Ansoft Maxwell-based Finite Element Analysis of a Permanent Magnet DC Hollow Cup Motor

永磁直流空心杯电机是空心杯电机的一种,体积小重量轻、转动惯量小、工作效率高、功率密度高,在航空航天及国防军事装备领域得到广泛的应用。以永磁直流空心杯电机为模型,运用Ansoft Maxwell软件搭建仿真模型,进行网格剖分、材料赋予及激励源等设置。求解并分析模型在稳态的磁场分布及瞬态的输出特性,为电机的设计与优化提供参考依据。

Permanent magnet DC hollow cup motor is a kind of hollow cup motor,small size and light weight,low rotational inertia,high efficiency and high power density,which is widely used in the field of aerospace and defence military equipment.Using a permanent magnet DC hollow cup motor as a model,the simulation model was built using Ansoft Maxwell software,and settings such as mesh dissection,material assignment and excitation source were made to solve.Analyse the steady-state magnetic field distribution and transient output characteristics of the model,providing a reference basis for motor design and optimisation.
