Optimization of the tooth geometry for axial flux machine with Non-Grain Oriented and Grain Oriented electrical steel
Year: 2025
Type: conference-paper
Abstract: Axial flux permanent magnet machines (AFPMM) are characterized by a very good torque-to-weight ratio and high energy efficiency, which makes them extremely attractive for applications such as electric vehicles, drones or even wind turbines. They are often compared with the best radial flux motors in terms of energy consumption as they can operate at over 95% efficiency. Taking as a reference an already studied AFPMM, this paper aims to improve its global performances, by segmenting the magnetic circuit and by using high-performance materials. A mixed structure constituted of a yoke made with Non-Oriented Grain Electrical Steel and teeth using Grain Oriented Electrical Steel is proposed. The optimization concerns the tooth geometry, considering the strong GOES anisotropy.
