“…On the other hand, the mass production of classical coils for coreless Energies 2024, 17, 1664 2 of 17 machines from round or profiled copper winding wires requires the use of precision winding machines, special tooling, a complex process of spatial shaping and fixing of coils and impregnation or pouring epoxy resin over the windings. It is important to achieve a high filling factor of the coil side cross-section with copper and to limit eddy currents in the conductors [15][16][17]. Despite these disadvantages, classic windings are still commonly used in many types of coreless electrical machines [18,19].…”

The paper presents a new cost-effective magnetic circuit structure of a coreless permanent magnet synchronous motor (PMSM) with 16 poles and 12 coils for a mass production fan drive unit. 2D and 3D numerical models of the coreless PMSM were developed. Optimisation calculations were carried out using the field model of the machine. Multistage calculations were performed using the professional FEM package, ANSYS Maxwell and the author’s proprietary finite element method (FEM) code. On the basis of the conducted tests and analysis of the obtained results, the “optimal” magnetic circuit structure of the PMSM motor was selected. The prototype motor was subjected to measurement to verify the developed models and the proposed design approach that takes advantage of finite element analysis (FEA).
