Description

Bei Mittel- 'und Hochfrequenzmaschinen der Gleichpoltype wird die HoehfrequenzwicHung in der Regel als Einlochwicklnng durchgebildet, 'um einen möglichst kleinen Durchmesser und damit geringe Luftreibungsverluste zu erhalten. Bei· derartigen Maschinen, läßt sich das bekannte Mittel, die einzelnen Zähne (Pole) an den Zahnflächen so zu formen, daß· eine sinusförmige Feldkurve entsteht, in den meisten Fällen nicht anwenden, da im Hinblick auf den geringen Luftspalt ein Nachschleifen, des ' Läufers zur richtigen Zentrierung erforderlich und deshalb eine derartig© Formgebung prak- *5 tisch, so gut wie ausgeschlossen ist. Infolgedessen erhalten die Felder etwa Trapezform, wodurch starlc ausgeprägte Oberwellen in der Spannung bedingt werden.In the case of medium and high frequency machines of the homopolar type, the high frequency weight is used usually formed as a single-hole winding, around the smallest possible diameter and thus to obtain low air friction losses. With machines of this type, allows the known means, the individual teeth (poles) on the tooth surfaces shape that · a sinusoidal field curve arises, in most cases not apply, because in view of the small air gap regrinding, des '' Rotor required for correct centering and therefore such a © shaping is * 5 table, is as good as impossible. Consequently the fields get approximately trapezoidal shape, which starlc pronounced harmonics in the Tension.

Um diesen Nachteil zu beheben, ist es bekanntgeworden, die einzelnen Zahnräder oder die zu diesen gehörigen Ständerwicklungsteile gegeneinander zu versetzen. Dies Mittel hat - aber noch den großen Nachteil, daß· durch das Versetzen die Lüftung der Maschine erheblich verschlechtert wird, da die die Maschine in axialer Richtung durchfließende Kühlluft aus ihrer Richtung stark abgelenkt wird.To remedy this disadvantage, it has become known, the individual gears or to offset the stator winding parts belonging to these against each other. This means has - but still the big disadvantage that · by moving the ventilation of the machine considerably is worsened because the cooling air flowing through the machine in the axial direction is greatly deflected from its direction will.

Nach der Erfindung soll dieser Nachteil dadurch behoben werden, daß die Maschine in der Umfangsrichtung in mehrere Teile zerlegt wird und diese Teile um einen der zu beseitigenden Oberwelle entsprechenden Winkel gegeneinander versetzt werden. DieUnterteilung kann entweder im Polrad oder im Ständer durchgeführt werden. Im letzten Falle kann die Ständerwicklung in mehrere Teile zerlegt werden, von denen jeder einen bestimmten Teil des Ständerumfanges zugeordnet erhält. Diese Teile werden dann um einen bestimmten Winkel gegeneinander versetzt, so wie früher die zu benachbarten Zahnrädern gehörigen Ständerwicklungsteile gegeneinander versetzt wurden.According to the invention, this disadvantage is to be eliminated in that the machine is divided into several parts in the circumferential direction and these parts around one of the to eliminating harmonic are offset against each other at the appropriate angle. The subdivision can be carried out either in the pole wheel or in the stator. In the latter case, the stator winding can be divided into several Parts are dismantled, each of which is assigned a specific part of the stand circumference receives. These parts are then offset from one another by a certain angle, just like the stator winding parts belonging to adjacent gears in the past were moved.

Ein Ausführungsbeispiel hierfür ist in Fig. 1 der Zeichnung dargestellt. Hierbei ist die Ständerwicklung in zwei Hälften 11 und 12 zerlegt, die 'um einen Winkelt gegeneinander versetzt sind. XJm- bei einer derartigen Anordnung einen unsymmetrischen magnetischen Zug des Ständers auf den Läufer zu vermeiden, werden; die beiden Hälften 11 und 12 nochmals in je zwei Gruppen unterteilt und diese Gruppen auf dem Umfang einander gegenübergelegt, wodurch sich eine Anordnung nach Fig. 2 ergibt. Die aus je zwei einander gegenüberliegenden Gruppen 11,11 bzw. 12, 12 bestehenden Wicklungshälften sind hier ebenfalls 'um den Winkelt gegeneinander versetzt, so daß eine Unterdrückung der entsprechenden Oberwelle erfolgt. Es ist auch möglich, die Ständerwicklung in mehr als zwei Teile aufzuteilen und die zu diesen Teilen: gehörenden, einander gegenüberliegenden Gruppen um verschiedene Winkel gegeneinander zu versetzen, wodurch mehrere Oberwellen unterdrückt werden.An exemplary embodiment for this is shown in FIG. 1 of the drawing. Here, the stator winding is divided into two halves 11 and 12 which are offset from one another by an angle. XJm - to avoid an asymmetrical magnetic pull of the stator on the rotor with such an arrangement; the two halves 11 and 12 are again divided into two groups and these groups are placed opposite one another on the circumference, resulting in an arrangement according to FIG. Consisting of two opposing groups 11, 1 1, 12, 12 existing winding halves are also offset from each other here 'to the Angles, so that a corresponding suppression of harmonics is performed. It is also possible to divide the stator winding into more than two parts and to offset the opposing groups belonging to these parts by different angles from one another, whereby several harmonics are suppressed.
