Abstract
Getriebeloser elektrischer Antriebsmotor dadurch gekennzeichnet, dass Dieser aus einer Anzahl mehrerer, einzelner elektrischer Statorwicklungen 3 und einem gemeinsamen permanent erregten Rotor, oder aus einer gleichen Anzahl mechanisch verbundenen, permanent erregten Rotorreihen 1 besteht. Die einzelnen elektrischen Statorwicklungen 3 sind elektrisch und mechanisch so verbunden das Diese die Summe der Einzelleistungen als Gesamtleistung/Nennleistung erbringen können.Gearless electric drive motor characterized in that it consists of a number of several, individual electrical stator windings 3 and a common permanently excited rotor, or of an equal number of mechanically connected, permanently excited rotor rows 1. The individual electrical stator windings 3 are electrically and mechanically connected so that they can provide the sum of the individual powers as total power / nominal power.
Description
Elektrische Antriebe üblicher Bauweise weisen eine Wicklung, einen Rotor und ein Getriebe zum Erreichen einer erforderlichen Drehzahl bei einer gegebenen Leistung auf. Analog zu steigender Nennleistung steigt die Leerlaufleistung. Das heißt: Umso größer der Antrieb ist desto höher ist die Leerlaufleistung. Die Leerlaufleistung ist die erforderliche Mindestleistung eines elektrischen Motors im Betrieb ohne Last.Electric drives of conventional design have a winding, a rotor and a gear to achieve a required speed at a given power. The idle power increases in the same way as the nominal power increases. This means that the larger the drive, the higher the idling power. The no-load power is the minimum required power of an electric motor during no-load operation.
Durch einen Getriebewirkungsgrad wird anteilig der Gesamtwirkungsgrad des Antriebes gemindert und die Mindestleistung erhöht. In der üblichen Getriebebauweise wird die Drehzahl des elektrischen Motors reduziert und das erzeugte Drehmoment des elektrischen Motors erhöht.By means of a transmission efficiency, the overall efficiency of the drive is proportionally reduced and the minimum power is increased. In the usual transmission design, the speed of the electric motor is reduced and increases the torque generated by the electric motor.
Die konstruktive Bestimmung der erforderlichen Größe eines Antriebes in Leistung, Drehmoment und Drehzahl beruht auf der mathematisch, physikalischen Berechnung der maximalen Volllastleistung und der technisch üblichen Sicherheitszuschläge. Die Volllast zum Beispiel einer Transportförderanlage mit einem elektrischen Antrieb wird durch die maximale Annahme möglich auftretender Lasten zuzüglich widriger aber plausibler Betriebszustände wie Überschüttung, Verklemmung und temporär überhöhte Reibung definiert. Diese Umstände treten selten auf und die üblichen Sicherheitszuschläge dienen der Anlagensicherheit.The constructive determination of the required size of a drive in power, torque and speed is based on the mathematical, physical calculation of maximum full load and the usual safety margins. The full load, for example, of a transport conveyor with an electric drive is defined by the maximum assumption of possible occurring loads plus adverse but plausible operating conditions such as overflow, deadlock and temporarily excessive friction. These circumstances rarely occur and the usual security surcharges are for plant safety.
Diese vorher beschriebene Leistungsbestimmung ist energetisch zutreffend, für elektrische Antriebe in einem stationären Lastbereich, wie Pumpen und Ventilatoren.This previously described power determination is energetically accurate for electric drives in a stationary load range, such as pumps and fans.
Für elektrische Antriebe welche in wechselnden Lastbereichen verwendet werden wie zum Beispiel Transportförderanlagen mit Leerlauf-, Teillast- und Volllastzeiten, stellt die nicht erforderliche Leerlaufleistung/Mindestleistung des elektrischen Antriebes einen unnötigen Energieverbrauch dar. In solchen, vorher genannten, Transportförderanlagen werden üblich Asynchrongetriebemotoren verwendet. Die Asynchrongetriebemotoren haben bauartbedingt einen Leerlaufleistungsbedarf von mindestens dem halben Betrag der Volllastleistung. Die Asynchrongetriebemotoren können dem verringerten Leistungsbedarf bei Teil- und Leerlaufleistung energetisch nicht entsprechen. Werden die Leerlauf- und Teillastbetriebszeiten solcher Transportförderanlagen berücksichtigt, so wird deutlich das die Energieeinsparungen in den Lastbereichen Leerlauf und Teillast weitaus größer sind als die Effizienz- und Wirkungsgradsteigerung des Vollastpunktes eines elektrischen Antriebes in einer solchen Anwendung. Weiterhin ist eine Überdimensionierung eines Antriebes ein fortwährender und nicht zu korrigierender Faktor für einen unnötigen Energieverbrauch.For electric drives which are used in varying load ranges such as transport systems with idling, part load and full load times, the unnecessary idling power / minimum power of the electric drive is an unnecessary energy consumption. Asynchronous geared motors are commonly used in such previously mentioned transport conveyor systems. The Asynchrongetriebemotoren have a design idling power requirement of at least half the amount of full load power. The Asynchrongetriebemotoren can not meet the reduced power requirements at part and idle power energetically. If the idling and part load operating times of such transport conveyor systems taken into account, it is clear that the energy savings in the load areas idle and part load are far greater than the efficiency and efficiency increase of the full load point of an electric drive in such an application. Furthermore, over-dimensioning a drive is a perennial and irreversible factor in unnecessary power consumption.
