Abstract
Description
Die Erfindung betrifft einen Außenläufermotor mit einem Innenstator und einem Außenrotor, welch letzterer nach Art einer Rotorglocke ausgebildet ist.The The invention relates to an external rotor motor with an inner stator and an outer rotor, which latter after Type of rotor bell is formed.
Bei derartigen Motoren wird zwar der Außenrotor durch die Luftströmung auf seiner Außenseite sehr gut gekühlt, aber die Wicklung des Innenstators erreicht bei guter Ausnutzung des Motors oft hohe Temperaturen, und diese können auch die Lebensdauer der Lager für die Rotorwelle beeinträchtigen.at Although such motors, the outer rotor by the air flow on its very outside well chilled, but the winding of the inner stator reaches with good utilization The engine often has high temperatures, and these can also increase the life of the engine Warehouse for affect the rotor shaft.
Es ist deshalb eine Aufgabe der Erfindung, einen neuen Außenläufermotor bereit zu stellen.It is therefore an object of the invention, a new external rotor motor to provide.
Nach der Erfindung wird diese Aufgabe gelöst durch den Gegenstand des Anspruchs 1. Im Betrieb erzeugt das Schaufelrad in einer radialen Ebene einen Luft-Volumenstrom im Inneren der Rotorglocke. Am Luftaustritt aus dem Schaufelrad befindet sich ein Umlenkglied, das im Betrieb von diesem Volumenstrom angeblasen wird und ihn umlenkt. Hierdurch entsteht auf der (nicht angeblasenen) Rückseite des Umlenkglieds ein statischer Unterdruck, der nach dem Prinzip der Bernoullidüse Frischluft durch die mindestens eine in der Rotorglocke vorgesehenen Durchbrechung in das Innere der Rotorglocke saugt. Diese Frischluft addiert sich zu der innerhalb des Motors kreisenden Kühlluft, so dass dort ein Überdruck entsteht und folglich eine korrespondierende erwärmte Luftmenge aus diesem Innenraum ausgeblasen wird.To the invention, this object is achieved by the subject of the Claim 1. In operation, the impeller generates in a radial Level an air volume flow inside the rotor bell. At the air outlet from the paddle wheel is a deflecting member, which is in operation is blown by this volume flow and deflects it. hereby arises on the (not blown) back of the deflector static negative pressure, according to the principle of Bernoulli nozzle fresh air by the at least one opening provided in the rotor bell opening sucked into the interior of the rotor bell. This fresh air adds to the cooling air circulating inside the engine so that there is an overpressure arises and thus blown out a corresponding heated amount of air from this interior becomes.
Im Innenraum des Außenläufermotors entsteht also eine aktive, erzwungene Wärmekonvektion durch die dort kreisende Luft, welche den Innenstator umso mehr kühlt, je schneller der Rotor rotiert, wobei diese erwärmte kreisende Luft ständig nach einer vorgegebenen Gesetzmäßigkeit durch kühlere Frischluft ersetzt wird und so das Innere des Motors kühlt.in the Interior of the external rotor motor So there is an active, forced heat convection by the there circulating air, which cools the inner stator all the more, depending faster the rotor rotates, with this heated circular air constantly after a predetermined law through cooler fresh air is replaced, thus cooling the interior of the engine.
