Sitz von Kugellagern genau bearbeitet. Die Erfindung nutzt diese ohnehin nötige, definierte und glatte Bohrung zur Zentrierung des Stators aus. Damit dies möglich wird, hat der Stator an der zum Bottich zugewandten Seite mittig eine vorzugsweise zylindrische oder kegelige Ausstülpung, die genau in die Bohrung im Lagerkeuz bzw. in der Bottichrückwand passt. A bearing bore in a bearing cross or a tub rear wall is for the Seat of ball bearings accurately edited. The invention uses these anyway necessary, defined and smooth bore for centering the stator. For this possible is, the stator on the side facing the tub in the middle of a preferably cylindrical or conical protuberance, which is exactly in the bore in Lagerkeuz or fits in the tub rear wall.
Der Stator kann aus z.B. zwei elektrisch isolierenden Kunststoffschalen, die das Blechpaket tragen, zusammengesetzt sein.The stator may be made of e.g. two electrically insulating plastic shells that the Carrying laminated core, be composed.
Die beiden Kunststoffschalen, eine innere Schale und eine äußere Schale sind präzise Spritzteile. Die innere Schale hat mittig die Ausstülpung, die genau in die Lagerbohrung passt. Die beiden Kunststoffschalen bilden zusätzlich zu ihrer Haltefunktion die Isolierung für die Polwicklungen der Statorpole. Damit der nötige große Kriechstromweg zwischen Statorblechpaket und Statorwicklung eingehalten werden kann, überlappen sich die beiden Kunststoffschalen.The two plastic cups, an inner shell and an outer shell are precise molded parts. The inner shell has in the middle the protuberance, which is exactly in the Bearing bore fits. The two plastic shells in addition to their holding function the insulation for the pole windings of the stator poles. So the necessary large creepage current path between stator laminated core and stator winding complied with can be, overlap the two plastic shells.
Bei der Fertigung des Stators wird das Blechpaket in die Schalen gelegt. Die beiden Schalen halten durch Rastnasen (z.B. an der inneren Schale) zusammen. Nach der Bewicklung der Pole kann der komplette Stator mit der inneren Ausstülpung zentrisch auf den Tragstern gesetzt werden und herkömmlich, z.B. mit Schrauben, fixiert werden. Diese Schrauben sind durch die beiden Abstandhalter der äußeren Kunststoffschale in das Lagerkreuz bzw. die Bottichrückwand geschraubt. Damit sind sie gegen das Blechpaket des Stators isoliert.When manufacturing the stator, the laminated core is placed in the shells. The two Shells hold together by detents (e.g., on the inner shell). To the winding of the poles can be the complete stator with the inner protuberance be placed centrally on the supporting star and conventional, e.g. with screws, be fixed. These screws are through the two spacers of the outer Plastic shell screwed into the bearing cross or the tub rear wall. In order to they are insulated against the laminated core of the stator.
