“…These materials provide an excellent understanding of the main types of electrical machines and explain the conceptual issues regarding electrical machine design, e.g., modeling leakage flux and taking into account the winding factor. Additionally, there are quite a lot of papers about this subject [5][6][7][8][9][10][11][12]. Nevertheless, most of these papers are focused on analysis, presenting the results and the advantages of a designed machine.…”

A Step-by-Step Procedure to Perform Preliminary Designs of Salient-Pole Synchronous Generators

This paper presents a straightforward step-by-step procedure to design salient-pole synchronous generators, starting with its main specifications and finishing with all necessary data to put it on production. As most of the electricity is generated by synchronous generators, the design of these machines remains an interesting subject, but, although it is important, it is difficult to find a complete step-by-step procedure in the literature. The proposed procedure can be followed by an electrical engineer or student and, distinctively from most papers and books, all steps are presented. Such a procedure is based on analytic calculations, eventually relying on finite element simulation to verify if everything is all right and to adjust some design parameters. All calculations have been chosen to keep the design as simple as possible; otherwise, it would not be possible to present all steps and procedures. Therefore, it can be used for beginners in the art of design-synchronous generators, applied to obtain an initial design, or be adopted by any electrical engineering course, not only aiming to be an introductory electrical machine design course but mainly to enhance the students’ comprehension of synchronous machines. The results have been compared with finite element simulation, presenting very small differences.

“…After the electrically switching excitation circuit invention 8 , the EESM is revived as a promising candidate for further development. Limited works highlight their capabilities 9 – 12 for traction applications. The prime benefits of this topology are: (i) cost-effective, the total elimination of magnets which makes EESM much cheaper than other topologies using magnets (e.g.…”

“…They invented a switching exciter circuit in the side of the rotor winding to transfer current from the power supply to the rotor of the EESMs. A few researchers investigated the analytical modelling of EESMs 9 , in which they studied a formalized method to calculate the field distribution and dq -axis model parameters. In another work 10 , the researchers proposed a low-order lumped parameter thermal network to predict the temperature rise of the EESMs, in which thermal resistances and capacities were identified individually.…”

A physics-informed Bayesian optimization method for rapid development of electrical machines

Advanced slot and winding designs are imperative to create future high performance electrical machines (EM). As a result, the development of methods to design and improve slot filling factor (SFF) has attracted considerable research. Recent developments in manufacturing processes, such as additive manufacturing and alternative materials, has also highlighted a need for novel high-fidelity design techniques to develop high performance complex geometries and topologies. This study therefore introduces a novel physics-informed machine learning (PIML) design optimization process for improving SFF in traction electrical machines used in electric vehicles. A maximum entropy sampling algorithm (MESA) is used to seed a physics-informed Bayesian optimization (PIBO) algorithm, where the target function and its approximations are produced by Gaussian processes (GP)s. The proposed PIBO-MESA is coupled with a 2D finite element model (FEM) to perform a GP-based surrogate and provide the first demonstration of the optimal combination of complex design variables for an electrical machine. Significant computational gains were achieved using the new PIBO-MESA approach, which is 45% faster than existing stochastic methods, such as the non-dominated sorting genetic algorithm II (NSGA-II). The FEM results confirm that the new design optimization process and keystone shaped wires lead to a higher SFF (i.e. by 20%) and electromagnetic improvements (e.g. maximum torque by 12%) with similar resistivity. The newly developed PIBO-MESA design optimization process therefore presents significant benefits in the design of high-performance electric machines, with reduced development time and costs.

“…Therefore in power electronic design optimisation, modelling usually comes down to one or a set of algebraic (or, in rare cases, differential or integral) equations which are much easier to evaluate in a computation‐intensive optimisation problem. It should be mentioned that in some areas such as electrical machines, it is now a common practice to use complex finite element models [7, 8] or complex MATLAB models [9–12] for optimisation; however, use of these complex models are very limited in power electronics.…”

Design optimisation techniques for power electronic converters have been the subject of numerous research studies for the past 15 years. Accurate modelling is the most important task in the optimisation, and, because the nature of optimisation problem demands evaluating an objective function numerous times, fast and simplified modelling techniques are required. The objective of this study is to categorise and analyse the previous studies related to modelling techniques incorporated in design optimisation of power electronic converters. Common trends in modelling and optimisation of power electronic converters are analysed and suggestions for future research in this field will be presented.
