Bei Elektromotoren für Fahrzwecke hat man bisher beim Anlassen und beim Regeln der Geschwindigkeit entweder die Spannung des Leitungsnetzes bezw. der Stromquelle mehr oder weniger abgedrosselt, indem man mehr oder weniger Widerstand vorschaltete, oder man führt eine Verstärkung des Magnetfeldes durch geeignete Umschaltung der gruppenweise angeordneten Magnetwickelungen herbei, welche alsdann aus zwei oder mehr Kupferspulen besteht.In the case of electric motors for driving purposes, starting and controlling the Speed either the voltage of the line network respectively. the power source more or less throttled by adding more or less resistance, or the magnetic field is strengthened by suitable switching of the groups arranged magnet windings, which then consist of two or more copper coils consists.
Bei der ersten Art entsteht der Nachtheil, dafs eine erhebliche Menge Arbeit verloren geht; aufserdem aber ist bei ihr ein besonderer Widerstandskasten nöthig, welcher wegen des für ihn erforderlichen Raumes namentlich bei Selbstfahrern störend wirkt.The disadvantage of the first type is that a considerable amount of work is lost goes; In addition, however, a special box of resistance is necessary for her, which because of the the space required for him is particularly disturbing for self-propelled vehicles.
Das an zweiter Stelle genannte Verfahren erfordert eine unverhä'ltnifsmäfsig grofse Menge todter Kupferdrahtwindungen auf den Magnetschenkeln, damit zu hohe Erwärmung verhütet wird.The process mentioned in the second place requires a disproportionately large amount Dead copper wire windings on the magnet legs to prevent excessive heating will.
Den Gegenstand der vorliegenden Erfindung bildet eine Vorrichtung zum Anlassen und Regeln von Elektromotoren, bei der es eines besonderen Anlafsvviderstandes nicht bedarf. Dabei ergeben sich noch die weiteren Vortheile, dafs in solchen Fallen, in welchen Sammler die Stromquelle bilden, diese zu verschiedenen Gruppen geschaltet werden können, und bei Betrieb mittelst mehrerer Motoren für diese verschiedene Schaltungen ermöglicht sind.The subject of the present invention forms a device for tempering and Control of electric motors that do not require a special starting resistor. Included there are still further advantages, that in such cases, in which collector form the power source, these can be switched to different groups, and at Operation by means of several motors for these different circuits are possible.
In der Zeichnung ist diese Vorrichtung an dem Schema eines Hauptstrommotors veranschaulicht. Sie besteht darin, dafs neben den dem Betrieb dienenden kupfernen Magnetschenkelerregerspulen α noch besondere Erregerspulen b c . . . so angeordnet sind, dafs sie mit Hülfe des Fahrschalters d einzeln oder zusammen in Hintereinanderschaltung mit der Erregerspule α gebracht werden können, und dafs für diese besonderen Erregerspulen ein Material Anwendung findet, welches einen gröfseren elektrischen Widerstand hat als Kupfer, z. B. Eisen.In the drawing, this device is illustrated using the scheme of a main current motor. It consists in the fact that, in addition to the copper magnetic leg exciter coils α used for operation, there are also special exciter coils bc. . . are arranged so that they can be brought into series connection with the excitation coil α individually or together with the aid of the drive switch d, and that a material is used for these special excitation coils which has a greater electrical resistance than copper, e.g. B. iron.
Angenommen, die Stromquelle ist eine Sammlerbatterie e. so ergiebt sich die Wirkung der Vorrichtung aus dem Schema, in welchem d eine Abwickelung der Walze des Fahrschalters und f den Anker bedeutet, wenn die drei Magnetspulen a, b und c, wie dargestellt, hinter einander geschaltet sind, wie folgt:Assume the power source is a collector battery e. The effect of the device results from the scheme in which d means the unwinding of the drive switch's roller and f means the armature, when the three magnetic coils a, b and c are connected one behind the other as shown, as follows:
Bei der Stellung I des Fahrschalters mufs der Strom durch alle drei Erregerspulen a, b und c hindurchgehen. Demzufolge findet die stärkste Erregung des Magnetfeldes statt, infolge deren der Motor seinen langsamsten Gang macht. Hierbei macht sich der verhältnifsmäfsig grofse Widerstand der beiden Eisenspulen b und c seinerseits noch in einer weiteren Herabminderung der Motorgeschwindigkeit geltend, weil dadurch ein gewisser Spannungsabfall entsteht. Bei der Stellung II des Fahrschalters ist nur noch die Eisenspule b hinter die Kupferspule α geschaltet und daher die Geschwindigkeit des Motors eine gröfsere. Am gröfsten aber ist dieselbe in der Stellung III des Fahrschalters, in der nur die Kupferspule a in Wirkung ist.When the drive switch is in position I, the current must pass through all three excitation coils a, b and c . As a result, the strongest excitation of the magnetic field takes place, as a result of which the motor makes its slowest gear. Here the comparatively great resistance of the two iron coils b and c is in turn expressed in a further reduction in the motor speed, because this results in a certain drop in voltage. When the drive switch is in position II, only the iron coil b is connected behind the copper coil α and therefore the speed of the motor is greater. But it is greatest in position III of the drive switch, in which only the copper coil a is in effect.
Bei den Stellungen IV, V und VI des Fahrschalters sind die Vorgänge dieselben, nur sind dann die Accumulatoren, welche vorher inIn positions IV, V and VI of the drive switch, the processes are the same, only are then the accumulators, which were previously in
zwei Abtheilungen parallel geschaltet waren, alle hinter einander geschaltet.two departments were connected in parallel, all connected one behind the other.
