Der Lüfter 20 hat ein unteres Gehäuseteil (Basisteil, Trägerteil) 22, und ein oberes Gehäuseteil (Luftführungsteil) 24, welches mit dem unteren Gehäuseteil 22 z. B. über eine Klebeverbindung, Schweißverbindung Rastverbindung und/oder eine Schnappverbindung verbunden ist. An dem Lüfter 20 bzw. bevorzugt an der Unterseite des unteren Gehäuseteils 22 sind Verbindungselemente 25 zur Befestigung des Lüfters 20 an einer Leiterplatte oder einem Gehäuseteil vorgesehen, z.B. in Form von Rastelementen wie z.B. Rastbolzen und/oder Rasthaken.The
Das untere Gehäuseteil 22 hat in der Mitte ein Lagertragrohr 26, in das ein Sinterlager 28 eingepresst ist. Alternativ können als Lager 28 z. B. auch ein oder mehrere Wälzlager oder ein Keramiklager verwendet werden. Im radial äußeren Bereich des unteren Gehäuseteils 22 ist mindestens ein Magnet 50 zur Erzeugung eines magnetischen Hilfsmoments angeordnet, der bei nicht bestromtem Stator 40 und ruhendem Rotor 60 eine definierte Rotorstellung gewährleistet.The
Auf der Außenseite des Lagertragrohrs 26 ist ein Innenstator 40 befestigt, der einen bevorzugt aus Kunststoff gefertigten Träger (Spulenkörper) 42 mit einer Statorwicklung 44, einem oberen Klauenpolteil 46, einem unteren, um 90 ° verdrehten - nicht dargestellten - Klauenpolteil 46' und vier im Träger 42 befestigten, zur Außenseite des unteren Gehäuses 22 ragende Anschlussstifte 51, 52, 53 und 54 hat, vgl.
Die Statorwicklung 44 hat - nur schematisch angedeutet - einen Antriebsstrang 48 und eine Sensorspule 49, welche kreisförmig um das Lagertragrohr 26 herum auf den Träger 42 aufgewickelt sind, um zusammen mit den Klauenpolenteilen 46, 46' einen Klauenpolstator 40 zu bilden.The stator winding 44 has - only schematically indicated - a
Der Strang 48 dient als Antriebsstrang zum Antrieb des Motors und hat zwei Anschlüsse (Enden) 48' bzw. 48", die z. B. mit den Anschlussstiften 51 bzw. 53 elektrisch verbunden sind. Die Spule 49 dient als Sensorspule zur Erfassung der Rotorstellung für die elektronische Kommutierung und hat zwei Anschlüsse (Enden) 49', 49", die z. B. mit den Anschlussstiften 52 bzw. 54 elektrisch verbunden sind. Dargestellt sind nur die Anschlüsse 48' und 49', die um die Anschlussstifte 51 und 52 gewickelt und mit diesen verlötet sind. Bevorzugt hat die Verbindung der Enden 48', 48", 49' und 49" mit den Anschlussstiften 51 bis 54 eine Zugentlastung, um eine Beschädigung der Enden zu verhindern.The
Bevorzugt werden auf dem Träger 42 die Statorwicklung 44, die Klauenpolteile 46, 46' und die Anschlussstifte 51 bis 54 vormontiert, und der vormontierte Träger 42 wird anschließend auf das Lagertragrohr 26 geschoben und z. B. über vier - nicht dargestellte - Zapfen in entsprechenden Löchern des unteren Gehäuseteils 22 zur mechanischen Verbindung eingepresst.Preferably, on the
Ein Außenrotor 60 hat eine Rotorglocke 62, innerhalb deren ein ringförmiger Dauermagnet 64 angeordnet ist, der in diesem Ausführungsbeispiel vierpolig magnetisiert ist, da auch der Klauenpolstator 40 vier Pole hat. Der Dauermagnet 64 ist z.B. als kunststoffgebundener Ferritmagnet ("Gummimagnet") ausgeführt, und er wird z.B. in den Rotor 60 eingespritzt oder eingeklebt, wobei beim Spritzen kleinere Toleranzen möglich sind.An
In der Rotorglocke 62 ist eine Welle 66 befestigt, die im Sinterlager 28 gelagert ist und eine Drehung bezüglich der Motorachse bzw. Rotorachse 70 (
Auf der Rotorglocke 62 sind im Wesentlichen radial verlaufende Lüfterflügel 68 eines Radiallüfters angeordnet. Die Lüfterflügel 68 können auch eine Krümmung in die Laufrichtung oder gegen die Laufrichtung des Lüfters 20 aufweisen.On the
Das obere Gehäuseteil 24 hat oben eine zentrale Lufteintrittsöffnung 30 zum im Wesentlichen axialen Einlass von Luft 31 und mindestens eine seitliche Luftaustrittsöffnung 32 zum im Wesentlichen radialen Auslass von Luft. Am Rand der Lufteintrittsöffnung 30 bildet das obere Gehäuseteil 24 mindestens bereichsweise einen Kragen 34, und um den Kragen 34 herum hat sie eine flache Oberseite 36.The
Eine Leiterplatte 80 ist auf der flachen Oberseite 36 des oberen Gehäuseteils und bevorzugt oberhalb des Rotors 60 und des Stators 40 angeordnet. Die Leiterplatte 80 ist ringförmig um den Kragen 34 herum angeordnet und hat einen ringförmigen Bereich 87 (
An einem ersten Anschlussbereich 81 ist sie mit vier axial verlaufenden, an der Außenseite des unteren Gehäuseteils 22 und des oberen Gehäuseteils 24 befestigten, axial verlaufenden Kontaktstiften 91, 92, 93, 94 verbunden, indem diese z.B. durch entsprechende Löcher in der Leiterplatte 80 hindurchragen und auf der Oberseite der Leiterplatte 80 mit entsprechenden Kontakten 191, 192, 193 und 194 kontaktiert, bevorzugt verlötet sind, vgl.
