基于同心式永磁齿轮的运行机理,设计了一种新型的低速大转矩永磁复合电机模型,给出了模型参数化设计的计算方法。通过控制变量法,逐一改变调磁极块的长度、厚度,定子冲片轭铁厚度以及内转子轭铁的厚度等参数,再通过Ansoft有限元仿真软件对这些参数进行优化仿真。结果表明,可以有效提高电机的转矩密度,降低转速波动。

[Abstract]
Based on the mechanism of concentric permanent magnet gear, a new model of low speed and high torque permanent magnet compound motor was designed, and the calculation method of the basic parameters of the model was given. By controlling the variable method, the parameters such as the length of the pole block, the thickness of the stator punch and the thickness of the inner rotor yoke were changed, and the parameters were optimized by Ansoft finite element simulation software. The results showed that the motor torque density and reduce speed fluctuations were effectively improved.
