“…Most similar approaches focus on active parts design, passive parts and geometries are often neglected, but can have a significant influence on certain optimization objectives (Golovanov et al, 2019). In (Di Nardo et al, 2016) a component specific design is reported for the design of a rotor for a synchronous reluctance motor. Here only parameters of this specific component are considered, thus fixing parameters of other machine components, e.g.…”

This paper presents a systematic approach to multidisciplinary design automation in electric motor engineering, focusing on component design. Existing work in this field is often limited to a single level and lacks portability and reusability. The approach aims to enable simultaneous component and system design, with comprehensive models capturing specifications and architecture. Feasibility is demonstrated through the automated design of additive manufactured hairpin windings.

“…Since this form of geometry simplification is limited when dealing with more complex geometries, FEA calculations tend to be used for this purpose in the reviewed papers. Thus, there are a variety of papers that use 2D FEA simulations to evaluate detailed rotor geometries in synchronous reluctance machines [44,68,83] and permanent magnet-excited machines [22,43,66,84]. For the design of high-speed rotors that include retention sleeves, 2D FEA is also utilized [50,60].…”

“…Reference [104] presents and compares different architectures of coupled electromagnetic and mechanical analyses. Reference [83] suggests a parameter-split decoupling (PSD) approach, where the design parameters of a SynRM rotor are split into two subsets. One subset will be part of the electromagnetic analysis, with the other being fixed, and vice versa for the structural analysis.…”

Electric motor development is a challenging task, as higher efficiency requirements and various interdependencies between different engineering domains must be considered. Established design approaches often lack the ability to address these interdependencies because they focus on specific domains and properties. Automated, multidisciplinary design approaches hold untapped potential for optimizing motors in terms of diverse requirements and advancing the development of more efficient and reliable motors. This paper presents a systematic literature review of the current state of research in the multidisciplinary design automation of electric motors. The literature basis comprises 1005 publications that are identified by a systematic internet search. The review of the existing approaches is based on twelve criteria that characterize the design automation task in general, such as knowledge representation or reasoning methods used, as well as criteria specific to electric motor design, such as domains considered and their coupling. The analysis reveals what current approaches are lacking: Consequent analysis and integration of domains, applicability of suggested methods, incorporation of established multidisciplinary design optimization (MDO) architectures, alongside the consideration of passive components in the motor. Aside from the introduction of twelve criteria for systematic charaterization of multidisciplinary design automation of electric motors, this article expands the state of the art by proposing an initial framework to establish process chains tackling the identified gaps in the review.

“…The location and distribution of the iron ribs along the barriers need to be optimized keeping the total iron bridge thickness per barrier as close as possible to the analytical estimated values. By doing so, the average torque would not change being not affected by the ribs position along the barrier but mainly by their thickness [32].…”

An important barrier to the adoption and acceptance of synchronous reluctance (SyR) machines in different applications lies in their non-standardized design procedure. The conflicting requirements incurring at high speeds among electromagnetic torque and structural and thermal limitations can significantly influence the machine performance, leading to a real design challenge. Analytical models used for design purpose lack in accuracy and force the designer to heavily rely on finite element analysis (FEA), at least during the design refinement stage. This becomes even more computationally expensive as the speed increases, as the evaluation of the rotor structural behaviour is required. This work presents a computationally efficient hybrid analytical-FE design process able to consider all the main limiting design aspects of SyR machine incurring at high speed, namely structural and thermal. As a vessel to investigate the proposed design routine accuracy, several high speed SyR machines have been designed for a wide range of operational speeds (up to 70krpm). The thermal and mechanical factors limiting the high speed operation are deeply analyzed aiming at maximize the mechanical output power. The proposed design approach is then validated by comparison against experimental measurements on a 5kW-50krpm SyR prototype. Index Terms-Analytical design, finite element analysis, high speed, iron bridges, iron losses, structural rotor design, synchronous reluctance machines.
