.... This is the situation where applications require a high speed. The most significant applications in this category are electrical propulsion and drive systems. Design/methodology/approach An analytical model is used to predict the AC losses in the winding of electrical machines. The process involves dividing...

... with the design of an MRI compatible electrical actuator. Three-dimensional electromagnetic and thermal analytical models have been developed to design the actuator. These models have been validated through 3D finite element (FE) computations. The analytical models have been inserted in an optimization procedure...

...Siquan Zhang Purpose In eddy current nondestructive testing, ferrite-cored probes are usually used to detect and locate defects such as cracks and corrosion in conductive materials. However, the generic analytical model for evaluating corrosion in layered conductor using ferrite-cored probe has...

...Minglei Yang; Zaimin Zhong; Qinglong Wang; Zhongshu Shao Purpose The purpose of this study is to propose an analytical model with consideration of the permeability of soft-magnetic materials, which can predict the magnetic field distribution more accurately and facilitate the initial design...

...Zahia Amrouchi; Frederic Messine; Clement Nadal; Mohand Ouanes Purpose In this work, a method to design a slotless permanent magnet machine (SPMM) based on the joint use of an analytical model and deterministic global optimization algorithms is addressed. The purpose of this study is to propose...

...Mohammadreza Baghayipour; Ahmad Darabi; Ali Dastfan Purpose This paper aims to propose an analytical model for the harmonic content no-load magnetic fields and Back electric motive force (EMF) in double-sided TORUS-type non-slotted axial flux permanent magnet (TORUS-NS AFPM) machines with surface...

... permanent magnet synchronous machines, Figure 1 and Table I , with 10-pole/12-slot (denoted as 10p12s) and 12-pole/18-slot (denoted as 12p18s) are analysed with FEM in this paper. Cogging torque Analytical model Finite element method (FEM) Segmented stator core Surface-mounted permanent magnet...

... for estimating the minor loop iron losses introduced by static convertors. They compared the proposed model with another analytical model (J. Lavers model) for different wave forms. One can observe that the J. Lavers model overestimates the iron losses introduced by the non‐centred minor loops. Originality...

... convergence is not achieved because of a worse choice of the starting point. We note that there is no impact on the CPU‐time if the formulation has more variables than another one. Optimal design Analytical model Formulation Modelling Local optimization Numerical methods Inverse problem Electrical...
