Claims (1)

**WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. zum Zwecke, der Stärke des magnetischen Feldes unter den in der Bürstenlinic liegenden Zacken einen'derartigen Verlauf zu geben, dass innerhalb eines bestimmten Geschwindigkeits- bereiches, d, h. von einer bestimmten Tourenzahl ab, die in der kurzgeschlossenen Läuferspule induzierten elektromotorischen Kräfte einander aufheben. ** WARNING ** End of CLMS field may overlap beginning of DESC **. for the purpose of giving the strength of the magnetic field beneath the prongs located in the brush line such a curve that within a certain speed range, i. e. from a certain number of revolutions, the electromotive forces induced in the short-circuited rotor coil cancel each other out. 2. Ausführungsforni einer Kommutierungseinrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Kompensationsspulen, welche Fortsätze der in der Kurzschlussbürsten- EMI4.1 linie liegende Punkte der Ständerwicklung, die jeweilen um eine Polteilung voneinander abstehen, direkt bzw. vermittelst eines regulierbaren Serientransformators angeschlossen sind. 2. Ausführungsforni a commutation device according to claim 1, characterized in that the compensation coils, which extensions of the in the short-circuit brush EMI4.1 Line-lying points of the stator winding, which each protrude from one another by one pole pitch, are connected directly or by means of an adjustable series transformer. 8. Ausführungsform einer Kommuticrungseinrichtung nach Anspruch I, gekennzeichnet durch kleine Ililfsspulen, welche die Fortsätze der in der Bürstenlinie liegenden Zacken u111schliessen und durch welche der Ständerstrom geleitet wird. 8. Embodiment of a commutation device according to claim I, characterized by small auxiliary coils which close the extensions of the prongs lying in the brush line and through which the stator current is passed.
