Modeling of an axial-flux interior PMs machine for an automotive application using magnetic equivalent circuit

Investigation of Volumic Permanent-Magnet Eddy-Current Losses in Multi-Phase Synchronous Machines from Hybrid Multi-Layer Model

“…The semi-analytical model includes the automatic mesh of static/moving zones, the saturation effect and zones connection in accordance with rotor motion based on a new approach called "Air-gap sliding line technic". This technique was applied in [23][24][25][26] on different electrical machine configurations, viz., axial-flux interior PM machine [23,24], coaxial magnetic gear equipped with surface-mounted PMs [25], wound-rotor synchronous machine [27], and radial-flux interior PM machine [26]. This novel technique of connection between static/moving zones as well as the approach proposed in [22] is applied for the first time on a radial-flux surface-mounted PMSM having multi-phases for automotive application.…”

Iron Losses in Electromagnetic Devices: Nonlinear Adaptive MEC & Dynamic Hysteresis Model

“…For the electrical machines, it includes the automatic mesh of static/moving zones, the saturation effect, and the connection of the zones for the rotor motion (which is ensured by a new approach called "Air-gap sliding-line technic"). This generalized semi-analytical model has been applied to an axial-/radial-flux interior PMSM [46][47][48] and a coaxial magnetic gear equipped with surface-mounted PMs [49].…”

Analysis and Design of an Axial Flux Permanent Magnet Motor for in-Wheel System Using a Novel Analytical Method Combined With a Numerical Method

“…In the case of a motor, the magnetic saturation effect is likely to occur in the stator core, and it is a factor that can significantly reduce the performance of the machine, so it must be considered [37]. To consider this, various methods for inducing the relative permeability of the iron core by approximation and interpolation of the B-H relationship, based on the B-H curve characteristic data of the iron core material, have been proposed [38]- [43]. In this paper, a method to calculate the relative permeability function using a piecewise cubic Hermite interpolating polynomial (PCHIP), based on the B-H curve data, is proposed, as is a novel stator core permeability correction algorithm applicable to the proposed MEC.…”
