“…Therefore, this method is utilized in several publications (e.g. in [60], [158], [183], [185], [193], [237], [253], [255], [270]- [280]). With this calculation, leakage flux is investigated [163] and the influence of nonlinear and anisotropic properties of the material is considered [237], thereby receiving results with good accordance on measurements.…”

For applications with high torque demand, gearboxes are commonly used to convert torque and speed in order to receive higher specific values for torque and power. This causes additional losses, cost, inaccuracies, effort, and noise. Eliminating the need of a mechanical gear and the associated disadvantages, Transverse Flux Machines with their high torque density are a very promising alternative. Despite a high torque density and a good efficiency, these types of machines are not commonly used. Due to the complex structure, challenges with mechanical design, and modeling of the machine behavior arise. Additionally, there are high requirements for the inverter due to the low power factor. This paper provides an overview of the state of the art including the potentials and advantages but also the problems and hindrances of these types of machines. Relating to linear and rotary machines from research and industry, the machine is introduced with its history, application and classification. Further, the general technical aspects, the influence of materials for flux guidance, the methods of modeling, methods for a minimization of torque ripples, as well as methods for power factor improvement are presented.

Transverse flux permanent magnet (TFPM) machines are a potential candidate for directdrive wind power application due to high torque and power densities. The operating principle of TFPM machines is firstly described with various topologies available in literature, with the placement of magnets as a criterion for the classification of TFPM machine topologies. This review includes characteristics, power factor improvement, cogging torque minimization, material consideration, modelling techniques, and scalability. Different wind turbine concepts with direct-drive machines, control techniques and power converter topologies are also considered in this paper. INDEX Permanent magnet, topologies, transverse flux, and wind power.

“…Iron losses are of key importance since they affect the design of electrical machines. In the last five years researches have been performed [1]- [3] in order to propose new iron losses models; they are compared with existing ones. In [1] the prediction of excess loss from three models were compared: two models on frequency domain and third one in time domain.…”
