Description

Kollektorlose gleichstrommaschine Die herkömmliche Gleichstrommaschine mit Kollektor hat eine Reihe von Mängeln, die sich durch Anwendung elektronischer Schalter vermeiden lassen. Als angel muß man den Kollektor mit den Bürsten, die sehr schwierige und aufwendige Konstruktion des Rotors und die umlaufende Arbeitswicklung wegen der Drehzahlbegrenzung mit RUcksicht auf die Zentrifugalkräfte bezeichnen.Brushless DC machine The conventional DC machine with collector has a number of shortcomings, which can be seen by applying electronic Avoid switches. As an angel you have to brush the collector with the very difficult and complex construction of the rotor and the circumferential working winding because of the speed limitation with consideration of the centrifugal forces.

Erfindungsgemäß soll der Kollektor durch elektronische Schalter ersetzt werden und die in stich geschloßene Xrommelankerwicklung als Doppel- oder Mahrfachwicklung ausgeführt werden. Die Mehrfachwicklung soll beim Lauf die Unterbrechung der Stromzufuhr und damit das Auftreten höherer Öffnungsspannungen verhindern, welche leicht zu Zerstörung der elektronischen Schalter führen. Zu dem vereinfacht sich der Schaltungstechnische Aufwand erheblich, weil die Löschung bei Verwendung yon Thyristoren sehr einfach wird, und die Freiwerdezeit so groß ist, daß -es niemals zu Kurzschlußvorgängen beim Antiparallelbetrieb der einzelnen Wicklung gruppen kommen kann. Die Heratellung der Doppel oder Mehrfachwicklung ist dabei sehr einfach, da sie als zwei- oder mehrdrähtige Wicklung hergestellt werden kann und keine besonderen Isolationsmaßnahmen erforderlioh sind, weil die zwei- oder mehrfachen Parallelwicklungen keine oder nur eine sehr kleine Potentialdifferenz untereinander aufweisen.According to the invention, the collector is to be replaced by electronic switches and the closed-loop Xrommel armature winding as a double or multiple winding are executed. The multiple winding is intended to interrupt the power supply when running and thus prevent the occurrence of higher opening voltages, which are easy to Destruction of the electronic switch. In addition, the circuitry is simplified Considerable effort, because extinction is very easy when using thyristors becomes, and the free time is so long that it never leads to short-circuit processes in anti-parallel operation of the individual winding groups can come. The preparation the double or multiple winding is very easy, as it is available as a two-wire or multi-wire Winding can be made and no special insulation measures are required because the two or more parallel windings are none or only one very have a small potential difference between themselves.

Die Doppel- oder Mehrfachparallelwicklungen sind grundaätilioh untereinander galvanisch getrennt und nur an den Speisepunkten über die elektronischen Schalter miteinander verbunden.The double or multiple parallel windings are basically each other galvanically separated and only at the feed points via the electronic switch connected with each other.

Die Arbeitswicklung soll nicht umlaufen, sondern in einer Ständerblechpaket untergebracht werden wie bei einer Drehstrommaachine. Der Läufer kann dann sogar ein Kurzschluß-Läufer wie bei der Induktionsmaschine oder ein Dauermagnet oder ein Polrad einer Synchronmaschine sein.The working winding should not run around, but in a stator core housed like a three-phase machine. The runner can then even a squirrel cage as in the induction machine or a permanent magnet or a Be the pole wheel of a synchronous machine.
