Description

Elektromotor mit Drehzahlregelung durch fernbedienbare elektronische Phasenanschnittsteuerung Die Erfindung betrifft einen Elektromotor mit Drehzahlregelung bzw. -steuerung, die durch elektronische Phasenanschnittsteuerung erfolgt. Im allgemeinen weist eine solche Steuerung ein RC-Glied auf, und die Ladung des Kondensators erfolgt über einen von Hand veränderlichenWiderstand, mit dem der Phasenanschnittwinkel und damit die Motordrehzahl verändert wird. Es gibt nun Fälle, in denen die Bedienung der Steuerung über eine Fernleitung erfolgt, die nur eine Kleinspannung führen darf. Diesist beispielsweise bei Hauageräten und insbesondere wieder bei Staubsaugern der Fall, wobei etwa die Stahlspirale des Saugschlauches die Kleinspannungsleitung bilden kann.Electric motor with speed control by remote-controlled electronic Phase control The invention relates to an electric motor with speed control or control, which is carried out by electronic phase control. In general if such a control has an RC element, and the capacitor is charged via a manually variable resistance with which the phase control angle and thus the engine speed is changed. There are now cases where the operation the control takes place via a long-distance line that may only carry a low voltage. This is for example in the case of household appliances and especially again in the case of vacuum cleaners the case where, for example, the steel spiral of the suction hose is the extra-low voltage line can form.

Die Erfindung ermöglicht diese Forderung dadurch, daß zwischen das RC-Glied der Phasenanschnittsteuerung und die Fernbedienungsleitung zum Stellglied ein Transformator geschaltet ist, durch den das Stellglied mit seiner Leitung galvanisch vom Netz getrennt ist und über den die Ladung des RC-Glied.Kondensators erfolgt. Auf diese Weise liegt das von Hand zu bedienende Stellglied sowie seine Zuleitung nicht an der Netzspannung, sondern an einer für die Bedienungaperson ungefährlichen Kleinspannung.The invention enables this requirement in that between the RC element of the phase control and the remote control line to the actuator a transformer is connected through which the actuator with its line galvanically is disconnected from the mains and via which the RC element capacitor is charged. In this way, the actuator to be operated by hand and its supply line are located not to the mains voltage, but to something that is not dangerous for the operator Low voltage.

Die Erfindung ist an Hand der Zeichnung in einem Ausführungsbeispiel beschrieben.The invention is based on the drawing in one embodiment described.

In der Zeichnung sind mit 1 die Feldwicklungen und der Anker eines Elektromotors bezeichnet, während 2 des Schaltschema einer an sich bekannten elektronischen Phasenanschnittsteuerung für die Drehzahlstellung des Motors ist. Mit 3 ist eine Fernbedienungsleitung für die Steuerung bezeichhet, in die ein Stellglied 4 eingebaut ist. Zwischen dieser Leitung 3 und dem RC-Glied der Phasenanschnittsteuerung ist ein Sicherheitstransformator 5 geschaltet.In the drawing, 1 is the field windings and the armature one Electric motor referred to, while 2 of the circuit diagram of a known electronic Phase control for the speed setting of the motor is. With 3 there is one Remote control line for the control denotes, in which an actuator 4 is built is. The phase control is between this line 3 and the RC element a safety transformer 5 connected.

Verstellt man das Stellglied 4, dann ändert sich der in der Leitung 3 fließende Sekundärstrom, der wiederum den Primärstrom beeinflußt und das Laden des Kondensators 6 bewirkt.If the actuator 4 is adjusted, the one in the line changes 3 flowing secondary current, which in turn affects the primary current and the charging of the capacitor 6 causes.
