“…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.…”

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.

“…Consequently, direct‐drive turbines are becoming more popular. Owing to the elimination of gearbox, direct‐drive wind turbines (DDWTs) offer higher reliability, lower maintenance cost, and higher efficiency in comparison with the geared ones [1, 2]. However, due to the lower speed of DDWTs, the generator of these types of turbines must be designed with high torque density value to reduce the generator volume and weight, resulting in the lower cost of the generator and turbine tower structure [3–5].…”

Axial flux permanent magnet machines (AFPMs) are potential candidates for direct‐drive wind turbines (DDWTs) due to offering high value of torque density. In slotless AFPM topologies, the cogging torque is absent which makes them more suitable for DDWTs, which provides an easier turbine start‐up. In this research, a robust design and optimisation procedure of a slotless double‐sided AFPM is discussed. The non‐linear magnetic equivalent circuit is established and the optimisation is performed by the response surface methodology to achieve a cost‐effective generator with high power density value. The generator is prototyped and the test results are presented comparing them with the numerical study and non‐optimised design results. To minimise the AFPM torque ripple which is necessary for DDWT application, a cost‐effective solution is proposed leading to a dramatic improvement in the AFPM torque ripple without reducing the average torque.

“…The MEC method is used to analyze the characteristics of the model by simplifying the structure of the motor to be designed into a magnetic circuit form. The MEC modeling used in this study was proposed in [32]- [36]. However, in [32]- [36], the MEC modeling was conducted under the assumption that magnetic saturation did not occur.…”

“…The MEC modeling used in this study was proposed in [32]- [36]. However, in [32]- [36], the MEC modeling was conducted under the assumption that magnetic saturation did not occur. Because the magnetic saturation of the AFPM motor mainly occurs in the stator, this paper proposes a novel MEC that adds a stator core reluctance to address this.…”
