When designing permanent magnet synchronous machines (PMSM) the losses in the permanent magnets may not be neglected. Especially in high-speed applications these losses contribute a proportion of the total losses which can be significant. In literature existing analytical loss calculation approaches are generally validated by numerical Finite Element Method (FEM) simulations and, however, have hardly been verified by experimental measurements. In this paper the eddy current losses of permanent magnets are investigated by an analytical loss calculation approach which is verified by FEM computations. Furthermore, the results are validated by a measuring setup which determines the AC loss in permanent magnets by a double coil measuring arrangement. The relative conductivity of the permanent magnet is an uncertain parameter for eddy current loss calculations. Therefore it is determined metrologically. The measuring arrangement which is used for this purpose is introduced. As a result important conclusions regarding the calculation and measurement of AC losses in permanent magnets are achieved.

Holistic production optimizations within large-scale productions are not yet used because classic methods like Six Sigma or DoE are less expedient when it comes to huge or more complex data sets. Thus no standardized analysis for integrated production optimization exists, to realize 0 ppm defects. This paper introduces a holistic analytics approach using data mining techniques to reduce the error and scrap rate, addressing experts and non-specialized workers.

High power density and efficiency are key factors for automotive traction machines. One possible way to reach these goals is to increase the slot filling factor. As yet, most research has either been focused on optimizing the slot geometry with a given magnet wire diameter or on finding the optimal diameter for a given geometry. Oftentimes the submitted results lead either to a magnetically suboptimal stator geometry or the suggested winding pattern and geometries are not producible. The introduction of the needle winding technology, as an alternative to the insertion technology for the manufacturing of stators of automotive traction machines, enabled a defined wire placement in the slot. To use the full benefit of this advantage an optimal and producible winding layout is necessary. Therefore, in this article new optimization algorithms are proposed and compared to algorithms found in literature with regard to reachable slot filling factors and producibility. In a case study, the best performing algorithm was used to obtain an optimal combination of wire diameter and slot geometry to maximize the filling factor. With the proposed algorithm feasible winding patterns and slot geometries with an optimized filling factor can be obtained.

Additive Manufacturing (AM), also known as 3D printing, is a relatively new technology which enables the toolless production of components and entire assemblies directly from a CAD file. Today, the technology is still not widely used in industrial production. It is mainly limited to special applications, although it shows great potential. In this paper, first approaches are shown to apply AM to the production of rotors for permanent magnet synchronous machines (PMSM). The possibilities of a lightweight design with a low moment of inertia as well as the influence on the magnetic anisotropy for an improved sensorless control of PMSM are pointed out. The results clearly demonstrate the great potential of additive manufacturing in electrical engineering applications.

Various manufacturing processes in the production - from laminated magnetic steel sheets to an assembled stator - affect the electromagnetic characteristics. Often the manufacturing processes of the process step cutting are compared to highlight differences. Many publications have already dealt with this issue over several decades. Flux distribution, loss and the B-H characteristics are not the same, whether an electrical sheet with defined geometry is cut with a laser, water jet, electrical discharge machining, rotational cutting or with a punching machine. It is adequately researched that differences in loss behavior occur. Within the various technologies, a comparison of varied production parameters is scarcer. Here, interesting studies result when considering the specific hysteresis and eddy current losses in the variation of the process parameters on the relative position of the rolling direction, average speed, distance energy and the comparison between fiber and CO2-Laser with different focus diameters. This paper deals with the comparison of cut sheets made from electrical steel with grade M270 35A. The metal strips investigated were prepared on dimensions of 150×150 mm and 37,5×150 mm using the above parameter variation and analyzed in a single sheet tester from Brockhaus regarding their loss behavior.

The fundamental control design aspects for synchronous reluctance motors without damper circuit are discussed in this paper. To achieve a high control performance and the quality demanded in industrial environments, the impact of the motor's typical nonlinearity with respect to the control structure required is considered. Based on measured saturation characteristics, a state-space model is derived for further observer design as well as for simulating the system. Control strategies with optimum efficiency are calculated and compared. Controlling the motor at defined current- and voltage limits is an essential feature of industrial drives, and is described in detail. Finally, the last section presents a powerful method for identifying the initial rotor speed and -position for starting and for flying restarts without an encoder.

Axial mechanical stress on electrical steel significantly affects the magnetic properties of electric steel. The magnetizability is reduced and the losses are increased. In electrical machines, axial mechanical stress is induced in different processes of production. The lamination stacks are often compressed by means of axial pressure to create a compact and robust magnetic core. This work focuses on the influence of axial pressure on the rotor lamination stack from a new low cost rotor assembly. A setup is constructed to measure the influence of axial mechanical pressure on the magnetic properties of ring core samples made of electric steel. Extensive measurements at different values of axial mechanical pressure are conducted. From the measured data, an iron loss model is parametrized. The influence of axial mechanical pressure on the hysteresis losses and the eddy current losses is discussed. The identified loss model parameters are applied to the solution of a 2D FEM simulation of the permanent magnet synchronous machine. The influence on the loss characteristics of the machine is studied.

Parts of electric motors and transformers are composed of sheet-layered lamination stacks, which heavily influence the mechanical properties of such devices. Especially the interaction of individual sheets by direct contact or the presence of bonding varnish may cause a nonlinear deformation behavior such that these effects have to be included in a FE-simulation. Here, homogenization techniques are presented to ensure computational efficiency by avoiding a full numerical simulation with every single sheet and to cover simultaneously the real physical behavior by identifying a linearized transversely isotropic surrogate material model. During this homogenization process, the interlayer between two sheets is incorporated by Zero-Thickness elements.

The market-entry strategy of a highly innovative product, such as an electric in-wheel drive for light electric vehicle applications, is best supported with a profound knowledge of these emerging markets. The focus of this article lies on the market analysis respectively the market forecast. The electric scooter market in Western Europe is chosen in a case study to illustrate the use of a proposed methodology to forecast scenarios for sales growth rates and sales volumes. The suggested approach is one element of an overall assessment of the global market for electric light vehicles, which also includes definition of client and user profiles, the identification of competing powertrain technologies to the evaluation of current and potential sales channels and structures. Together, these elements will serve as a basis for developing a comprehensive marketing and commercialization strategy for a small organization that develops innovative electric in-wheel motors.

As the efficiency of electric power trains in hybrid electric vehicles should be increased and at the same time the manufacturing costs reduced, different motor designs and production concepts need to be considered. Because of the nearly sinusoidal magnetic field inside, the stator design with distributed windings, which is typically produced with the insert technique, is technically preferred. The insert technique offers a high productivity because the complete winding assembling process can be done in one step. This results in the fact, that nearly 80% of all electric motors worldwide have distributed windings. In order to enhance the possibilities for distributed windings with the insert technique, the current fill factor needs to be improved. Due to the fact that the actual wire placement cannot be measured und thus not optimized, a simulative approach with a multi-body simulation is used to understand the process interactions between the wires, the stator groove and the tool. This approach will be presented in this paper.
