Description
<Desc/Clms Page number 1>
EMI1.1
Die Erfindung betrifft Induktionsmotoren, denen der Arbeitsstrom am Läufer zugeführt wird und bei denen aus einer Hilfswicklung im Läufer die zur Drehzahl- oder Phasenregelung erforderliche, z. B. durch Bürstenverschiebung oder durch Regelung eines Transformators beeinflussbare Spannung entnommen und der Ständerwicklung aufgedruckt wird. Die Hilfswicklung wird bei dieser Anordnung vom Ständerstrom durchflossen und erzeugt dadurch ein magnetisches Feld, das störende Wirkungen hervorruft. Es beeinflusst den Leistungsfaktor ungünstig und verstärkt bei Einphasenmotoren das inverse Drehfeld, wodurch die Kommutierung verschlechtert wird.
Nach der Erfindung sollen diese Störungen dadurch vermieden werden, dass die magnetisierende Wirkung der Hilfswicklung durch eine Kompensationswicklung im Ständer ganz oder zum Teil aufgehoben wird.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Diese zeigt einen läufergespeisten Drehstrominduktionsmotor mit dem Ständer s und dem Läufer A Der Läufer besitzt eine
EMI1.2
angeordnet, die die magnetisierende Wirkung der Hilfswicklung b auf dem Läufer kompensiert und damit die schädlichen Wirkungen dieser Wicklung verhindert.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

EMI1.1
The invention relates to induction motors to which the working current is supplied to the rotor and in which the required for speed or phase control, z. B. removed by brush displacement or by regulating a transformer voltage and the stator winding is printed. In this arrangement, the auxiliary winding is traversed by the stator current and thereby generates a magnetic field that causes disruptive effects. It has an unfavorable effect on the power factor and increases the inverse rotating field in single-phase motors, which worsens the commutation.
According to the invention, these disturbances are to be avoided in that the magnetizing effect of the auxiliary winding is completely or partially canceled by a compensation winding in the stator.
An embodiment of the invention is shown in the drawing. This shows a rotor-fed three-phase induction motor with stator s and rotor A. The rotor has a
EMI1.2
arranged, which compensates for the magnetizing effect of the auxiliary winding b on the rotor and thus prevents the harmful effects of this winding.
