Aufgrund der geringen Energiedichte verfügbarer Akkumulatoren müssen Elektrofahrzeuge auf geringen Energieverbrauch ausgelegt werden, um befriedigende Reichweiten bei vertretbaren Akkumulatorkosten zu gewährleisten. Wie das gesamte Fahrzeug sollte daher auch der An triebsstrang möglichst leicht und trotzdem hocheffizient sein. Durch die Integration von Elektromotoren in die Fahrzeugräder wird das Gewicht der zur Kraftübertragung notwendigen Komponenten, z. B. der Antriebswelle, eingespart und im Fahrzeuginneren entsteht zusätzlicher Nutzraum. Im Fahrzeugrad ist der für den Elektromotor verfügbare Raum jedoch eingeschränkt und insbesondere bei höheren Geschwindigkeiten sollten die ungedämpften Massen für ein günstiges Fahrverhalten gering sein, wodurch die Forderung nach einer hohen Leistungsdichte für den Radnabenantrieb weiter verstärkt wird.Due to the low energy density of available batteries, electric vehicles have to Low energy consumption can be designed to achieve satisfactory ranges with reasonable To ensure battery costs. Like the entire vehicle, the To powertrain as light as possible and yet highly efficient. By integrating Electric motors in the vehicle wheels becomes the weight of those necessary for power transmission Components, e.g. B. the drive shaft, saved and created in the vehicle interior Usable space. However, the space available for the electric motor in the vehicle wheel is limited and especially at higher speeds, the undamped masses should be for one Favorable driving behavior be low, which creates the demand for a high power density for the wheel hub drive is further reinforced.
Zur Einsparung der Getriebeverluste und des Getriebegewichts wurden bereits Anfang des 20. Jahrhunderts im Rad integrierte Direktantriebe eingesetzt.To save gearbox losses and gearbox weight, Century direct drives integrated in the wheel.
Aus der DE-PS 2 37 733 ist ein im Rad integrierter Direktantrieb für Elektrofahrzeuge bekannt, wobei der Elektromotor, der sich durch eine besondere Lagerung auszeichnet, aufgrund des Gewichts der elektrischen Erregerpole und des mechanischen Kommutators eine geringe Leistungsdichte aufweist.From DE-PS 2 37 733 is a direct drive integrated in the wheel for electric vehicles known, the electric motor, which is characterized by a special storage, due to a low weight of the electrical excitation poles and the mechanical commutator Has power density.
In der EP 0052344 A2 wird ein elektrisch kommutierter Permanentmagnetmotor beschrieben, dessen Magnete direkt an der Innenwandung des Felgenbodens angebracht sind. Der Stator sitzt auf einer massiven Statorscheibe, an deren Stirnfläche eine Schalteinrichtung angebracht ist. Der Elektromotor, der sich durch seine elektronische Steuerung auszeichnet, eignet aufgrund seiner beschränkten Leistungsdichte nur zum Antreiben langsamer oder leichter Kraftfahrzeuge mit geringem Leistungsbedarf.EP 0052344 A2 describes an electrically commutated permanent magnet motor, whose magnets are attached directly to the inner wall of the rim base. The stator is seated on a solid stator disc, on the end face of which a switching device is attached. Of the Electric motor, which is characterized by its electronic control, is suitable due to its limited power density only for driving slow or light vehicles low power requirement.
Der Erfindung liegt daher die Aufgabe zugrunde einen Elektromotor gemäß dem Oberbegriff des Anspruch 1 derart weiterzubilden, daß die Leistungsdichte gesteigert, eine ausreichende Wärmeabführung gewährleistet und das Felgenvolumen effektiv ausgenutzt wird.The invention is therefore based on the object of an electric motor according to the preamble of claim 1 in such a way that the power density increases, a sufficient Guarantees heat dissipation and the rim volume is used effectively.
Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst, vorteilhafte Ausgestaltungen sind in den Unteransprüchen enthalten. The object is achieved by the characterizing features of claim 1 solved, advantageous embodiments are included in the subclaims.
Die Leistungsdichte eines permaneterregten, hochpoligen und elektrisch kommutierten Radna bendirektantriebs wird somit gesteigert, indem der ringförmige Stator ein genutetes Blechpaket mit mehreren Nuten pro Polteilung aufweist. Die Nuten nehmen als Nutstäbe ausgebildete Leiter auf und für die Wärmeableitung aus dem genuteten Ständerblechpaket ist ein hülsen förmiger Kühlkörper vorgesehen, auf dem das Ständerblechpaket angeordnet ist. Gleichzeitig dient der Kühlkörper auch zur Kühlung der Kommutierungstransistoren, die an der Innenseite des Kühlkörpers angeordnet sind. Die Wärmeableitung aus dem Kühlkörper erfolgt durch Luft, die durch in den Motorschilden angebrachte Schlitze zum Kühlkörper geführt wird. Zusätzlich fungiert der Kühlkörper als Träger des Motors. Diese Funktionskombination trägt zur Gewichts ersparnis bei. Weiterhin ergeben sich aufgrund der kurzen Stromzuleitungen auch günstige elektrische Eigenschaften.The power density of a permanently excited, multi-pole and electrically commutated Radna Direct drive is thus increased by the annular stator being a grooved laminated core with several slots per pole pitch. The grooves take the form of groove rods Conductor on and for heat dissipation from the grooved stator core is a sleeve Shaped heat sink is provided on which the stator core is arranged. At the same time The heat sink also serves to cool the commutation transistors on the inside of the heat sink are arranged. The heat dissipation from the heat sink takes place through air, which is led to the heat sink through slots in the motor shields. In addition the heat sink acts as the support for the motor. This combination of functions adds weight saving on. Furthermore, due to the short power supply lines there are also cheap ones Electrical Properties.
