Application of Digital Twins Technology for Analysis of Brushless Electric Machines with Axial Magnetic Flux

A new class of brushless electric machines with axial magnetic flux (BMAF) is actively developing for small and medium-power drives. Firstly, they had special and military applications, but now they are widely used in industry. This type of electrical machines becomes competitive with traditional electric machines. Practice makes us develop systems for the optimal design of this class of electrical machines. The Department of Theoretical Fundamentals of Electrotechnology, SUSU, developed a software package for the design of various types of the BMAF, which implements multi-level optimization, analysis of magnetic and thermal fields, solid 3D models, analysis of circuit solutions. The developed complex is a professional design tool, which have to be included in a larger system of end-to-end design system for machines of this class. It allows solving complex tasks for different project situations. Structurally, it consists of two parts. It is a synthesis system and an analysis system. The synthesis system implements the creation of optimal geometry. The analysis system is based on the technology of digital twins. The digital copy of the electric machine is created using the finite element method. This model is used to assess the magnetic and thermal state and correctness of circuit solutions. This article presents the analysis system.
