- d) der Wirkungsgrad einer Baueinheit "Elektromotor- Maschine" oder Anlage wesentlich gesteigert werden kann, indem der Läufer je nach Bedarf der Kraftüber tragung bzw. des anzutreibenden Anlagenteils z. B. als Sechskant, Verzahnung, Paßsitz etc. ausgeführt wird, oder gleich die Form des rotierenden Maschi nenteils z. B. Lüfterflügel, Gebläselaufrad, Rolle, Walze, Zahnrad, Bohrer etc. erhält und dadurch zu sätzliche Lager-, Reibungs- und Kraft-Übertragungs verluste entfallen.d) the efficiency of a structural unit "electric motor Machine "or plant can be increased significantly can by moving the runner as needed carry or the system part to be driven z. B. designed as a hexagon, toothing, snug fit, etc. or the shape of the rotating machine partly z. B. fan blades, fan impeller, roller, Receives roller, gear, drill etc. and thereby additional bearing, friction and power transmission losses are eliminated.
In Ausführungsbeispiel Fig. 1 ist der Läufer (1) mit den daran abgedichtet angeflanschten Lagerschildern (6, 7) über die Lager (5) und die Gleitringdichtungen (9) auf der Stator-Hohlwelle (3) drehbar angeordnet.In the embodiment shown in FIG. 1, the rotor ( 1 ) with the bearing plates ( 6, 7 ) sealed thereon is rotatably arranged on the stator hollow shaft ( 3 ) via the bearings ( 5 ) and the mechanical seals ( 9 ).
Auf der Stator-Hohlwelle (3) sitzt der Stator (2), der aus Sta torblechpaket und Statorwicklung besteht. Der elek trische Anschluß der Statorwicklung und der in der Sta torwicklung integrierten Temperaturfühler bzw. Thermo kontakte, erfolgt über die durch die Hohlwelle (3) geführ te Anschlußleitung (13). Die Wicklungsköpfe (8) der Sta torwicklung sind in ihrer Ausgestaltung der inneren Form der Lagerschilde (6) und (7) angepaßt.On the stator hollow shaft ( 3 ) sits the stator ( 2 ), which consists of stacked stator core and stator winding. The electrical connection of the stator winding and the temperature sensor or thermal contacts integrated in the stator winding takes place via the connecting cable ( 13 ) guided through the hollow shaft ( 3 ). The winding heads ( 8 ) of the gate winding are adapted in their design to the inner shape of the end shields ( 6 ) and ( 7 ).
Das Lagerschild (6) ist auf der Innenseite mit Leitschaufeln (15) versehen und als Pumpenlaufrad ausgebildet und in der Formgebung dem Wicklungskopf (8) angepaßt. Durch die spezielle, aufeinander abgestimmte Form von Lagerschild (6) mit Leitschaufeln (15) und dem Wicklungskopf (8), ent steht im Motorinnenraum eine Kreiselpumpe zur Förderung der Kühlflüssigkeit. Das Lagerschild (7) ist auf der Innensei te ebenfalls der Form des Wicklungskopfes (8) angepaßt um dort eine gute Umspülung des Wicklungskopfes, eine hohe Fließgeschwindigkeit der Kühlflüssigkeit und somit eine best mögliche Kühlung der Statorwicklung zu erreichen. Zur Steigerung der Kühlleistung können, je nach Erfordernis, noch zusätzliche Kühlbohrungen bzw. Kühlkanäle (17 und 18) entlang der Statorwicklung in axialer Richtung, oder bei Motoren mit beidseitig integrierter Pumpe, auch in radialer Richtung angebracht werden. The bearing plate ( 6 ) is provided on the inside with guide vanes ( 15 ) and designed as a pump impeller and the shape of the winding head ( 8 ) is adapted. Due to the special, coordinated shape of the end shield ( 6 ) with guide vanes ( 15 ) and the winding head ( 8 ), a centrifugal pump is created in the engine compartment to convey the coolant. The end shield ( 7 ) is also adapted to the shape of the winding overhang ( 8 ) on the inner side to achieve a good washing around the winding overhang, a high flow rate of the cooling liquid and thus the best possible cooling of the stator winding. To increase the cooling capacity, additional cooling holes or cooling channels ( 17 and 18 ) can be made along the stator winding in the axial direction or, in the case of motors with a pump integrated on both sides, in the radial direction, depending on the requirements.
Die staubdichte Abdeckung der Gleitringdichtungen (9) und der Lager (5), oder bei umgekehrter Anordnung, - Lager (5) und Gleitringdichtungen (9) - welche je nach Lagerart oder Bedarf gewählt werden kann, erfolgt über die Lagerdeckel (16).The dust-proof cover of the mechanical seals ( 9 ) and the bearings ( 5 ), or in the reverse arrangement, - bearings ( 5 ) and mechanical seals ( 9 ) - which can be selected depending on the type of bearing or need, takes place via the bearing cover ( 16 ).
