“…10 (b). The magnetic resistance caused by the axial leakage resistance flux can be calculated using the following equations [21], [22], [23], [24], [25], [26]. As PM 1 and PM 2 have different magnet types, the magnetic resistance corresponding to axial leakage is expressed as R ma_PM 1 and R ma_PM 2 , respectively.…”

In this study, we propose a novel analysis method for a spoke-type permanent magnet (PM) synchronous motor (PMSM) using two types of PMs that consider axial leakage flux using a magnetic equivalent circuit (MEC). Spoke-type ferrite PMSM have the advantage of concentrating magnetic flux; however owing to the shape in which the PMs are arranged along the radial direction, some magnetic flux leaks in the axial direction, which causes inconsistency between the 2D and 3D finite element analysis (FEA) results. Because 3D FEA requires considerable analysis time, using it in the initial design stage of the motor is inefficient. Therefore, we present a new analytical method combined with MEC to overcome the existing inefficient approach. To obtain analysis results equivalent to 3D FEA, the new residual magnetic flux density considering axial flux leakage was applied to 2D FEA PMs using MEC and 2D FEA. The validity of the proposed method was verified through 3D FEA and experiments conducted on the test models using two magnet types.INDEX TERMS Axial flux leakage, ferrite permanent magnet motor, hybrid magnet, less-rare-earth motor, lumped magnetic equivalent circuit, spoke-type permanent magnet motor.

“…In practice, for the analysis of electromagnetic phenomena in bulky electrical pathways and magnetic cores of electromagnetic devices using principles of the theory of electromagnetic circuits, spatial structures of devices are often replaced using chain equivalent circuits [6][7][8][9][10] . The construction of chain equivalent circuits is based on the formation of conventional magnetic circuits with concentrated parameters (both for individual elements and the entire device).…”

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.