Auf der Leiterplatte 80 sind - schematisch angedeutete - Leiterbahnen 86 und elektrische/elektronische Bauteile 88 angeordnet.On the circuit board 80 - printed circuit traces 86 and electrical /
Bevorzugt ist auf der Leiterplatte 80 die gesamte Motorelektronik für den elektronisch kommutierten Lüfter 20 angeordnet, welche z. B. das Signal der Sensorspule 49 auswertet und über eine Endstufe die Bestromung des Antriebstrangs 48 steuert, um eine Drehung des Rotors 60 zu bewirken. Hierzu wird die Leiterplatte 80 bevorzugt nur mit SMD-Bauteilen 88 bestückt, und die Leiterbahnen 86 sind sowohl auf der Oberseite als auch auf der Unterseite der Leiterplatte vorgesehen, wobei entsprechende Durchkontaktierungen vorgesehen sind. Die Leiterplatte 80 hat bevorzugt eine Dicke von 2 mm +/- 1 mm und im ringförmigen Bereich außerhalb des ersten Anschlussbereichs 81 und des zweiten Anschlussbereichs 82 einen inneren Durchmesser im Bereich von 15 mm bis 35 mm und einen äußeren Durchmesser im Bereich von 18 mm bis 40 mm, wobei die radiale Erstreckung zwischen dem inneren und dem äußeren Rand der Leiterplatte 80 bevorzugt im Bereich 4 mm +/- 2 mm liegt. Bevorzugt erstreckt sich die Leiterplatte 80 radial maximal bis zum Gehäuse 22, 24, wobei jedoch der erste Anschlussbereich 81 und der zweite Anschlussbereich 82 radial darüber hinaus vorstehen können, vgl.
Die Drehung des Rotors 60 mit den Lüfterflügeln 68 bewirkt ein Ansaugen von Luft durch die Lufteintrittsöffnung 30 und ein Ausblasen der Luft durch die seitlichen Öffnungen 32. Somit kann z. B. Luft aus dem Inneren eines Fahrzeugs angesaugt und mittels des Sensors 84 deren Temperatur gemessen und über die Kontakte 95, 96 einer - nicht dargestellten - Klimaanlage zugeführt werden.The rotation of the

Der Motor und die Kommutierungselektronik stellen einen 1-strängigen, 1-pulsigen Antrieb dar, bei dem jeweils über ca. 180 °el. der Antriebsstrang 48 bestromt wird, während er über die anderen ca. 180 °el. stromlos bleibt, wobei der Zeitpunkt für die Kommutierung über die Sensorspule 49 ermittelt wird.The motor and the commutation electronics represent a 1-stranded, 1-pulse drive, in each case about 180 ° el. the
Der Motor kann nur in bestimmten Startpositionen anlaufen, und diese werden durch die von dem mindestens einen Magneten 50 erzeugten magnetischen Hilfsmomente sichergestellt. Der Motor hat eine Vorzugsdrehrichtung.The motor can start only in certain starting positions, and these are ensured by the magnetic auxiliary moments generated by the at least one
Die Dioden 158, 162 und 164 schützen die Transistoren 156, 172 und 184 vor Zerstörung, und die Diode 186 schützt vor einer Verpolung der Betriebsspannung.The
Die Transistoren 156, 172 bilden einen so genannten Stromspiegel, und der als Diode ausgelegte Transistor 156 bewirkt eine exakte Vorspannung an der Basis des Transistors 172. Im Folgenden bezeichnet der Strom 11 den Strom durch den Widerstand 152, der Strom I2 den Strom durch den Widerstand 168 und der Strom I3 den Strom durch den Antriebsstrang 48. Der Strom 11 wird bestimmt durch die angelegte Betriebsspannung und den Widerstand 152. Solange in der Sensorspule 49 keine Spannung induziert wird (Drehzahl n = 0), liegen die Basis des Transistors 156 und die Basis des Transistors 172 durch die Sensorspule 49 auf dem gleichen Potenzial, und die Ströme I1 und I2 sind daher ungefähr gleich groß. Nach dem Einschalten der Betriebsspannung ist jedoch die Spannung an der Basis des als Endstufe arbeitenden Transistors 184, welche durch den Widerstand 174 und den Kollektor des Transistors 172 mitbestimmt wird, aufgrund der Unsymmetrie der Widerstände 168 und 