    <title language="eng">An Energy-Based Harmonic Constitutive Law for Magnetic Cores With Hysteresis</title>
    <abstract language="eng">In this paper, a phenomenological energy-based material model for ferromagnetic materials under harmonic conditions is presented. The model is based on the concept of a complex effective permeability and an accurate representation of energy is adopted as identification criteria. The material model is implemented in a time-harmonic finite element model, which allows to solve for the loss characteristics of electromagnetic devices. Identification is based on measured hysteresis loops and no additional fitting parameters are required. Hysteresis losses in a ferromagnetic C-core and a ferromagnetic torus are simulated and compared to the results obtained by means of tabulated loss characteristics.</abstract>

    <title language="eng">Consideration of the influence of manufacturing tolerances in the design process of electrical machines using the example of a permanent magnet synchronous machine</title>
    <abstract language="eng">The production process of electrical machines is subject to manufacturing and material tolerances. These tolerances have an influence on both, the mean torque and the torque ripple. Consequently, they exert an active influence on the speed-torque map (operating points), as well as the equivalent circuit diagram parameters for a permanent magnet synchronous machine, and the operational behavior (efficiency, noise development) of the electrical machine. In addition to striving lower costs, there is a growing emphasis on achieving higher energy efficiency. Thus, an accurate prediction of machine parameters is still essential during the early development process, despite manufacturing-related deviations. &#13;
In this study, the prediction of machine parameters is demonstrated using the example of a PMSM.</abstract>

    <title language="deu">PyEMMO - a Python based software for the finite element modelling of electrical machines in ONELAB</title>
    <abstract language="eng">Multi-objective optimizations are almost essential in the design process of electrical machines due to constantly increasing requirements for efficiency and power density. In this context, open-source simulation software offers the possibility to parallelize calculations free of license costs and thus to achieve a reduced calculation time. This paper presents the software project PyEMMO (Python Electrical Machine Modeling in ONELAB) for the finite element simulation of electrical machines in the open source program ONELAB. The object-oriented program structure and the objectives of the project are the main focus. Furthermore, the latest features are discussed, which include the geometry definition via a toolbox system, the simulation data interface based on the JSON file format and the calculation of iron losses.</abstract>
    <abstract language="deu">Multizieloptimierungen sind im Designprozess elektrischer Maschinen aufgrund stetig steigender Anforderungen an Wirkungsgrad und Leistungsdichte nahezu unabdingbar. Dabei bietet Open-Source Simulationssoftware die Möglichkeit lizenzkostenfrei Berechnungen zu parallelisieren und somit eine reduzierte Berechnungszeit zu erreichen. Dieser Beitrag stellt das hierfür initiierte Softwareprojekt PyEMMO (Python Electrical Machine Modeling in ONELAB) für die Finite-Elemente-Simulation elektrischer Maschinen im Open-Source-Programm ONELAB vor. Die objektorientierte Programmstruktur und die Ziele des Projekts stehen hierbei im Vordergrund. Des Weiteren wird auf den aktuellen Funktionsumfang eingegangen, welcher unter anderem die Geometriedefinition über ein Baukastensystem, das Simulationsdateninterface basierend auf dem JSON-Dateiformat und die Berechnung der Eisenverluste beinhaltet.</abstract>
