摘要
Slot inductance is the main component of inductance of yokeless and segmented armature (YASA) axial flux permanent magnet machine, which reduces the machine’s power factor and maximum output torque. This paper presents a calculation method for YASA machine’s slot inductance. The slot area is divided into multiple regular micro-elements, and a 2-D magnetic network model is used to calculate the magnetic energy stored in these micro-elements, considering core saturation. The slot inductance can be obtained by the calculated magnetic energy. Based on the proposed method, the influence of stator structure parameters and slot-pole combination on slot inductance is further studied and summarized. The simulation and experimental results show that the calculation method proposed for YASA machine’s slot inductance is feasible and accurate. ©2024 Chin.Soc.for Elec.Eng.