Die äußere Kunststoffschale gemäß Weiterbildung der Erfindung hat oberhalb der Polisolierung in Richtung zur Läuferglocke z.B. ausgespritzte Nasen. Der Außendurchmesser über die Nasen entspricht dem Innendurchmesser einer Rotorglocke mit ihren permanentmagnetischen Polen. Erfindungsgemäß dienen diese Nasen zu einer problemlosen Montage der Rotorglocke. Die Rotorglocke wird über die Nasen in Richtung Trommel geschoben. Dabei schiebt sich das Innenloch der Glocke auf die Trommelachse und die Rotorglocke wird so zentrisch gehalten. Sie kann selbst durch die magnetischen Kräfte der permanentmagnetischen Pole getrieben nicht auf die weichmagnetischen Pole des Ständers schlagen. Somit ist eine Beschädigung der Permanentmagnete der Rotorglocke ausgeschlossen. Ist die Rotorglocke ganz aufgeschoben, stehen die Nasen seitlich nach außen versetzt neben den permantmagnetischen Polen der Rotorglocke in deren Innenraum. Die Rotorglocke kann sich frei drehen. Sie ist auf der Trommelachse in jeder herkömmlichen Weise, z.B. mit einer Mutter, fixierbar. Für einen Innenläufer gilt in analoger Weise das gleiche Prinzip, wie für den oben beschriebenen Außenläufer.The outer plastic shell according to the invention has above the Polisolierung towards the rotor bell, e.g. spouted noses. The outer diameter over the noses corresponds to the inner diameter of a rotor bell with their permanent magnetic poles. According to the invention, these noses serve too a trouble-free assembly of the rotor bell. The rotor bell is over the noses pushed in the direction of the drum. This pushes the inner hole of the bell on the drum axis and the rotor bell is kept so centric. she can itself driven by the magnetic forces of the permanent magnetic poles do not hit the soft magnetic poles of the stator. Thus, a damage the permanent magnets of the rotor bell excluded. Is the rotor bell completely pushed, the noses are laterally offset outwards the permanent magnet poles of the rotor bell in the interior. The rotor bell can turn freely. She is on the drum axis in every conventional Way, e.g. with a nut, fixable. For an internal rotor is valid in analog The same principle as for the external rotor described above.
Die Nasen auf der äußeren Kunststoffschale müssen nicht ausgespritzt sein. Die gleiche Montage ist mit einem Nasenteil z.B. aus Kunststoff, das an der äußeren Schale angeschnappt wird, möglich. In diesem Fall könnten die Polwicklungen für die Statorpole unabhängig von diesem gewickelt werden und vor dem Befestigen des Nasenteils über die Pole geschoben werden.The noses on the outer plastic shell need not be injected. The same assembly is with a nosepiece, e.g. made of plastic, which is on the outside Shell is snapped, possible. In this case, the pole windings for the stator poles are wound independently of this and before attaching of the nose part are pushed over the poles.
Das Prinzip der Erfindung, den Stator in der Lagerbohrung des Lagerkreuz bzw. der Bottichrückwand zu zentrieren, kann man auch mit einem Hilfsteil zur Montage des Stators verwirklichen. Das Hilfsteil hat dann mittig die vorzugsweise zylindrische oder kegelige Ausstülpung, die genau in die Lagerbohrung passt. Das Hilfsteil könnte z.B. als Glocke ausgebildet sein, in die der Stator mit seinem größten Außendurchmesser gerade hineinpasst. Der komplette Stator würde zusammen mit dem Hilfsteil auf das Lagerkreuz bzw. die Bottichrückwand geschoben und dann z.B. mit Schrauben durch Löcher im Hilfsteil festgeschraubt. Danach würde das Hilfsteil wieder abgezogen und der Läufer wie oben beschrieben montiert.The principle of the invention, the stator in the bearing bore of the bearing cross or To center the tub rear wall, you can also with an auxiliary part for mounting of the stator. The auxiliary part then has the middle preferably cylindrical or conical protuberance that fits exactly in the bearing bore. The Auxiliary part could e.g. be designed as a bell into which the stator with his largest outer diameter just fits. The complete stator would work together pushed with the auxiliary part on the bearing cross or the tub rear wall and then, e.g. screwed with screws through holes in the auxiliary part. After that would the auxiliary part withdrawn and the runner as described above assembled.
Unter Verwirklichung einiger der vorstehend beschriebenen Merkmale ergibt sich so ein Verfahren zur Montage eines Motors als Direktantrieb für ein Wäschebehandlungsgerät, bei dem der Stator ohne zusätzliche Behandlung eines weitgehend herkömmlichen Lagersystems einfach genau zentrisch montierbar ist und sich die Läuferglocke ohne Gefahr einer Beschädigung ihrer Permanentmagnete montieren läßt.Realizing some of the features described above results such a method of mounting a motor as a direct drive for a laundry treating appliance, in which the stator without additional treatment of a largely conventional storage system is easy to install exactly centric and the rotor bell without risk of damage to their permanent magnets can assemble.
