This paper proposes a transverse flux machine which has the topology of flux-concentrating and passive rotor, and also conducts a design and optimisation for machine. With working process of the machine introduced, its topology structure and composition are introduced. The optimisation objectives and design parameters are obtained with analysis. Furthermore, the performance equations are deduced to determine the parameters which affect performance. Ten free parameters should be optimised and the number of pole pair is first optimised with preliminary simulation. Subsequently, Taguchi method is applied to reduce the number of free parameters, and four parameters are selected to be further optimised. Three approximation models are created, and the Kriging model is better to predict the simulation results, thereby substitute the simulation to be used to algorithm. Accordingly, NSGA-II and MOPSO are used to acquire the optimal design for the machine, and the best solution of algorithm is determined by the simulation based on the results from the two algorithms. Finally, the prototype experiment is conducted to verify the optimisation method and simulation. The whole optimisation process for design and optimisation of electrical machine which is timesaving in comparison with optimisation with only simulation can provide the reference for electrical machine's design.

“…TFPMMs are also recognized as modulated pole machines [8,9]. The TFPMM usually has a toroidal armature winding, where the current runs parallel to the direction of rotation [10]. In other words, the plane of the magnetic flux path of a transverse flux machine is perpendicular to the moving direction [11].…”

Abstract:The purpose of this paper is to propose a novel design for the transverse flux permanent magnet (TFPM) disk-rotor generator with E and I-shaped cores (TFPMDEIG). Disk-shape structure increases the machine's power factor, allows for high rotational speeds, decreases centrifugal force over permanent magnets, and is employed in wind turbines, due to its compact structures. As for other advantages for this structure, one can point to the fact that there are as many windings as machine's pole pairs; these windings become parallel by observing the polarity. In other words, the total power of this machine is distributed between pole pairs, increasing the overall reliability of the machine. In this paper, first, the initial design algorithm and the basic formulas governing the behavior of the proposed structure using the equivalent magnetic circuit for each pole are provided, and the three-dimensional finite element method (3D-FEM) is used for verification of the algorithm. To validate the simulation results (3D-FEM), then, a prototype has been fabricated and experienced. The experimental results are in good agreement with simulation results.

“…TFMs are inherently three-dimensional devices that require 3D FEA, which has been the main tool used for the analysis and design of many machines reported in the literature [3], [5]- [9]. By contrast there are significantly fewer papers on analytical methods [10], [11].…”

Abstract-Despite transverse flux machines (TFMs) being intrinsically three-dimensional, it is still possible to model them analytically using relatively simple models. This paper aims to provide an insight into the behaviour of TFMs using a compact equation, which relates torque to the electric and magnetic loadings of the machine and a flux factor. The flux factor is also used to estimate the flux linkage and therefore the power factor of this kind of machines. It is shown that the low power factor of TFMs is not only due to leakage but also due to the nature of the electromagnetic interaction that takes place. The TFM developed at the University of Southampton is used as the basis of a case study to illustrate the trade-off between torque density and power factor, and to provide some design guidelines. The analytical results are verified using finite elements analysis and experimental data.
