Description
Mit einem Stator und einem Rotor versehene magnetelektrische Maschine. Bei den bisher gebräuchlichen, mit einem Stator und einem Rotor versehenen magnet elektrischen Maschinen konnte der magneti sche Widerstand des Luftspaltes nur durch kleinstmögliche Dimensionierung desselben und Verwendung breiter Polschuhe auf ein Mindestmass herabgesetzt werden. Der für eine reibungslose Drehung des Rotors im Stator notwendige kleinste Spielraum ergab aber immer noch einen verhältnismässig grossen magnetischen Widerstand im Luftspalt.
Gegenstand vorliegender Erfindung ist nun eine einen Stator und einen Rotor auf weisende magnetelektrische Maschine, bei welcher der magnetische Widerstand des Luftspaltes auf ein wesentlich geringeres Mass gebracht werden kann, als bei den be kannten Maschinen dieser Art. Dies wird dadurch erreicht, dass die den Luftspalt be grenzenden Teile des Stators und des Rotors zahnartig ineinander greifen.
Die Zeichnung zeigt in schematischer Darstellung einen Achsialschnitt durch ein Ausführungsbeispiel des Erfindungsgegen standes.
1 sind die lamellierten Pole des Stators, 2 ist das lamellierte Blechpaket des Rotors, 3 ist die Statorwicklung, 4 bezeichnet die Ankerwicklung. Stator- und Rotoreisen sind mit Nuten versehen. Im vorliegenden Beispiel sind die Nuten des Rotors in sich geschlossene Ringnuten, während die Nuten im Stator infolge der zwischen den Statorpolen vor handenen Lücken Teile von Ringnuten sind. Die dadurch gebildeten Stege des einen Teils greifen in die Nuten des. andern Teils hinein, derart, dass sie sich bei kleinstmöglichem Abstand nirgends berühren.
Zufolge dieser Ausbildung der Stator- und Rotoreisen ist der dem Flug im Luft spalt gebotene Querschnitt bedeutend grösser als bei glatter Ausführung der Eisenflächen. Der magnetische greis hat infolgedessen einen geringeren Widerstand als bei der üblichen Gestaltung der einander gegenüber stehenden Flächen von Stator und Rotor. Zur Herstellung der Nuten und Stege lässt man vorteilhaft einzelne Lamellen in regelmässigen Abständen in radialer Richtung über die andern Lamellen vorstehen. Die Nuten haben dann rechteckiges Profil.
Sie können jedoch auch auf andere Art, beispiels weise durch Fräsen oder Hobeln hergestellt werden und irgend einen andern, zum Beispiel einen trapezförmigen oder dreieckigen, Quer schnitt aufweisen.
Wenn dies wünschbar erscheint, können die Pole statt lamelliert auch gegossen sein. Die erfindungsgemässe Maschine kann auch mit stehender Achse gebaut sein.
Magnetic electric machine provided with a stator and a rotor. In the previously used magnet-electric machines provided with a stator and a rotor, the magnetic resistance of the air gap could only be reduced to a minimum by the smallest possible dimensioning of the same and the use of wide pole pieces. However, the smallest clearance necessary for smooth rotation of the rotor in the stator still resulted in a relatively large magnetic resistance in the air gap.
The present invention is a stator and a rotor pointing magneto-electric machine, in which the magnetic resistance of the air gap can be brought to a much lower level than in the known machines of this type. This is achieved in that the air gap be bordering parts of the stator and the rotor mesh like teeth.
The drawing shows a schematic representation of an axial section through an embodiment of the subject of the invention.
1 is the laminated poles of the stator, 2 is the laminated core of the rotor, 3 is the stator winding, 4 is the armature winding. The stator and rotor bars are grooved. In the present example, the grooves of the rotor are self-contained annular grooves, while the grooves in the stator are parts of annular grooves due to the gaps between the stator poles. The webs formed in this way of the one part engage in the grooves of the other part in such a way that they do not touch anywhere with the smallest possible distance.
As a result of this design of the stator and rotor iron, the cross-section offered for flight in the air gap is significantly larger than with a smooth design of the iron surfaces. As a result, the magnetic old has a lower resistance than with the usual design of the surfaces of the stator and rotor that face one another. To produce the grooves and webs, individual lamellae are advantageously allowed to protrude over the other lamellae at regular intervals in the radial direction. The grooves then have a rectangular profile.
However, they can also be produced in other ways, for example by milling or planing and have any other, for example a trapezoidal or triangular cross-section.
If this appears to be desirable, the poles can also be cast instead of laminated. The machine according to the invention can also be built with a vertical axis.
