Vector Hysteresis Model Associated to FEM in a Hysteresis Motor Modeling

Preisach Hysteresis Model – Some Applications in Electrical Engineering

“…The energy losses can be evaluated by computing the magnetic field and magnetic induction solutions to ( 19)-( 22) with appropriate numerical techniques, such as Finite-Difference Time-Domain (FDTD) [33,34] or Finite-Element method (FEM) (see, for instance [35][36][37][38][39][40][41][42] where scalar and vector hysteresis models are considered, respectively). In particular, we have applied the latter and a fixed-point iteration (see [24], Section 3) and also [43,44] for different fixed point iteratios applied to hysteresis models).…”

Optimal Design of IPMSM for EV Using Subdivided Kriging Multi-Objective Optimization

“…In the paper based on FEM analysis, however, the model is demonstrated indirectly because the reference model of the proposed paper progressed with reference to the [39]. The accuracy of FEM analysis in existing research cases is very high compared to the simulation [40][41][42]. Furthermore, there are many papers that validate the performance of the algorithm with only FEM interpretation [43][44][45][46].…”

Analysis, Design and Optimization of Hysteresis Clutches

“…The first suite [18] uses the model presented in [20], whereas the latter implements the Jiles-Atherton model [21]. Other ways [9]- [11], [14] to determine the hysteresis losses/torque consists in performing the finite element analysis with the single value BH curve and post-processing the magnetic field using hysteresis model, such as Preaich models [22], [23] or Jiles-Atherton model in an iterative fashion. In particular, in [9] a linear finite element analysis is performed initially assuming an arbitrary permeability and magnetization in each element of the hysteresis region.…”

“…In fact, when considering low Fig. 8: Pareto fronts: isotropic case number of poles (10)(11)(12)(13)(14)(15)(16), an increment of the latter always produces an improvement of the performance, i.e. the same torque can be achieved with lower magnet volume or the same overall magnet volume produces more torque.…”

“…Analytical approaches are reported in [7], [8] and they are based on approximations of the problem formulation. Conversely, [9]- [11] propose a numerical method based on finite element analysis and vector hysteresis model, and use an iterative procedure to calculate the hysteresis torque with really high computational burden.…”
