Elektrische MaschineElectric machine
Offene elektrische Maschinen besitzen entweder Durchzugbelüftung oder Wickelkopfbelüftung. Bei Durchzugbelüftung sitzt auf der Läuferwelle ein Lüfterrad, während bei der Wickelkopfbelüftung Lüfterflügel einfach an den Stirnseiten des Läufers angebracht sind. Bei kleinen Maschinen verwendet man wegen der Raumausnutzung meistens die letztgenannte Belüftungsart, wobei allerdings die geförderte Luftmenge und damit die Wärmeabfuhr durch den geringen Lüfterdurchmesser begrenzt ist.Open electrical machines have either through ventilation or winding head ventilation. With draft ventilation sits a fan wheel on the rotor shaft, while fan blades are simply attached to the end faces of the rotor for winding head ventilation are attached. In the case of small machines, the latter type of ventilation is usually used because of the space utilization, whereby however, the amount of air conveyed and thus the heat dissipation is limited by the small fan diameter.
Die Neuerung stellt sich die Aufgabe, bei einer elektrischen Maschine mit Innenkühlung durch einen außerhalb der Ständerwicklung angeordneten Schleuderlüfter mit einfachen Mitteln eine hohe Kühlwirkung zu erzielen. Sie erreicht dies dadurch, daß der Schleuderlüfter in an sich bekannter Weise mit einer die Lüfterschaufeln in radialer Richtung unterteilenden und damit den geteilten Luftstrom sowohl über den Wickelkopf als auch von innen durch diesen hindurch führenden ringförmigen Trennwand versehen ist. Zusätzlich kann auch der Läufer in an sich bekannter Weise noch mit Lüfterflügeln versehen werden. Beide Luftströme werden dann durch einen Ringkanal zwischenThe innovation is the task of an electrical machine with internal cooling by an outside of the stator winding arranged centrifugal fan to achieve a high cooling effect with simple means. It does this by that the centrifugal fan in a known manner with a fan blades dividing in the radial direction and so that the split air flow both over the end winding and from the inside through this ring-shaped Partition is provided. In addition, the rotor can also be provided with fan blades in a manner known per se. Both air flows are then through an annular channel between

Es wird also hier praktisch die Durchzugbelüftung und die Wickelkopfbelüftung kombiniert, wodurch die geförderte Luftmenge wesentlich gesteigert wird, ohne daß das Bauvolumen der Maschine erheblich vergrößert werden muß.Motor housing and stator and then also cool the winding head on the other side of the stator. So it will be here practically the draft ventilation and the winding head ventilation combined, which significantly increases the amount of air conveyed without the structural volume of the machine having to be increased significantly.