Bei der Ausführung nach Fig. 1, erfolgt die Kühlung und Schmierung der Lager und Gleitringdichtungen durch das Kühlmittel.In the embodiment of Fig. 1, the cooling and lubrication of the bearings and mechanical seals carried by the coolant.
Über die Hohlwelle (3), die an ihren beiden Enden durch die Stopfen (11) und (12) abgedichtet verschlossen ist, erfolgt die Kühlflüssigkeits-Verteilung im Motor, d. h. die Trennung in eine Motor-Saugseite, bzw. Motor-Druck seite. In der Hohlwelle (3) sind auch zur Kühlmittelver teilung die Radialbohrungen (14) und (14 a) angebracht. Ebenfalls in der Hohlwelle montiert sind ein oder mehrere Druckausgleichsvorrichtungen (4) zum Volumen- bzw. Druck ausgleich des Kühlmittels. Wird nun durch Einschalten des Motors der Läufer in Bewegung ge setzt, so saugt die im Motor integrierte Pumpe (Teile 8, 15 und 6) über die Radialbohrungen (14), Kühlmittel aus der Hohlwelle (3) an und drückt das Kühlmittel über den Ringspalt zwischen Läufer und Stator, sowie andere je nach Bedarf angebrachte Kühlbohrungen, weiter über den Spalt zwischen Lagerschild (7) und Wicklungskopf (8), die Radial bohrungen (14 a) in die Hohlwelle (3) zurück. Diese Ausfüh rungsart ist für alle Motoren geeignet, bei denen die Küh lung des Stators im Vordergrund steht und die erforderliche Wärmeabfuhr über den Läufer an die Umgebung oder das Förder medium oder das anzutreibende Maschinenteil möglich ist. About the hollow shaft ( 3 ), which is sealed at both ends by the plugs ( 11 ) and ( 12 ), the coolant is distributed in the engine, ie the separation into an engine suction side or engine pressure side. In the hollow shaft ( 3 ), the radial bores ( 14 ) and ( 14 a) are also provided for coolant distribution. One or more pressure compensation devices ( 4 ) for volume or pressure compensation of the coolant are also mounted in the hollow shaft. If the rotor is started by switching on the motor, the pump integrated in the motor (parts 8, 15 and 6 ) sucks in coolant from the hollow shaft ( 3 ) via the radial bores ( 14 ) and presses the coolant through the annular gap between the rotor and the stator, as well as other cooling bores as required, further over the gap between the end shield ( 7 ) and the winding head ( 8 ), the radial bores ( 14 a) in the hollow shaft ( 3 ). This type of design is suitable for all motors in which the cooling of the stator is in the foreground and the necessary heat dissipation via the rotor to the environment or the medium to be conveyed or the machine part to be driven is possible.
Das Beispiel in Fig. 2 zeigt einen erfindungsgemäßen Motor mit zusätzlichen Anschlüssen (19 und 20) für ein externes Kühlsystem und/oder externe Kühlmittelpumpe. Bei dieser Ausführungsart wird über die Trennscheibe (21), der Motor in eine Saug- und Druckseite, bzw. eine Kühlmitteleintritt- und Kühlmittelaustrittseite, unterteilt.The example in FIG. 2 shows an engine according to the invention with additional connections ( 19 and 20 ) for an external cooling system and / or external coolant pump. In this embodiment, the motor is divided into a suction and pressure side or a coolant inlet and coolant outlet side via the cutting disc ( 21 ).
Fig. 3 zeigt einen Motor entsprechend Fig. 2, jedoch mit anderer Formgebung der Pumpenleitschaufeln (15), der Wick lungsköpfe (8) und der Innenseite des Lagerschildes (7). Fig. 3 shows a motor corresponding to FIG. 2, but with a different shape of the pump guide vanes ( 15 ), the winding heads ( 8 ) and the inside of the end shield ( 7 ).
Fig. 4 zeigt einen erfindungsgemäßen Motor entsprechend Fig. 1, jedoch nur mit einseitig ausgeführtem Wellenende als Montagefestpunkt. Außerdem entfällt bei dieser Ausführungsform Gleitringdichtung und das Lagerschild (7) bildet mit dem Läufer (1) eine Einheit. Fig. 4 shows a motor according to the invention corresponding to Fig. 1, but only with a shaft end designed as a fixed assembly point. In addition, in this embodiment there is no mechanical seal and the bearing plate ( 7 ) forms a unit with the rotor ( 1 ).
