 treiben, kann man die Austrittsöffnungen der Läuferkanäle c durch ein gegebenenfalls verstellbares
Blech   r verschliessen   ; auch teilweiser Verschluss dieser Öffnungen ist möglich. 



   Die neue   Lüftungsart   lässt sich auch bei andern Maschinenarten, bei Synchronmaschinen, bei   Wechselstrom-und Gleichstrom-Kollektormaschinen   anwenden. Bei den letzteren lässt sich die   Kollektorkühlung sehr   vorteilhaft in den Kühlluftstrom einbeziehen. 



   PATENT-ANSPRtCHE :
1. Elektrische Maschine mit Eigenlüftung durch einen in den antriebsseitigen Lagerschild eingebauten Lüfter, welcher einen den Läuferdurchmesser übersteigenden   Aussendurchmesser   besitzt und die Kühlluft sowohl axial durch das Läuferinnere und parallel dazu über den   Ständerrücken   als auch radial durch Luftschlitze im Eisenkörper hindurchsaugt, dadurch gekennzeichnet, dass der
Lüfter die Frischluft durch eine Öffnung in einem unteren Abschnitt des Umfanges des einen Lager- schildes etwa radial ansaugt und die Abluft aus Öffnungen in einem gegen die Ansaugöffnung ver- setzten Abschnitt des Umfanges des andern Lagerschildes wenigstens über einen Teil des Ständer- gehäuses in axialer Richtung fortbläst, derart, dass sich generell ein etwa S-förmiger Kühlluftstrom ergibt.

 drive, you can the outlet openings of the rotor channels c by an optionally adjustable
Close tray r; Partial closure of these openings is also possible.



   The new type of ventilation can also be used with other types of machines, with synchronous machines, with alternating current and direct current collector machines. With the latter, the collector cooling can be incorporated very advantageously into the cooling air flow.



   PATENT CLAIMS:
1. Electrical machine with self-ventilation through a fan built into the drive-side end shield, which has an outer diameter exceeding the rotor diameter and which sucks the cooling air axially through the rotor interior and parallel to it over the stator back as well as radially through air slots in the iron body, characterized in that the
The fan draws in fresh air approximately radially through an opening in a lower section of the circumference of one bearing shield and the exhaust air from openings in a section of the circumference of the other bearing shield offset from the intake opening at least over part of the stator housing in the axial direction blows away in such a way that there is generally an approximately S-shaped flow of cooling air.

Claims (1)

2. Maschine nach Anspruch 1, dadurch gekennzeichnet, dass die Ansaugöffnung weniger, die Ausblasöffnung mehr als die Hälfte des betreffenden Lagerschildes umfasst. 2. Machine according to claim 1, characterized in that the suction opening is less that Blow-out opening covers more than half of the bearing plate concerned. 3. Maschine nach Anspruch 1, dadurch gekennzeichnet, dass die axialen Luftaustrittskanäle in dem den Lüfter enthaltenden Lagerschild mit Leitschaufeln für die Abluft versehen sind. EMI2.1 3. Machine according to claim 1, characterized in that the axial air outlet ducts in the end shield containing the fan are provided with guide vanes for the exhaust air. EMI2.1
