Es ergibt sich eine kompakte Konstruktion durch Wegfall von Riemen, Getriebe, Hydraulikkomponenten und Kupplungen. Hohe Leistungsdichte durch Flüssigkeitskühlung. Hohe Genauigkeit am Werkstück durch steifen Antriebsstrang. Ein zusätzlicher Lagegeber entfällt. Einfache Spindelkonstruktion mit 90% weniger Verlustleistung im Rotor, d.h. wesentlich geringere Lageerwärmung. Höherer Wirkungsgrad und weniger Kühlleistung.This results in a compact design due to the elimination of belts, gears, hydraulic components and couplings. High power density due to liquid cooling. High accuracy on the workpiece due to a rigid drive train. An additional position sensor is not required. Simple spindle design with 90% less power loss in the rotor, i.e. significantly lower bearing heating. Higher efficiency and less cooling capacity.
Weiterhin ergibt sich eine kompaktere Maschinenkonstruktion mit einem höheren Drehmoment (ca. 60%) bei gleichem Aktivteilvolumen. Die Folge sind bessere Arbeitsergebnisse.Furthermore, the result is a more compact machine design with a higher torque (approx. 60%) with the same active part volume. The result is better work results.
Die thermische Ausnutzbarkeit ist bei Nenndrehzahl um bis zu 70% und bei Maximaldrehzahl bis zu 100% höher. Dabei liegt eine höhere Überlastbarkeit (keine Kippgrenze) und geringere Nebenzeiten von ca. 50% vor.The thermal utilization is up to 70% higher at nominal speed and up to 100% higher at maximum speed. This means that there is a higher overload capacity (no tipping point) and lower idle times of around 50%.
In FIG 2 bezeichnet 4 die Hohlwelle, 5 den Läufer, 6 die Hülse, 7 den Luftspalt und 8 den Ständer einer erfindungsgemäßen Einbaumotoreinheit in permanenterregter Bauart.In FIG 2, 4 designates the hollow shaft, 5 the rotor, 6 the sleeve, 7 the air gap and 8 the stator of a built-in motor unit according to the invention in a permanently excited design.
Allgemein ist zu den Einbaumotoreinheiten in permanenterregter Ausführung folgendes zu bemerken:In general, the following should be noted regarding the built-in motor units in permanent magnet design:
Die erheblich reduzierte Wärmeentwicklung kommt der Spindelausdehnung und -lagerung zugute. Die Läuferverlustleistung ist - bei gleicher Nennleistung - gegenüber einer Asynchronmaschine um ca. 90% reduziert. Der Rotor wird lediglich von der Reibung der Lager und den Dichtelementen erwärmt. Dazu kommt noch die Luftreibung sowie die Wärme der Wicklung bzw. Wickelköpfe, die durch Konvektion übertragen wird. Außerdem ist der Kühlaufwand gering. Ein nicht zu vernachlässigender Punkt, wenn man 1 Watt Kühlleistung mit einer DM an Aufwand zugrundelegt.The significantly reduced heat development benefits the spindle expansion and bearings. The rotor power loss is - with the same nominal power - reduced by around 90% compared to an asynchronous machine. The rotor is only heated by the friction of the bearings and the sealing elements. In addition, there is air friction and the heat of the winding or winding heads, which is transferred by convection. In addition, the cooling effort is low. A point that should not be neglected if one bases 1 watt of cooling power on one DM of effort.
Die Aufstellfläche der Maschine, die reduziert werden kann, ist ein wichtiger Gesichtspunkt. Im unteren DrehzahlbereichThe footprint of the machine, which can be reduced, is an important consideration. In the lower speed range
GR 98 G 3192GR 98 G 3192
ist die Drehmomentdichte gegenüber der Asynchronmaschine um bis zu 80% höher.The torque density is up to 80% higher than that of an asynchronous machine.
Die Produktivität der Maschine steigt sowohl durch eine höhere Leistungsdichte (bei gleichem Bauvolumen) im oberen Drehzahlbereich, was kürzere Nebenzeiten (z.B. Hochlauf) bringt, als auch durch die Reduzierung des Massenträgheitsmomentes bei gleicher Leistung. Besonders vorteilhaft ist die Möglichkeit, entsprechende Einbaumotoreinheiten in der Ausführung als Standardantriebseinheiten zu verwenden. Diese Standardantriebseinheiten sind bekannt und werden unter dem Markennamen "SIMODRIVE IFE" von der Siemens AG vertrieben. Zum Betrieb entsprechender Einbaumotoren steht eine entsprechende Regelungssoftware zur Verfügung. Diese Software ist auf den heute bekannten Hardwarekomponenten des SIMODRIVE 611 lauffähig. Zum Einsatz kommen FE-Einbaumotoren mit der CNC-Steuerung SINUMERIK 840D und dem Umrichtersystem SIMODRIVE 611 mit digitaler Regelung. Bei diesen Komponenten handelt es sich um Erzeugnisse der Firma Siemens AG, die bisher noch nicht für den Antrieb von Kunststoffmaschinen verwendet wurden.The productivity of the machine increases both through a higher power density (with the same construction volume) in the upper speed range, which results in shorter idle times (e.g. start-up), and through the reduction of the mass moment of inertia with the same power. The possibility of using corresponding built-in motor units in the design as standard drive units is particularly advantageous. These standard drive units are well-known and are sold by Siemens AG under the brand name "SIMODRIVE IFE". Appropriate control software is available for operating corresponding built-in motors. This software can run on the currently known hardware components of the SIMODRIVE 611. FE built-in motors with the SINUMERIK 840D CNC control and the SIMODRIVE 611 converter system with digital control are used. These components are products from Siemens AG that have not yet been used to drive plastics machines.
