Abstract
Rotor eines Elektromotors mit einem Außenrotor in Form einer Buchse mit radial angeordneten Öffnungen im Boden und einem ringförmigen Magneten, dadurch gekennzeichnet, dass der Rotor ein hohler Metallzylinder mit gegossenem Boden ist, wobei der Boden, der die Öffnungen und Stege bildet, als axiales Flügelrad ausgebildet ist.Rotor of an electric motor with an outer rotor in the form of a bushing with radially arranged openings in the bottom and an annular magnet, characterized in that the rotor is a hollow metal cylinder with a cast bottom, wherein the bottom, which forms the openings and webs, formed as an axial impeller is.
Description
Das Gebrauchsmuster betrifft den Bereich Klimaanlagen, Lüftung und Luftaustausch, insbesondere Elektromotoren für Lüftungssysteme und deren Bauteile.The utility model relates to the field of air conditioning, ventilation and air exchange, in particular electric motors for ventilation systems and their components.
Elektromotoren mit einem Außenrotor bestehen aus einem Stator und einem Rotor. Der Rotor dreht unter Einwirkung von Anziehungs- und Abstoßungskräften, die sich infolge des Zusammenwirkens der an ihm befestigten Magneten und Statorwicklungen des Elektromotors entwickeln.Electric motors with an outer rotor consist of a stator and a rotor. The rotor rotates under the action of attraction and repulsion forces that develop as a result of the interaction of the magnets and stator windings of the electric motor attached thereto.
Es ist ein Ventilator bekannt, der aus einem elektrischen Motor mit einem Außenrotor besteht (Patent
Da die Temperatur des Stators während des Betriebs steigt und sich der Stator im Inneren des Rotors befindet, ist eine Ableitung der Wärme von dem Stator schwierig. Die Öffnungen dieser Art liefern keine ausreichende Kühlungswirkung und Ableitung der Wärme, die von dem Stator des Elektromotors erzeugt wird.Since the temperature of the stator increases during operation and the stator is inside the rotor, dissipation of the heat from the stator is difficult. The openings of this type do not provide sufficient cooling effect and dissipation of the heat generated by the stator of the electric motor.
Die dem Gebrauchsmuster zugrunde liegende Aufgabe ist eine Verbesserung des Aufbaus des Rotors eines Elektromotors mit einem Außenrotor, so dass eine Ableitung der Wärme in dem Elektromotor und eine Erhöhung der Kühlungswirkung ermöglicht werden.The object underlying the utility model is to improve the structure of the rotor of an electric motor with an outer rotor, so that a dissipation of the heat in the electric motor and an increase of the cooling effect are made possible.
Die Aufgabe wird durch den Rotor eines Elektromotors mit einem Außenrotor in Form einer Buchse mit radial angeordneten Öffnungen im Boden gelöst, die die Form eines axialen Flügelrads haben. Der Rotor ist ein Hohlzylinder mit einem Boden, der durch Aluminiumguss hergestellt wird, wodurch der Rotor die Form einer Buchse erhält. Der gegossene Boden hat die Form eines axialen Flügelrads und bildet auch die Öffnungen und Stege.The object is achieved by the rotor of an electric motor with an outer rotor in the form of a bushing with radially arranged openings in the bottom, which have the shape of an axial impeller. The rotor is a hollow cylinder with a bottom made of cast aluminum, giving the rotor the shape of a bushing. The cast floor has the shape of an axial impeller and also forms the openings and lands.
In Inneren des hohlen zylindrischen Teils des Rotors ist wenigstens ein ringförmiger Magnet angeordnet, der an der Innenfläche des Rotors anliegt. Die Buchse besteht aus einem Magnetleitermaterial und schließt das von dem wenigstens einen Magneten gebildete Magnetfeld.In the interior of the hollow cylindrical part of the rotor at least one annular magnet is arranged, which bears against the inner surface of the rotor. The socket consists of a magnetic conductor material and closes the magnetic field formed by the at least one magnet.
Das Wesen des Gebrauchsmusters wird durch die folgenden Zeichnungen erläutert, in denen:The essence of the utility model is explained by the following drawings, in which:
Die Stege (
Die Drehung der Stege (
So wird durch die Verbesserung des Aufbaus des Rotors des Elektromotors eine Wärmeableitung in dem Elektromotor und eine Erhöhung der Kühlungswirkung ermöglicht.Thus, by improving the structure of the rotor of the electric motor, heat dissipation in the electric motor and increase of the cooling effect are enabled.
