“…In this paper, grain-oriented electrical steel (GO) is applied to an IPMSM to acquire torque improvement. Especially, as the magnetic characteristics of the GO vary according to the angle of the flux, the GO is partially applied to the stator teeth, where the direction of the flux path is uniform, and the effect of the GO can be maximized [17].…”

This paper proposes a method for enhancing the performance of an interior permanent magnet synchronous motor (IPMSM) using grain-oriented electrical steel (GO) and design optimization. As the GO has superior magnetic characteristics in the rolling direction, the GO is applied to the stator teeth to increase the torque and reduce the iron loss of the IPMSM. However, such an approach leads to higher saturation on the core, resulting in worse pulsation characteristics. To handle with pulsation problem on the IPMSM, design optimization is conducted. In this paper, the interpolation multi-objective robust optimization algorithm (IMROA) was proposed. The IMROA can reduce the calculation time by interpolating the objective region and utilizing a stepwise sampling strategy. Moreover, the IMROA considers the robustness of the found solution and can derive a robust global solution that has robustness on the manufacturing tolerance and deformation during the operation and prevents unexpected results on the IPMSM.

Among soft magnetic materials, non-grain-oriented electrical steel (NGOES) has emerged as a promising option for various applications. NGOES material plays a crucial role across the entire energy value chain, spanning from power generation through generators to the consumption of electrical energy in electric motors and appliances within the electrical components industry which can lead to a notable enhancement in the performance of electric motors. NGOES are widely used for soft magnetic applications due to their cost and also their superior magnetic properties, including high electrical resistivity, excellent saturation magnetization, and minimal magnetostriction. NGOES are anticipated to serve as a driving force in the future global market for electric power consumption. The magnetic properties of NGOES are profoundly influenced by metallurgical factors such as Si content, grain size, crystallographic texture, sheet thickness, and surface roughness. These crucial variables play a crucial role in shaping the magnetic characteristics of NGOES materials which will be covered in this review paper. This paper provides an overview of different manufacturing routes for NGOES, as well as the advantages and disadvantages of these processes. Moreover, alternative manufacturing techniques and their capability to optimize the microstructure and to fabricate high Si NGOES sheets are discussed. Also, it addresses the challenges associated with mass-producing materials with high Si content using traditional methods. These advancements in this area present promising opportunities for enhancing the manufacturing processes of NGOES and ultimately enhancing the performance of future electrical machines and generators.
