Grain-oriented electrical steels (GOESs), the key components of transformers, should exhibit low energy losses and noise. Hence, the iron loss and magnetostriction (MS), which are determined by the magnetic domain structures of GOESs, should be minimized. Especially, the spacing of the 180° magnetic domain walls and angles, which dominate the magnetic properties of GOESs, should be modulated. In a previous study, a method to quantify the wall spacing and angle of a 180° magnetic domain simultaneously in GOESs based on 2-D Fourier transform (2DFT) was proposed. However, this method is difficult to apply to a large number of grains. In addition, the spatial information before the analysis is eliminated from the post-analysis information. To overcome these limitations, an extension of the 2DFT method is proposed; this extended method can be used to analyze the width and angle of a 180° magnetic domain wall while maintaining the spatial information. The results obtained using the proposed method agree well with the experimental results, demonstrating the effectiveness of the proposed method.

In order to improve the compression resistance and torque density of rim-driven thruster (RDT) to cope with complex and harsh deep-sea conditi ons, a flux-modulated RDT (FM-RDT) is proposed. This RDT uses a flux-modulated machine (FMM) as the driving machine, which utilizes a modulation ring to realize pressure protection in the deep sea and realizes the high-torque drive through the magnetic field modulation effect. The subdomain model is established in the air-gap and permanent magnet regions, and the permeance network (PN) model is established in the ferromagnetic regions. The nonlinear hybrid analytical model (HAM) of global magnetic field of FM-RDT is developed by combining the two models with boundary magnetic flux. The calculation results of HAM are compared with the finite element method (FEM), and the torque and magnetic saturation performance of the structure are analyzed. In addition, the open water hydrodynamic performance of FM-RDT is simulated and analyzed by using the computational fluid dynamics (CFD) method. The results show that the FM-RDT has a wider operating range and speed regulation range, and it is more suitable as the thruster for low-speed and heavy-duty deep-sea underwater vehicles.