152 minimal größer, und daher schaltet der Transistor 184 ein. Dadurch wird der Antriebsstrang 48 bestromt, und der Rotor 60 beginnt sich zu drehen. Hierdurch wird in der Sensorspule 49 eine Spannung induziert, und bei dem anschließenden Nulldurchgang dieser induzierten Spannung (induzierte Spannung wird positiv) wird der Transistor 172 voll eingeschaltet. Dadurch wird das Potenzial an der Basis des Transistors 184 reduziert, und dies hat zur Folge, dass durch den Antriebsstrang 48 kein Strom mehr fließt. Aufgrund des Trägheitsmoments des Rotors 60 dreht sich dieser weiter bis zum darauf folgenden Nulldurchgang der induzierten Spannung (induzierte Spannung wird negativ). Daraufhin sperrt der Transistor 172, und dies hat zur Folge, dass der Transistor 184 wieder leitend wird, und der Antriebsstrang 48 bestromt wird. Die Ein- und Ausschaltzeitpunkte des Transistors 184 werden also durch die Nulldurchgänge der in der Sensorspule 49 induzierten Spannung bestimmt.
Bei der Anordnung der Bauteile auf der ringförmigen Leiterplatte 80 haben sich auf Grund des geringen Platzes Probleme ergeben, und zur Lösung haben sich die folgenden Prinzipien als vorteilhaft erwiesen:
- Die Schalter (Transistoren, MOSFETs etc.) der Auswerteelektronik für die Rotorstellung werden in einem Winkelabstand bezüglich der ringförmigen Leiterplatte von maximal 150 ° angeordnet.
- Bei einer Endstufe mit mindestens zwei Schaltern (Transistoren, MOSFETs etc.) werden die Schalter in einem Winkelbereich bezüglich der ringförmigen Leiterplatte 80 von maximal 150 ° angeordnet.
- Auf der Unterseite der Leiterplatte 80 sind außer den Leiterbahnen keine elektrischen/elektronischen Bauteile angeordnet.
- Es gibt mindestens einen Winkelbereich des ringförmigen Teils 87
der Leiterplatte 80, in dem nur ein elektrisches/elektronisches Bauteil auf dem angeordnet ist. - Alle elektrischen/elektronischen Bauteile sind so angeordnet, dass sich deren Winkelbereiche bezüglich der ringförmigen Leiterplatte nicht überlappen.

Fig. 9 istsie als Linie 210 sichtbar), auf der die Rotorachse liegt und welche die ringförmige Leiterplatte in zwei Teile teilt (bzw. im Wesentlichen halbiert), wobei der mindestens eine Halbleiterschalter 156,172 (Transistor, MOSFET etc.) der Rotorstellungssensorik auf dem einen Teil und der mindestens eine Halbleiterschalter 184 (Transistor, MOSFET etc.) der Endstufe auf dem anderen Teil angeordnet ist. Die gedachte Ebene 210 verläuft bei einer Leiterplatte 80 mit einem ersten Anschlussbereich 81 für die Wicklung und einem zweiten,dem ersten Anschlussbereich 81 gegenüberliegenden Anschlussbereich 82 für die Betriebsspannung und ggf. die Sensorkontakte durch den erstenAnschlussbereich 81 und den zweitenAnschlussbereich 82 hindurch. D.h., dass auf dem einen Halbkreis zwischenden Anschlussbereichen 81 und 82 der oder die Halbleiterschalter für die Rotorstellungssensorik und auf dem anderen Halbkreis die Halbleiterschalter für die Endstufe angeordnet sind.

Die Anordnung der Bauteile und insbesondere der elektronischen Bauteile 162, 172, 184 auf der Leiterplatte 80 geschieht bevorzugt derart, dass sie alle bei Draufsicht auf den Lüfter entlang der Motorachse innerhalb des Gehäuses an der entsprechenden Stelle sind. Mathematisch ausgedrückt ist bei Draufsicht auf den Lüfter entlang der Motorachse 70 bei jedem Winkel (d.h. um die ganze Leiterplatte herum, vgl. Winkelbereich 212) bezüglich der Leiterplatte 80 die maximale radiale Erstreckung der sich auf der Leiterplatte 80 befindenden elektronischen Bauteile 156, 172, 184 der Motorelektronik 88 kleiner ist als die entsprechende maximale radiale Erstreckung des Gehäuses 22, 24.
