TL;DR: A general middle complexity model of electromagnetic devices is applied to a cage induction motor proposing a simplified representation exploiting the symmetry of the cage itself and a comparative analysis vs the results provided by a finite element model is presented.

TL;DR: In this article, an analytical model (AM) of slotless open-circuit air-gap magnetic field (OC-AG-MF) of IPMSM with V-shaped segmented skewed poles is derived by combining the subdomain method (SDM) and the magnetic equivalent circuit (MEC) method, and then, the AM of slotted OC-AG -MF of IC with V shaped segmented skew poles is obtained by introducing the complex relative permeance.

TL;DR: In this paper , a case study of turboprop mild hybridization using a recently developed integrated drive system in the University of Nottingham, UK, within the ACHIEVE project under EU H2020 CleanSky 2 program (project No. 737814).

TL;DR: The complex rotor structure of synchronous reluctance machines causes a high harmonic content in the air-gap flux density and then flux density fluctuations in different iron parts, which causes a field weakening operation to extend the speed range of the motors.

TL;DR: A generalized modeling approach, based on the saliency ratio, is presented in detail to analytically evaluate the magnetic behavior of the scaled SynRel machines.
