Description

Elektrisch betriebene Zentrifuge für hohe Drehzahlen Die Erfindung betrifft eine elektrisch betriebene Zentrifuge für hohe Drehzahlen. Es ist bereits vorgeschlagen worden, die Betriebsdrehzahlen der Zentrifuge durch eine elektrische Bremsung des Antriebs zu vermindern und bis zum Stillstand herabzusetzen, wobei die frei werdende kinetische Energie in elektrische Energie verwandelt und anschließend durch Widerstände vernichtet wird. Dabei ist zur Kontrolle der Belastung des Antriebsmotors in dessen Stromkreis eine Glühlampe eingeschaltet, deren Helligkeit die Belastung des Antriebsmotors anzeigt.Electrically operated centrifuge for high speeds The invention relates to an electrically operated centrifuge for high speeds. It is already has been proposed to control the operating speeds of the centrifuge by an electric Reduce braking of the drive and reduce it to a standstill, whereby the released kinetic energy is converted into electrical energy and then is destroyed by resistance. It is used to control the load on the drive motor an incandescent lamp switched on in its circuit, its brightness the load of the drive motor.

Die Erfindung ist darin zu sehen, daß im Augenblick der höchstzulässigen Belastung des Antriebsmotors eine Relaisschaltung die elektrische Ab-Bremsung des Antriebsmotors auslöst. Der Antrieb wird auf Leerlauf oder Bremsung geschaltet.The invention is to be seen in the fact that at the moment the highest permissible Load of the drive motor a relay circuit, the electrical braking of the Drive motor triggers. The drive is switched to idling or braking.

An sich ist eine selbsttätige Steuerung von Getriebekupplungen von Elektromotoren bekannt. Dabei erfolgt aber bei dieser bekannten Ausbildung keine elektrische Abbremsung. Das Abbremsen erfolgt vielmehr über ein Bremsgetriebe mit Bremstrommel und Bremsband. Derartige mechanische Antriebe sind nicht Gegenstand der Erfindung, die im Gegensatz dazu mit einer rein elektrisch wirkenden Bremse arbeitet.In itself is an automatic control of gear clutches from Known electric motors. In this known training, however, none takes place electrical braking. Rather, braking takes place via a brake gear Brake drum and brake band. Such mechanical drives are not the subject of the invention, in contrast with a purely electrically acting brake is working.
