    <title language="eng">Rotor for an Electric Machine Having Magnets Secured by a Thermoplastic Material and Corresponding Manufacturing Method (Patent)</title>
    <abstract language="deu">Es wird ein Rotor für eine Elektromaschine sowie ein Verfahren zum Herstellen eines solchen Rotors beschrieben. Der Rotor (15) weist einen Rotorkörper (9) mit einer Mehrzahl von Ausnehmungen (5) und einer Mehrzahl von Magneten (7), die in die Ausnehmungen (5) des Rotorkörpers (9) aufgenommen sind, auf. Die Magneten (7) sind wenigstens teilweise von einem thermoplastischen Material umgeben und durch dieses in den Ausnehmungen (5) fixiert. Im Vergleich zu herkömmlichen duroplastischen Klebstoffen ermöglichen thermoplastische Materialien ein einfacheres, formschlüssiges Fixieren der Magneten (7) in dem Rotorkörper (9). In das thermoplastische Material (13) können magnetische oder magnetisierbare Partikel eingelagert sein, so dass ein mit dem thermoplastischen Material (13) aufgefüllter Spalt (11) zwischen den Magneten (7) und den Wandungen der Ausnehmungen (5) zum gesamten, von dem Rotor erzeugten Magnetfeld beitragen kann.</abstract>
    <abstract language="eng">The invention relates to a rotor for an electric machine and to a method for manufacturing such a rotor. The rotor (15) comprises a rotor body (9) having a plurality of holes (5) and a plurality of magnets (7) that are accommodated in the holes (5) of the rotor body (9). The magnets (7) are enclosed at least partially by a thermoplastic material and secured by the latter in the holes (5). In comparison to conventional duroplastic adhesives, the thermoplastic materials enable a simpler positive locking securing of the magnets (7) in the rotor body (9). Magnetic or magnetizable particles can be embedded in the thermoplastic material (13), such that a gap (11) between the magnets (7) and the walls of the holes (5), which gap is filled with the thermoplastic material (13), can contribute to the total magnetic field generated by the rotor.</abstract>

    <title language="eng">Asynchronous Machine with Optimized Distribution of Electrical Losses Between Stator and Rotor (Patent)</title>
    <abstract language="deu">Es wird eine Asynchronmaschine (1) vorgeschlagen, wie sie insbesondere in Elektrofahrzeugen oder Hybridfahrzeugen eingesetzt werden kann. Die Asynchronmaschine (1) weist einen Rotor (5) und einen Stator (3) auf. Die Asynchronmaschine ist derart aufgebaut und angesteuert, dass sie eine Polpaarzahl p von p=3 aufweist. Aufgrund der hierdurch erreichbaren verringerten Jochsättigung kann das Statorjoch (9) mit einer geringeren Höhe hy1 ausgebildet werden, so dass ein Verhältnis von Rotoraußendurchmesser D2a zu Statoraußendurchmesser D1a Werte zwischen 0,7 und 0,8 annehmen kann. Hierdurch lassen sich im Rotor (5) vergrößerte Rotorzähne (19) und entsprechend vergrößerte Rotornuten (21) ausbilden, so dass elektrische Verluste in dem als Rotorspulenelement (23) dienenden Material in den Rotornuten (21) im Vergleich zu herkömmlichen Asynchronmaschinen geringer sind. Die als Ausgleich in dem Stator (3) verstärkt auftretenden elektrischen Verluste führen zu einer geringeren Erwärmung des Stators (3) als dies beim Rotor (5) der Fall wäre, da sich der Stator (3) mit einfachen Mitteln kühlen lässt. Insgesamt kann somit mit der vorgeschlagenen Asynchronmaschine (1) ein höheres Dauerdrehmoment erreicht werden.</abstract>
    <abstract language="eng">The invention relates to an asynchronous machine (1) as can be used particularly in electric vehicles or hybrid vehicles. The asynchronous machine (1) has a rotor (5) and a stator (3). The asynchronous machine is designed and controlled in such a manner that it has a pole pair number p of p=3. Because of the reduced yoke saturation that can consequently be achieved, the stator yoke (9) can be designed with a lesser height hy1, such that a ratio of the outer rotor diameter D2a to the outer stator diameter D1a can assume values between 0.7 and 0.8. As a result, enlarged rotor teeth (19) and correspondingly enlarged rotor grooves (21) can be formed in the rotor (5), such that electrical losses in the material in the rotor grooves (21) acting as the rotor coil element (23) are smaller in comparison to conventional asynchronous machines. The electrical losses occurring to a greater extent in the stator (3) compensating for this lead to a lesser warming of the stator (3) than would be the case with the rotor (5) as the stator (3) can be cooled by simple means. Overall, a higher continuous torque can thus be achieved with the asynchronous machine (1) according to the invention.</abstract>

