## 1 Introduction  
Electric motors are critical components in a variety of industrial applications, including electric vehicles, robotics, and aerospace systems. The development of efficient and accurate computer-aided design (CAD) models for electric motors is therefore essential for the design, analysis, and optimization of these systems. In recent years, considerable research effort has been dedicated to the development of CAD models for electric motors. Induction motors (IM) have gained popularity in robot and arm drives due to their high reliability, low cost, and lack of permanent magnets [1]. The Induction Machines Handbook [2] offers a practical and up-to-date treatment of complex issues related to IM necessary for design and testing in both constant and variable-speed drives (with power electronics). It contains industrial design and testing knowledge with numerous case studies to aid in the assimilation of new knowledge. Advanced issues and subjects in electric machines are extensively covered in the book [3] from principles to applications and case studies, with ample graphical and numerical results. The latest knowledge with strong industrialization potential has been added to this edition, including orthogonal models of multiphase AC machines and thermal finite element analysis of electric machines. The monograph [4] provides an up-to-date overview of numerical field computational methods and, in particular, of the finite element method (FEM). Particular attention is paid to the practical use of the FEM in designing electric motors. The monograph [5] describes promising technology with MATLAB/SIMULINK in electrical machines, addressing the concept of electromechanical energy conversion and exploring various electrical machines, special electrical machines, electrical drives, and their applications using MATLAB/SIMULINK. It also provides a condensed and extensive review of current trends and outcomes with the ultimate goal of emphasizing energy conversion and up-to-date electrical applications for engineering students. Engineering analysis is a crucial aspect of modern investigations, and a correctly constructed CAD model is the basis for such analysis [6; 7; 8; 9]. CAD/CAM systems are widely used for computer simulation of products with complex shapes, design documentation, generation of control programs for CNC machines, or internal research to determine product parameters before release [10; 11]. Some of the commonly used CAD systems include AutoCAD, SolidWorks, Pro/Engineer, and Unigraphics [12]; however, specialized packages of numerical modeling lack advanced facilities for engineering analysis. CAE systems such as Abaqus, Ansys, COSMOS, and Nastran enable qualitative simulation of systems of different physical natures and the study of their response to various external influences, including stress distribution, temperature, velocity, and electromagnetic fields [13; 14]. Using such software helps determine various parameters of the object under study before developing the first prototypes, ultimately eliminating defects at the development stage and reducing the development cycle [15]. The study [16] is aimed at a static and dynamic simulation and optimization approach for an induction motor. The model is validated using experimental data and shows good agreement with the measured results. Another digital simulation model of motor drive is [17]. The model is shown to provide accurate results for both steady-state and transient analyses. Based on such results, hybrid CAD models for synchronous reluctance motors that combine a magnetic equivalent circuit models with a finite element model are validated using experimental data showing good agreement with the measured results. A computational model analyzing dynamic response of an induction motor stability under load was presented in [18]. The model is validated using both simulation and experimental data and shows good agreement with the measured results.
