Description
Torrichtung zum Einstellen der Drehzahl bei Scheibenwischenaotoren mit PermanentmagnetenDoor direction for setting the speed at Windshield wiper motors with permanent magnets
Die Erfindung befaßt sich mit einer Torrichtung zum Einstellen der Drehzahl bei Scheibenwisehermotoren mit Permanentmagneten, mit deren Hilfe durch Gegenmagaetisierung die gewünschte Soll-Drehzahl eingestellt werden kann«The invention is concerned with a gate device for adjusting the speed of windshield wiper motors with permanent magnets, with the help of which the desired Target speed can be set «
Die magnetische Kraft der Permanentmagnete liegt auch bei gleichmäßiger Magnetisierung in einem Streubereich von ca. - 7 Ί»* Diese Streuung wirkt sich bei den Motoren-Kenndaten entsprechend aus. Die Permanentmagnete werden bei der Herstellung so bemessen, daß bei der unteren Toleranz die geforderten Kenndaten des Motors erreicht werden·Even with uniform magnetization, the magnetic force of the permanent magnets lies in a range of approx. - 7 Ί »* This spread has a corresponding effect on the motor characteristics. The permanent magnets are dimensioned during manufacture so that the required motor characteristics are achieved with the lower tolerance
Die durch die Erfindung vorgeschlagene Vorrichtung die aus einem zum Aufsetzen auf die Polhömer des Scheibenwischermotors geeigneten Eisenkern mit Magnetspule, aua einem Schalter und aus einem geeichten einstellbaren Wideratand besteht, ermöglicht durch Gegenmagnetisierung des_Pexmanentmagneten eine Einstellung der Motore auf gleiche Kenndaten. Uach erfolgter Messung des Drehmomentes und der Drehzahl wird am geeichten und einstellbaren Widerstand ein entsprechender Wert eingestellt, der die Intensität der Gegenmagnetisierung beim Schließen des Schalters regelt.The proposed by the invention device which consists of a for placement on the Suitable pole hanger of the windshield wiper motor Iron core with magnetic coil, also a switch and a calibrated adjustable resistor exists, enables an adjustment by counter-magnetizing the_Pexmanentmagneten the motors have the same characteristics. After the torque and speed have been measured a corresponding value is set on the calibrated and adjustable resistor, which the Controls the intensity of the counter magnetization when the switch is closed.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargelegt»In the drawing, an embodiment of the invention is shown »
Pigur 1 zeigt die Vorrichtung die an einem Wischermotor angelegt ist·Pigur 1 shows the device applied to a wiper motor
Die Stromapule ist an den Klemmen 1 und 2 angeschlossen. Von der Klejame 1 führt eine Leitung zur Spule 3, die auf den Eisenkern 4 aufgewickelt ist. Das andere Ende der Spule 5 führt über den Schalter 5 zum geeichten und einstellbaren Widerstand 6. 33er Abgriff 7 deeThe Stromapule is connected to terminals 1 and 2. A line leads from Klejame 1 to the coil 3, which is wound onto the iron core 4. The other end of the spool 5 leads via switch 5 to the calibrated and adjustable resistor 6. 33 tap 7 dee
Widerstandes ist mit der Klemme 2 leitend verbunden. Der Eisenkern 4 ist so ausgebildet, daß die beiden Pole dieses Eisenkernes 401 und 402 den Polhörnern 8 und 9 des !ischermotors 10 gegenüberliegen· Zwischen den Polhörnern 8 und 9 liegt der Permanentmagnet 11.Resistor is conductively connected to terminal 2. The iron core 4 is designed so that the two poles of this iron core 401 and 402 correspond to the pole horns 8 and 9 of the isher motor 10 opposite · The permanent magnet 11 is located between the pole horns 8 and 9.
Üfochdem die Kenndaten des Wischermotors festgestellt wurden, wird ein dem Ergebnis entsprechender Wert durch aen Schieber 7 auf den Widerstand 6 eingestellt. Durch 1AaS Betätigen des Schalters 5 wird durch einen Stromstoß die Gegenmagnetisierung des Permanentmagneten 11 durchgeführt. Damit wird erreicht, daß alle ^ischermotoren gleiche Kenndaten besitzen»Üfochdem the characteristics of the wiper motor are detected, a value corresponding to the result value is set by aen slider 7 on the resistor. 6 By actuating the switch 5 for 1 AaS, the counter-magnetization of the permanent magnet 11 is carried out by a current surge. This ensures that all ^ isher motors have the same characteristics »
