“…All of the aforementioned advantages have increased the interest of both industry and academia towards the adoption of printed circuit boards for the design of non-conventional electrical machines. In [20], a prototype of an integrated motor-pump structure made of an axial flux PM machine with PCB windings is built and tested; in that arrangement and with a very limited volume, a vortex type impeller is located on the magnet periphery and the fluid flow is controlled by adjusting the motor speed. An axial flux single phase iron-less PM generator with PCB stator is proposed in [21], with the aim of developing a zero cogging torque solution for small marine energy conversion systems.…”

This work is focused on the design optimization of electrical machines that are used in small-scale direct-drive aerogenerators. A ducted wind turbine, equipped with a diffuser, is considered due to its enhanced power capability with respect to bare turbines. An annular type Permanent Magnet brushless generator is integrated in the turbine structure: the stator coils are placed in the internal part of the diffuser, whereas the permanent magnets are on an external ring connected to the turbine blade tips. Moreover, as regards the stator windings, the Printed Circuit Board (PCB) technology is investigated in order to exploit its advantages with respect to conventional wire coils, such as the increased current density capacity, the reduction of costs, and the enhanced precision and repeatability of the PCBs. An original design procedure is presented together with some scalability rules. An automated tool has been developed in order to aid the electrical machine designer in the first design stages: the tool performs multi-objective optimizations (using the Matlab Genetic Algorithm Toolbox), coupled to fast Finite Element analysis (through the open-source software FEMM) for the evaluation of the electromagnetic torque and field distribution. The proposed procedure is applied to the design of an annular PM generator directly coupled to a small-scale turbine for an urban application.

“…With the advance in permanent magnet technology nowadays, permanent magnet has been preferred in developing axial flux synchronous machines. There have been more and more interests in AFPM machine in the recent years, their noticeable applications include: generators for wind systems [117][118][119][120][121], electric vehicles [122][123][124][125], pumps, heating gen-sets, machine tools and robots [126][127][128][129][130][131][132]. The AFPM machine is an attractive alternative to the conventional radial flux type due to its pancake shape, compact construction and high power density [8,9,133,134].…”

Summary In this paper, design and prototyping of two‐speed capacitor‐run single‐phase axial‐flux induction motor (AFIM) for direct‐drive applications is presented. The proposed structure has single stator‐single rotor configuration with high magnetic pull between the stator and rotor, which may compel rotor to lock. Although the most efficient method to overcome this problem is using a second rotor or stator in the mirror with the first one, it is not applicable in low‐cost applications. So, in this paper, two new and fast construction techniques are proposed to fabricate an AFIM with extra low air‐gap length and minimum cost. Beside design and optimization process, a thermal equivalent circuit considering radial and lateral heat transfers is proposed. Then different losses and thermal resistances are exactly calculated to estimate the temperature rise of different motor parts and the maximum specific magnetic and electric loadings. Then, motor performance is evaluated using three‐dimensional time‐stepping finite‐element analysis. Finally, a comprehensive fabrication algorithm for AFIMs is presented, and a prototype of the studied motor is fabricated and tested. The experimental results validate the design, optimization, thermal model, and finite element simulations. Copyright © 2016 John Wiley & Sons, Ltd.