La saturation de la culasse peut ainsi être réduite, ce qui permet de concevoir une culasse de stator (9) présentant une hauteur réduite hy1, de sorte que le rapport entre le diamètre extérieur de rotor D2a et le diamètre extérieur de stator D1a peut être compris entre 0,7 et 0,8. Le rotor (5) peut ainsi être pourvu de dents de rotor (19) plus grandes et donc d'encoches de rotor (21) plus grandes, ce qui permet de réduire les pertes électriques dans le matériau servant d'élément de bobine rotorique (23) dans les encoches de rotor (21) par comparaison avec les machines asynchrones classiques. Les pertes électriques accrues survenant en compensation dans le stator (3) entraînent un échauffement réduit du stator (3) comparativement à ce qui se produirait dans le rotor (5), du fait que le stator (3) peut être refroidi avec des moyens simples. La machine asynchrone (1) selon l'invention permet globalement d'obtenir un couple de rotation continu plus élevé.</abstract>

The asynchronous machine (1) has a rotor (5) and a stator (3). The asynchronous machine is designed and controlled in such a manner that it has a pole pair number p of p=3. Because of the reduced yoke saturation that can consequently be achieved, the stator yoke (9) can be designed with a lesser height hy1, such that a ratio of the outer rotor diameter D2a to the outer stator diameter D1a can assume values between 0.7 and 0.8. As a result, enlarged rotor teeth (19) and correspondingly enlarged rotor grooves (21) can be formed in the rotor (5), such that electrical losses in the material in the rotor grooves (21) acting as the rotor coil element (23) are smaller in comparison to conventional asynchronous machines. The electrical losses occurring to a greater extent in the stator (3) compensating for this lead to a lesser warming of the stator (3) than would be the case with the rotor (5) as the stator (3) can be cooled by simple means. Overall, a higher continuous torque can thus be achieved with the asynchronous machine (1) according to the invention., type = patent, author = Ruiz De Larramendi, Miguel and Heuser, Patrick and Herranz Gracia, Mercedes, urldate = 2021-09-27, date = 2014-06-19, langid = english, note = WO2014090440, keywords = Asynchronous Machine with Optimized Distribution of Electrical Losses Between Stator and Rotor, file = Snapshot:/home/mercedes/snap/zotero-snap/common/Zotero/storage/RIVQXW9A/detail.html:text/html,</enrichment>

    <title language="eng">Structure-Dynamic Analysis of an Induction Machine depending on Stator-Housing Coupling</title>
    <abstract language="eng">The estimation and calculation of the acoustic sound of electric machinery is of high interest. Various approaches have been presented relying either on analytical or on numerical models. In general, the analytical models are based on the electromagnetic-field theory and the results are compared to measurements. Numerical models allow for the separation of different exciting forces stemming from various effects. In the studied case of an induction motor with squirrel-cage rotor three effects are taken into account in the analytical model: the fundamental field, saturation, and eccentricity. The numerical analysis is applied for the analysis of acoustic sound of an electric machine. Nevertheless, the numerical results have to be verified. Hence, they are compared to the physically based analytical results. The radiated noise depends directly on the surface's deformation of the machine. Therefore, the analysis is focused on the structure-dynamic vibrations. The combined analysis presented here, allows for the reduction of vibrations and noise optimizing the coupling of stator and housing. Here, an induction machine (IM) with squirrel-cage rotor is studied. Its housing is mounted with six spiral-steel springs to the stator. With the presented method the impact of different numbers of springs is analyzed.</abstract>

    <title language="eng">Influence of the magnetic anisotropy on electrical machines</title>
    <abstract language="eng">Non grain-oriented electrical steel has an inherent anisotropy, which is normally neglected in the calculation of electrical machines. Moreover, the magnetic anisotropy is usually measured in small material samples. Due to the cutting effect, the magnetic anisotropy in the machine is not the same as in the sample. In this paper, the magnetic anisotropy is considered as a global problem. A method to measure it is presented and its influence on the electromagnetic and acoustic behavior is considered through the example of an induction motor.</abstract>
