Description

Die Erfindung betrifft eine Einrichtung zum Anlassen von Synchronmotoren.The invention relates to a device for starting synchronous motors.

Die Einrichtung ist auf der Zeichnung schematisch dargestellt.The device is shown schematically in the drawing.

Der Motor ist mit 1 bezeichnet, 2 stellt die Motorwicklung dar, 3 eine zusätzliche, als Generatorwicklung bezeichnete Wicklung. Die Wicklungen 2 und 3 sind mit Bezug auf die Polteilung des Läufers gegeneinander räumlich in der Phase versetzt angeordnet. Wird der Motor irgendwie angestoßen, so wird in der Generatorwicklung 3 eine Wechselfrequenz induziert, die durch die Leitungen 27, 29 über den Verstärker 9 wieder auf die Motorwicklung zurückwirkt, so daß der Motor schließlich mit einer bestimmten Drehzahl läuft, die der Frequenz entspricht, auf die der aus der Sekundärwicklung des Transformators 6, der Wicklung 2 und dem Kondensator 7 bestehende Kreis abgestimmt ist. Ist der Motor nun an ein Netz 4, 4 bestimmter Frequenz angeschlossen und ist der Verstärkerkreis auf diese Frequenz abgestimmt, so beschleunigt sich der Motor bis auf dieThe motor is denoted by 1, 2 represents the motor winding, 3 an additional one, as Generator winding designated winding. Windings 2 and 3 are with reference to FIG the pole pitch of the rotor is spatially offset from one another in the phase. If the motor is triggered somehow, an alternating frequency is generated in the generator winding 3 induced, which acts back through the lines 27, 29 via the amplifier 9 again on the motor winding, so that the The engine eventually runs at a certain speed that corresponds to the frequency that of the secondary winding of the transformer 6, the winding 2 and the capacitor 7 existing circle is coordinated. If the motor is now connected to a network 4, 4 more specific Frequency is connected and the amplifier circuit is tuned to this frequency, so the engine accelerates up to that

dieser Frequenz entsprechende Drehzahl und 25 fällt selbsttätig in Synchronismus. Die der Wicklung 3 entnommenen, im Verstärker 9 verstärkten Impulse, deren Frequenz sich mit der Motordrehzahl erhöht, ergeben infolge der räumlichen Phasenverschiebung der Wick- 30 lungen 2 und 3 während der ganzen Anlaufperiode ein den Läufer beschleunigendes Drehmoment.speed corresponding to this frequency and 25 automatically falls into synchronism. The pulses taken from the winding 3 and amplified in the amplifier 9, the frequency of which increases with the engine speed, result in a torque accelerating the rotor during the entire start-up period due to the spatial phase shift of the windings 2 and 3.
