EN 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 fan drive unit. Numerical models of the coreless PMSM in 2D and 3D space were developed. Optimization calculations were carried out using the field model of the machine. Multistage calculations were performed using the author's proprietary FEM code as well as the professional FEM package, ANSYS Maxwell. 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 built prototype motor was subjected to measurement for verification of developed models and proposed design approach exploiting finite element analysis (FEA).
