Der Repulsionsmotor besitzt den Nachteil, eine nicht stabile Wirkungsweise zu haben oder mit verschiedenen Anwendungen, z. B. als Werkstattsmotor, unvereinbar zu sein. Große Veränderungen in der Belastung ziehen tatsächlich für diesen Motor große Veränderungen in der Geschwindigkeit nach sich.The repulsion motor has the disadvantage of having an unstable operation or with various applications, e.g. B. as a workshop engine to be incompatible. Big changes in load actually pull big changes for this engine in speed after itself.
Andererseits besitzt der kompensierte Nebenschluß-Kommutatormotor einen hohen Leistungsfaktor, läuft aber nicht ohne weiteres unter Belastung an. Man kann nun die Vorteile beider Motoren vereinigen, wenn man den Motor als Repulsionsmotor anlaufen läßt und ihn dann in einen kompensierten Nebenschlußmotor umwandelt.On the other hand, the compensated shunt commutator motor has a high Power factor, but does not start easily under load. You can now see the benefits Both motors combine if the motor is started up as a repulsion motor and then converted into a compensated shunt motor converts.
Besonders wertvoll ist diese UmwandlungThis transformation is particularly valuable
bei Repulsionsmotoren mit Kurzschlußsehnen.in repulsion motors with short-circuit tendons.
Für die Umwandlung solcher Motoren läßtLets for the conversion of such engines
man nach dem Anlauf zwischen den die Bürsten cl, d1 und c2, d2 verbindenden Kurzschlüssen al und a1 des Läufers r in dem Stromkreis g eine elektromotorische Kraft wirken, welche imstande ist, die Erregung des Feldes des Motors im Läufer hervorzurufen. Man wird eine elektromotorische Kraft von einer Phase erhalten, welche für diese Erregung geeignet ist, wenn man sie einer Hilfswicklung, die auf dem Ständer s eine passende Lage hat, oder Hilfsklemmen des Ständers e1, fl unmittelbar oder über einen Transformator entnimmt, welche allgemein mit Bezug auf die Hauptklemmen e, f verschoben sind.after the start-up between the short-circuits a l and a 1 of the rotor r connecting the brushes c l , d 1 and c 2 , d 2 , an electromotive force acts in the circuit g , which is capable of exciting the field of the motor in the rotor to evoke. One will receive an electromotive force of a phase which is suitable for this excitation when they are an auxiliary winding S has on the stator a suitable location, or auxiliary terminals of the stator e 1, f l directly or extracts via a transformer which are generally shifted with respect to the main terminals e, f.
Bei dem in der Figur dargestellten Beispiel erfolgt die Umwandlung lediglich durch Schließen des Schalters Z. Dann liegen die Kurzschluß verbindungen a1, a1 an der Sekundärwicklung ί2 eines Transformators, dessen Primärwicklung tl an die Klemmen e1,/1 der Ständerwicklung 5 angeschlossen ist.In the example shown in the figure, the conversion takes place only by closing the switch Z. Then the short-circuit connections a 1 , a 1 are on the secondary winding ί 2 of a transformer, whose primary winding t l to the terminals e 1 , / 1 of the stator winding 5 connected.