Vorteilhafte Ausgestaltungen zeichnen sich dadurch aus, daß die Rückschlußdicke durch mindestens zwanzig Polpaare gering gehalten wird. Das Ständerblechpaket weist pro Polteilung eine ganzzahlige Anzahl von Nuten auf, wobei eine Beeinträchtigung durch die Polfühligkeit vermieden wird, indem die Pollückenbreite dem Verhältnis von Umfang des Luftspaltes zur Gesamtnutzahl entspricht. Pro Polteilung sind vorzugsweise vier bis sechs Nuten vorzusehen. Weiterhin wird die Nuttiefe derart gestaltet, daß sie in etwa der Summe aus Magnethöhe und der zweifachen Rückschlußdicke entspricht. Der Nutraum wird vorzugsweise durch drei bis neun Nutstäbe ausgenutzt, deren Breite der Nutbreite entspricht.Advantageous configurations are characterized in that the yoke thickness is characterized by at least twenty pole pairs are kept low. The stator core package has one pole pitch an integer number of slots, with an impairment due to pole sensitivity is avoided by the pole gap width the ratio of the circumference of the air gap to Total usable number corresponds. Four to six slots should preferably be provided per pole pitch. Furthermore, the groove depth is designed such that it is approximately the sum of the magnet height and corresponds to twice the inference thickness. The groove space is preferably three to nine slot bars are used, the width of which corresponds to the slot width.
Für kurze Verbindungswege und eine gute Raumausnutzung bestehen die Wickelköpfe aus scheibenförmigen Segmenten, wobei mehrere derartige Segmente zu einem scheibenförmigen Ring zusammengefaßt sein können.The winding heads are made of short connection paths and good use of space disc-shaped segments, with several such segments forming a disc-shaped Ring can be summarized.
Die Zeichnungen stellen vorteilhafte Ausführungsformen der Erfindung dar.The drawings represent advantageous embodiments of the invention.

In Fig. 1 geht die von links oben kommende Schwinge 1 in den Felgenkörper 2 über, um den die beiden Felgenhörner 3 rotieren, die wiederum zur Aufnahme des Reifens (nicht dargestellt) dienen. Im Felgenkörper 2 befindet sich ein Hohlraum 4 zur Aufnahme der elektrischen Kom mutierungseinrichtung und an seinem Außenumfang sind Stromverteilerplatten 5 angeordnet, die durch die Kommutierungstransistoren 6 mit den Stromversorgungsleitern 7 verbunden sind. Die Stromverteilerplatten 5 ermöglichen über an dem Kühlkörper 8 vorbei geführte Zu- und Ableitungen 9 für die Wickelkopfscheiben 10 die Stromversorgung des Motors. Zwischen den Wickelkopfscheiben 10 befindet sich das Ständerblechpaket 11, das Nuten zur Aufnahme der als Nutstäbe ausgebildeten Leiter aufweist.In Fig. 1, the rocker 1 coming from the top left merges into the rim body 2 , around which the two rim flanges 3 rotate, which in turn serve to receive the tire (not shown). In the rim body 2 there is a cavity 4 for receiving the electrical mutation device and on its outer circumference there are current distribution plates 5 which are connected by the commutation transistors 6 to the power supply conductors 7 . The power distribution plates 5 enable the motor to be supplied with power via supply and discharge lines 9 for the end windings 10 which are guided past the heat sink 8 . Between the winding head disks 10 is the stator core 11 , which has grooves for receiving the conductors designed as slot bars.
Der Rückschluß des Ständerblechpakets 11 ist mit 11a bezeichnet; der magnetische Rück schluß 13a des insgesamt mit 13 bezeichneten Rotors weist Magnetsegmente 14 auf, die durch einen Luftspalt 12 von dem Ständerblechpaket 11 getrennt sind. Die Lagerung des gesamten Motors erfolgt durch in den Felgenhörnern angeordnete Rollenlager 15, 16.The inference of the stator core 11 is designated 11 a; the magnetic return circuit 13 a of the rotor generally designated 13 has magnetic segments 14 which are separated by an air gap 12 from the stator core 11 . The entire motor is supported by roller bearings 15 , 16 arranged in the rim flanges.
