Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren gemäß Oberbegriff Patentanspruch 1 sowie auf eine elektrische Maschine gemäß Oberbegriff Patentanspruch 17 oder 19.The The invention relates to a method according to the preamble of the patent claim 1 and to an electric machine according to the preamble of claim 17 or 19.
Zur
Erhöhung
der Leistung einer elektrischen bzw. elektrodynamischen Maschine
ist bereits bekannt, an der dem Rotor zugewandten Innenfläche eines
den Rotor umschließenden
Stators bzw. an der Innenfläche
des Stator-Blechpaketes ein sogenanntes Spaltrohr vorzusehen, d.h.
einen kreiszylinderförmigen
Wandabschnitt, der die im Blechpaket ausgebildeten und zum Rotor
hin offenen Nuten für
die Aufnahme der Abschnitte oder Leiter der Statorwicklung zum Maschinenspalt
zwischen dem Stator und Rotor abdichtet. Der von den elektrischen
Leitern der Wicklung nicht eingenommene Teil jeder Nut kann dann als
Kanal eines Kühlkanalsystems
verwendet werden, welches von einem geeigneten, elektrisch nicht leitenden
Kühlmedium
durchströmt
wird (
Nachteilig hierbei ist, dass das Spaltrohr, d.h. der das Maschinenelement an seiner Spaltfläche im Bereich der Nuten abschließende Wandabschnitt nur unzureichend mit der Innenfläche des den Rotor umgebenden Blechpakets verbunden ist, es hierdurch bereits nach kürzerer Betriebsdauer zu einem Lösen des Spaltrohres von dem Blechpaket und dann zu einer Beschädigung des Spaltrohres durch den umlaufenden Rotor kommt, so dass schließlich auch ein dichtes Kühlkanalsystem nicht mehr gewährleistet ist. Probleme bestehen auch in Bezug auf die Abdichtung des Kühlkanalsystems zu anderen Elementen des Stators bzw. des Statorgehäuses.adversely here it is that the can, i. to the machine element his cleavage surface in the area of the grooves final Wall section insufficiently with the inner surface of the rotor surrounding Blechpakets is connected, it thereby already after a shorter service life to a release of the Canned from the laminated core and then to damage the Canned by the rotating rotor comes, so that finally too a dense cooling channel system is no longer guaranteed. Problems also exist with respect to the sealing of the cooling channel system to other elements of the stator or the stator housing.
Aufgabe der Erfindung ist es, ein Verfahren aufzuzeigen, welches diese Nachteile vermeidet. Zur Lösung dieser Aufgabe ist ein Verfahren entsprechend dem Patentanspruch 1 ausgebildet. Eine elektrische Maschine ist Gegenstand des Patentanspruchs 17 oder 19.task The invention is to provide a method which has these disadvantages avoids. To the solution This object is a method according to the claim 1 formed. An electric machine is the subject of the patent claim 17 or 19.
Die erfindungsgemäße elektrische Maschine ist beispielsweise ein Motor, z.B. ein Synchronmotor, Asynchronmotor oder Gleichstrommotor. Bevorzugt ist die erfindungsgemäße Maschine eine solche mit einem die Wicklung aufweisenden Stator und mit einem von dem Stator umschlossenen Rotor oder aber mit einem den Stator umschließenden Rotor.The electrical according to the invention Machine is for example a motor, e.g. a synchronous motor, asynchronous motor or DC motor. The machine according to the invention is preferred such with a stator having the winding and with a Rotor enclosed by the stator or with one the stator enclosing Rotor.
Bei der erfindungsgemäßen Maschine ist das die Wicklung aufweisende Maschinenelement zumindest an seiner den Maschinenspalt begrenzenden Fläche aus einem elektrisch isolierenden Material, nämlich aus Kunststoff gefertigt, und zwar gemäß einer ersten Ausführungsform der Erfindung unter Verwendung eines rohrartigen Wandabschnitts (Spaltrohres), welcher mit nutenartigen Vorsprüngen in Nuten zur Aufnahme der Leiter der Wicklung hineinreicht und dort formschlüssig gehalten ist, so dass auch die Gefahr eines Lösens dieses Wandabschnittes von dem die Nuten aufweisenden Maschinenelementkörper oder Blechpaket nicht besteht.at the machine according to the invention is the machine element having the winding at least at its the machine gap limiting surface of an electrically insulating Material, namely made of plastic, according to a first embodiment the invention using a tubular wall section (can), which with groove-like projections in Grooves for receiving the head of the coil extends in there and there form-fitting is held, so that the risk of loosening this wall section from the grooves having machine element body or laminated core not consists.
Entsprechend einer weiteren generellen Ausführungsform der Erfindung ist der die Wicklung aufweisende und die Magnetpole bildende Maschinenelementkörper aus Kunststoff gefertigt, der einen hohen Anteil an einem elektrisch nicht leitenden, allerdings magnetisch leitenden Füller enthält.Corresponding a further general embodiment The invention has the winding and the magnetic poles forming machine element body Made of plastic, which has a high proportion of an electric contains non-conductive, but magnetically conductive filler.
Die elektrische Maschine gemäß der Erfindung erfüllt sämtliche Anforderungen an eine solche Maschine, nämlich hohe mechanische Festigkeit, insbesondere auch Schwingungs- und Stoßfestigkeit, vollständige elektrische Isolation gegenüber der Umgebung, vollständige elektrische Isolation der Befestigung der Maschine, vollständige elektrische Isolation der Antriebswelle, Explosionsschutz bei Betrieb in Umgebung mit Gefahrenstoffen, gesteigerte und wesentlich verbesserte Wärmeabfuhr für höhere Leistungsdichte, Integration der Leistungs- und Steuerelektronik in dem Gehäuse der Maschine.The electric machine according to the invention Fulfills all Requirements for such a machine, namely high mechanical strength, in particular also vibration and shock resistance, full electrical insulation opposite the environment, complete electrical insulation of the attachment of the machine, complete electrical Isolation of the drive shaft, explosion protection when operating in environment with hazardous substances, increased and significantly improved heat dissipation for higher power density, Integration of the power and control electronics in the housing of the Machine.
Die Steuerung der erfindungsgemäßen Maschine erfolgt vorzugsweise durch schnellschaltende IGBT's. Das mit den Magnetpolen der Wicklung zusammenwirkende weitere Maschinenelement, d.h. bevorzugt der Rotor, ist vorzugsweise mit Permanentmagneten bestückt, so dass bei vereinfachtem Aufbau auch die hohe Leistungsdichte erreicht wird.The Control of the machine according to the invention is preferably done by fast switching IGBT's. That with the magnetic poles the winding cooperating further machine element, i. prefers the rotor, is preferably equipped with permanent magnets, so that with a simplified construction also reaches the high power density becomes.
