Abstract
Description
Die Erfindung betrifft eine permanentmagneterregte elektrische Maschine, insbesondere einen Rotor für einen solche Maschine. Permanentmagneterregte elektrische Maschinen, sei es als Generator oder als Motor, sind hinreichend bekannt.The Invention relates to a permanent-magnet-excited electric machine, in particular a rotor for such a machine. Permanent magnet excited electrical machines, be it as a generator or as an engine, are well known.
Die Erfindung befasst sich insbesondere mit Synchronmotoren, bei welchen der Rotor, vorgesehen mit Permanentmagneten, angeordnet als Flusskonzentrator sowie einen Käfig analog demjenigen eines gewöhnlichen Asynchronmotors enthält, derart, dass er durch Induktionswirkung anlaufen kann, bis er eine ausreichende Drehzahl erreicht hat, um sich dann unter Wirkung der Permanentmagnete synchronisiert.The Invention is particularly concerned with synchronous motors in which the rotor, provided with permanent magnets, arranged as a flux concentrator as well as a cage analogous to that of an ordinary one Contains asynchronous motor, such that it can start by induction until it has a has reached sufficient speed, then under the effect of Permanent magnets synchronized.
Ein Nachteil der bekannten permanentmagneteregten elektrischen Maschinen mit Flusskonzentrator sind der hohe Streuflussanteil.One Disadvantage of the known permanent magnet excited electrical machines with flux concentrator are the high leakage flux.
Ein weiterer Nachteil der bekannten permanentmagneterregten elektrischen Maschinen ist, dass Sie über keine hinreichende Dämpfung verfügen. Durch diesen Umstand muss die permanentmagenterregte elektrische Maschine in Verbindung mit einer Regeleinrichtung betrieben werden, da sie sonst bei entsprechenden Laststößen pendelt und instabil wird.One Another disadvantage of the known permanent magnet excited electrical Machines is you over no adequate damping feature. Due to this circumstance, the permanent magnet excited electrical Machine operated in conjunction with a control device, otherwise it will oscillate with corresponding load surges and become unstable.
Der Erfindung liegt daher die Aufgabe zugrunde, eine elektrische Maschine der eingangs genannten Art zu schaffen, die im Gegensatz zu elektrischen Maschinen aus dem Stand der Technik zum einen über einen Flusskonzentrator mit minimalem Streufluss und zum anderen über eine passive Anlauf- und Dämpfereinrichtung verfügt.Of the Invention is therefore the object of an electric machine of the type mentioned above, which in contrast to electrical State-of-the-art machines on the one hand via a flux concentrator with minimal stray flux and on the other hand via a passive start-up and damper device features.

Hierbei ist im einzelnen vorgesehen, dass der Stator Blechpakete aufweist, die dem Rotor zugerichtet sind und die mit dem auf dem Rotor angeordneten Polsystem zusammenwirken.in this connection is specifically provided that the stator has laminated cores, which are trimmed to the rotor and arranged with the rotor Polsystem interact.
Nach
einem besonderen Merkmal der Maschine werden die Permanentmagnetn
(
Da
am Rotor-Nutgrund sich die Permanetmagnete über das Dynamoblech kurzschließen würden, sind
erfindungsgemäß unterhalb
der beiden Nutzmagnete weitere Sättigungsmagnete
(
Durch die vorgesehene Anordnung der Magnete können zwischen den Magneten größere Stege vorgesehen werden, die auf Grund der zusätzlichen Magnete magnetisch gesättigt sind. Hieraus ergibt sich eine wesentlich größere mechanische Festigkeit des Rotors.By the intended arrangement of the magnets can be between the magnets provided larger webs that are due to the additional magnets magnetically saturated are. This results in a much greater mechanical strength of Rotor.