Der Aufbau der Motoren gemäß Fig. 2 und Fig. 3 entspricht in den wesentlichen Elementen dem in Fig. 1 in der Felge angeordneten Motor. Zur Abdichtung des Luftspaltes 12 sind hier lediglich zwischen Motor und Felgenhörnern 3 Simmerringe 17 angeordnet, um eine Ver schmutzung zu verhindern.The structure of the motors in accordance with Fig. 2 and Fig. 3 corresponds to the disposed in Fig. 1 in the rim engine in the essential elements. To seal the air gap 12 3 Simmerrings 17 are only arranged here between the motor and rim flanges to prevent contamination.
Die in Fig. 4 dargestellten Segmente besitzen fünf Nuten 18, 19, 20, 21, 22 pro Polteilung und vier Nutstäbe 23, 24, 25 und 26 pro Nut. Bei einem Verhältnis von Polpaarzahl zu Anschluß klemmenzahl von zwei ergeben sich innerhalb des vier Polteilungen umfassenden Ausschnitts zwei Anschlußelementhälften 27, 28. Während bei lediglich einem Nutstab pro Nut die Ver bindung ausschließlich durch Verbindungselemente 30 erfolgt, kommen bei mehreren Nutstäben pro Nut Schleifenelemente 29 zum Einsatz.The segments shown in Fig. 4 have five slots 18 , 19 , 20 , 21 , 22 per pole pitch and four slot bars 23 , 24 , 25 and 26 per slot. Given a ratio of the number of pole pairs to the number of terminals, two connecting element halves 27 , 28 result within the cutout comprising four pole divisions. While with only one slot bar per slot, the connection is made exclusively by connecting elements 30 , loop elements 29 are used with several slot bars per slot.
Bezogen auf Fig. 4 bedeutet dies, daß zunächst die Nutstäbe 23-26 der Nut 18 mit denen der Nut 18′ verbunden werden; sind alle Nutstäbe dieser Nuten miteinander verbunden, erfolgt durch ein Verbindungselement 30 der Übergang zu Nut 18′′, deren Nutstäbe 23-26 mit denen der Nut 18′′′ verbunden werden.Based on Fig. 4, this means that first the slot bars 23-26 of the groove 18 are connected to those of the groove 18 '; are all slot rods of these grooves connected to each other, is made by a connecting element 30, the transition to groove 18 '', the slot bars 23-26 with which the groove 18 '''are connected.
Hieraus folgt, daß auf einer Seite des Ständerblechpakets 11 lediglich Schleifenelemente, deren Anzahl der Leiterbahnen im Steg der Nutstabanzahl entspricht und auf der anderen Seite Schleifenelemente zwischen Verbindungselementen bzw. Anschlußelementen auftreten, deren Anzahl der Leiterbahnen im Steg der Nutstabanzahl pro Nut minus eins entspricht. Eine Leiterbahn stellt hierbei die Verbindung zwischen zwei Nutstäben dar. It follows from this that on one side of the stator core 11 there are only loop elements, the number of conductor tracks in the web of which corresponds to the number of slot bars and, on the other side, loop elements occur between connecting elements or connecting elements, the number of conductor tracks in the web corresponds to the number of slot bars per slot minus one. A conductor track represents the connection between two slot bars.
Aus der Fig. 5a, 5b ergibt sich im einzelnen die Verbindung der Nutstäbe von zwei Nuten unterschiedlicher Polteilungen mit Hilfe eines Schleifenelementpaares. Das Schleifenelement (Fig. 5b) ist Bestandteil eines Segmentes; das andere Schleifenelement (Fig. 5a) bildet ein eigenständiges Segment. Das in Fig. 5a, 5b gezeigte Schleifenelementenpaar verbindet zwei Nuten mit jeweils vier Nutstäbe miteinander, die mit I-VIII bezeichnet sind. Die Stromzulei tungen sind hierbei mit 31 und 32 bezeichnet; durch die Zuleitung 31 erhält der Nutstab I von einem vorgelagerten Anschlußelement seinen Strom. Auf der anderen Seite des Ständerblechpa kets (nicht dargestellt) wird der Strom im anderen Schleifenelement (Fig. 5a) zum Nutstab II geführt, der wiederum im ersten Schleifenelement (Fig. 5b) mit dem Nutstab III verbunden ist, usw.From Fig. 5a, 5b, the compound of the slot bars of two grooves results in the individual different pole pitches by means of a loop element pair. The loop element ( Fig. 5b) is part of a segment; the other loop element ( Fig. 5a) forms an independent segment. The pair of loop elements shown in FIGS . 5a, 5b connects two grooves, each with four groove rods, which are designated by I-VIII. The Stromzulei lines are designated 31 and 32 ; Through the lead 31 , the grooved rod I receives its current from an upstream connection element. On the other side of the Ständerblechpa kets (not shown), the current in the other loop element ( Fig. 5a) is led to the slot bar II, which in turn is connected to the slot bar III in the first loop element ( Fig. 5b), etc.
Fig. 6 zeigt einen Ausschnitt des Motors im Querschnitt. In die zwischen den Magnetseg menten 14 vorhandenen Pollücken 34 werden diamagnetische Elemente 33 eingelegt, um den Streufluß zu vermindern. Fig. 6 shows a section of the engine in cross section. In the existing between the Magnetseg elements 14 pole gaps 34 diamagnetic elements 33 are inserted to reduce the leakage flux.
