“…Moreover, because the arrangement of permanent magnets is irrational, the magnetic force of permanent magnets is not well utilized. However, the Halbach array has been widely used as a permanent magnet arrangement that achieves high magnetic field strength in specific directions [19,20]. In recent years, the application of Halbach arrays in permanent magnet motors has become a research hotspot, such as in permanent disk motors [21], permanent magnet linear motors [22], permanent magnet vernier motors [23], and so on.…”

Permanent magnet-assisted synchronous reluctance motors (PMA-SynRMs) are widely used in various industries as a relatively inexpensive and high-performance energy conversion device. The model proposed in this article relies on a magnetic pole-biased permanent magnet synchronous reluctance motor with a magnetic focusing effect. Two types of models with Halbach array and magnetic focusing effect have been proposed, which increase excitation and make the internal magnetic circuit of the rotor more saturated, thereby achieving higher electromagnetic torque. Through finite element simulation analysis and verification, the motor characteristics of the basic and proposed permanent magnet-assisted synchronous reluctance motor were calculated, including the air gap flux density and back electromotive force (EMF) in no-load analysis, as well as the average torque, torque ripple, and efficiency in load analysis. In addition, multi-objective optimization was also conducted on the rotor topology structure of proposed model two, using the uniform Latin hypercube sampling method to uniformly sample the data samples and the Pearson correlation coefficients to perform a sensitivity analysis on the data. The pilOPT multi-objective autonomous optimization algorithm was used to perform multi-objective autonomous optimization on parameters with high correlation, and the best-found solution based on the Pareto front was selected. Compared with proposed model two, the average torque of the optimized model increased by 18.14%, the efficiency increased by 1.05% and the torque ripple decreased by 5.22%. Finally, the anti-demagnetization performance of the optimized model’s permanent magnet was analyzed.

“…Instead, it is enhanced in specific areas and weakened in others. (14)(15)(16)(17)(18)(19)(20) The Halbach magnet array can also concentrate the magnetic field on one side. Besides the benefits of enhanced magnetic force, the reduced magnetic force at the back can minimize interference with other parts, thus reducing the need for magnetic shielding materials and offering linear motor functionality for low-frequency electromagnetic operation.…”

“…NdFeB is a form of the permanent rare-earth magnet with a higher flux density than other types of ferromagnetic magnets. With a small volume, rare-earth permanent magnets can have a high flux density, allowing them to construct high-efficiency machines with minimal power losses and compact materials [11] . NdFeB is a permanent magnet with the maximum flux density.…”

Wind energy conversion system, one of the main components is a Permanent Magnet Synchronous Generator (PMSG). During the past two decades, many types of permanent magnet generators for wind power applications have been the research topic.This study focuses primarily on designing a PMSG to create, simulate, and analyze an internal permanent magnet topology with twelve plots and eight poles. We limit with the simulation was carried out at a rotational speed of 1000rpm, and a type of permanent magnet material, Ceramic 11, SmCo 26/26, and NdFeB 48/11. The result of the analysis is that permanent magnets applied in the design of a generator impact its output power and efficiency. At 15 Ω and 60 Ω loads, SmCo 26/26 and NdFeB 48/11 are the only ones that fulfill the specified requirements in this investigation.The permanent magnet type with the most optimal characteristics is Neodymium Iron Boron 48/11 because it has a high flux density, thus causing the electrical energy generated to be greater than other types of permanent magnets. The 48/11 NdFeB permanent magnet generates the most output power, 2110.86 W when loaded with 15 Ω. The best efficiency of 89.38 percent for the PMSG 12 slot eight poles occurs when the load is 15 on the 48/11 NdFeB permanent magnet.
