“…In the second place, LAM11 is a good alternative which is compatible with the highest number of magnets. It is also clear that certain materials have completely failed to fulfill the criterial, such as LAM (8,10), MAG(1, 13,14). It is also important to note that some LAMMAT have very limited options in the PMs.…”

The art of the successful design of high-speed electrical machines comes with many challenges in the mass, size, reliability, and energy efficiency. Material engineering of electrical machines has been identified as a key solution for higher power dense electric drivetrains. One of the main challenges at high speed is the eddy-current losses in the active electromagnetic parts, especially magnetic materials and permanent magnets (PMs). This study is devoted to the selection of PM rotor materials using multidisciplinary design optimization for a high-speed electric drivetrain. Beside AC loss minimization, more disciplines are considered, such as the minimization of weight, and cost. Different laminations are investigated with different magnetic properties as well as cost. Additionally, different PMs are optimized considering low-cost ferrite and high-coercivity permanent magnets (HCPMs). Moreover, the optimal materials are identified which have the best balance between loss, weight, cost, ripples. Finally, different rotor designs are prototyped, assembled, and tested using the same stator configuration. Also, the best rotor design is selected, and the electromagnetic performance is measured and compared with conventional designs. The optimal design results in 8% extra torque with at least 20% weight reduction.

“…Nowadays, the simulation and design of electric machines are performed mostly by using FE methods. The accuracy of a FE model of an electric machine is directly dependent on the identification parameters, such as the material properties [33, 34]. In this work, the proposed method of considering the cutting effect is implemented on a 2D FE model of a permanent magnet synchronous motor (PMSM) using a commercial software package [35].…”

Experimental measurements of electrical machine performances reveal a significant difference between simulations and measurements. It is known that the manufacturing processes of machines, particularly, the cutting of core laminations adversely affects material properties. The current techniques for considering the effects of cutting lack accuracy, computation efficiency and applicability for finite element (FE) software. This study proposes a method to model the variation in the magnetic properties of electrical steel due to cutting based on a non‐equal multi‐slice technique. In this work, the method has been validated and implemented on a FE permanent magnet synchronous motor model. Also, the proposed method has been compared with the single‐layer method.

“…Because the development of field mathematical models is theoretically and algorithmically complicated, the practical statement of the task can be simplified using a simultaneous application of the principles of both the theories of electromagnetic circuits and electromagnetic field in models for the calculation of electromagnetic processes in electrodynamical devices. This approach allows for a description of electromagnetic phenomena in bulky electrical pathways and in magnetic cores using the theory of electromagnetic field and in electric windings using the theory of electromagnetic circuits [11][12][13][14][15] . One of the most prospective trends of creating mathematical models is the sole use of the theory of electromagnetic field for the analysis of electromagnetic phenomena in movable and immovable media of electrodynamical devices [16][17][18][19][20] .…”

In the course of designing and developing different-purpose electrodynamical devices, electromagnetic processes in movable and immovable media need to be calculated simultaneously. The solution for such tasks based on the electromagnetic field theory is associated with the emergence of significant theoretical and practical difficulties. The problems that arise during the calculation of electromagnetic processes in movable and immovable media of electrodynamical devices using the electromagnetic field theory are examined in this study. Improved approaches toward the calculation of electromagnetic processes in electrodynamical devices using Maxwell's equations are suggested. Notably, calculating electromagnetic processes in movable and immovable media using Maxwell's equations necessitates consideration of the systems of coordinates where the electromagnetic phenomena are analyzed. Theoretically substantiated methods of calculating electromagnetic processes in movable and immovable media based on the principles of electromagnetic field theory are proposed. The methods consider the systems of coordinates where the analysis of electromagnetic phenomena is conducted. The effectiveness of the suggested methods for example in calculating electromagnetic processes in movable and immovable media of the turbogenerator is illustrated.
