Description
Zweiphasenwicklung für .1Vlaschinen mit Drahtwicklung, bei denen die Anzahl Nuten pro Pol und Phase eine ganze Zahl-+ 112 ist. -Bei der Verwendung. eines für eine dreiphasige Wicklung bestimmten Blechkernes für eine Zweiphasenwicklung ergaben sich bisher verschiedene Schwierigkeiten. Man war entweder genötigt, einzelne Nuten unbewickelt zu lassen oder man war in der Drahtzahl insofern beschränkt, als man nur eine durch q. teilbare Drahtzahl in jeder Nut anordnen muBte gemäß dem- Wickelschema 1/4 1/4 1/4 1 1 1 ]: 94 (1. Phase.) 3/4 3/4 1 11 3/4 (z. Phase.) Gemäß der Erfindung wird man für zweiphasige Maschinen mit Drahtwicklung unabhängig in der Wahl der Nut und erhält eine gleichmäßig -fortschreitende Wicklung, stinkrechte Lage der Feldvektoren und ein gleichmäßiges Moment, ,wenn man jede Lochspule mit der halben Drahtzahl pro Nut wickelt und den Wickelschritt jeder Lochspule jeweils um »r« größer wählt als den Schritt der vorhei gewickelten Lochspule dergleichen Spulengruppe. Bei n-Polen liegen dann in n-Nuten Drähte der beiden Phasen nebeneinander, die besonders sorgfältig zu isolieren sind. Die Fig. x zeigt ein Beispiel der Anordnung für einen vierpoligen Motor mit 28 Nuten. Die Zahl der Nuten ist also in diesem Falle 31/2 pro Pol und Phase. . In jeder Nut liegen zwei halbe Lochspulen. Die Wicklungsanfänge der beiden Phasen sind mit u, v, der Verkettungspunkt mit x, y bezeichnet. In. . den - Nuten a, b, c, d liegen Drähte der beiden Phasen nebeneinander. ' Die Fig. 2 stellt die =bisher übliche Wicklungsart, Fig.3 die neue Wicklungsart für zweiphasige Maschinen mit Drahtwicklung dar. Eine Wicklung, @ bei der der Wickelschritt nebeneinanderliegender Windungen der Spulen sich um = unterscheidet; ist für Stabwicklungen mit je einem' Stab in der Unter- und Oberlage der Nut bekannt, jedoch nur für den Fall, daB pro Pol und Phase eine ganze Zahl Nuten vorhanden ist.Two-phase winding for .1 machines with wire winding, in which the number of slots per pole and phase is an integer - + 112. -When using. a sheet metal core intended for a three-phase winding for a two-phase winding, various difficulties have arisen up to now. One was either obliged to leave individual grooves unwound or one was limited in the number of wires insofar as one could only use one through q. Arrange the divisible number of wires in each groove according to the winding scheme 1/4 1/4 1/4 1 1 1 ]: 94 (1st phase.) 3/4 3/4 1 11 3/4 (z. Phase.) According to the invention, for two-phase machines with wire winding one becomes independent in the choice of the slot and one obtains a steady-progressive winding, perfectly vertical position of the field vectors and a steady moment, , if you wind each perforated coil with half the number of wires per slot and choose the winding pitch of each perforated coil to be "r" larger than the pitch of the previously wound perforated coil of the same coil group. In the case of n-poles, wires of the two phases lie next to each other in n-slots and must be insulated with particular care. Fig. X shows an example of the arrangement for a four-pole motor with 28 slots. The number of slots in this case is therefore 31/2 per pole and phase. . There are two half-hole coils in each groove. The winding starts of the two phases are marked u, v, and the interlinking point is marked x, y. In. . the - slots a, b, c, d are wires of the two phases next to each other. FIG. 2 shows the previously usual type of winding, FIG. 3 the new type of winding for two-phase machines with wire winding. A winding in which the winding pitch of adjacent turns of the coils differs by =; is known for bar windings with one bar each in the lower and upper layers of the slot, but only for the case that there is an integer number of slots per pole and phase.
