“…In addition, a 380 W three-phase prototype is manufactured for validation purposes. A comparison of two flux switching TFPM machines with SMC cores and ferrite magnets is performed in [106]. The difference between d-and q-axis inductances is small and only the PM component contributes to the main torque.…”

“…The PM selection criteria need special consideration in the design process of the TFPM machine for achieving a high power factor with reasonable torque density. In literature, ferrite magnets and rare earth magnets are employed in the design procedure of the TFPM machine [106], [138]. Because of high energy density, the TFPM machine design often requires rare earth magnets (NdFeB or SmCo) for improvement in magnetic loading which leads to a high This work is licensed under a Creative Commons Attribution 4.0 License.…”

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.

“…However, they are very expensive. To decrease the cost of SMC motors, ferrite magnets can be used to replace these expensive NdFeB magnets with a proper design of the motor topology, for example, the flux concentration design [12]. Meanwhile, transverse flux reluctance machine can be designed without the use of any magnets [1,13].…”

This paper uses the Taguchi method to optimize the manufacturing process and robust design of a low-cost permanent magnet motor with soft magnetic composite (SMC) cores. For the manufacturing process, SMC cores are produced by using the molding technology without any wire cutting costs. To maximize the relative permeability and minimize the core loss, the Taguchi method is employed to identify the best control factor values for the heat treatment of SMC cores based on a series of experimental results. Due to the manufacturing tolerances, there are significant uncertainties in the core densities and motor dimensions, which will result in big performance variations for the SMC motors in the batch production. To obtain a robust design less sensitive to these tolerances, the conventional Taguchi parameter design method and a sequential Taguchi optimization method are presented to maximize the average torque and minimize the core loss of a low-cost PM motor. Through comparison, it is found that the proposed optimization method is efficient. It can provide an optimal design with better motor performance and manufacturing quality. The proposed method will benefit the industrial production of cost-effective PM-SMC motors with robust and compact designs.

“…Mechanically, this material can be used to produce magnetic cores by the highly matured powder metallurgic technology, which results in structures with extremely high productivity and low manufacturing costs. Thus, it is believed that SMC is appropriate for higher frequency applications, such as the high speed electrical machines and electrical machines with large numbers of pole pairs [22][23][24].…”

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.
