摘要:
为了提高轴向磁场无铁心永磁无刷直流电动机设计的准确性,提出了利用电磁场有限元软件与磁路法相结合的方法设计该电机.结合轴向磁场无铁心永磁无刷直流电机的电磁结构特点,首先利用磁路法推导了该电机的尺寸设计方程,分析了电机设计中的各种损耗,并根据流程图编制了设计程序,对额定功率为40 W的小型电机提出了设计方案.利用三维有限元分析软件对设计方案中的关键参数(永磁体厚度、极对数与极弧系数)进行了仿真与分析.结果表明:当永磁体厚度为6 mm,永磁体极对数为4时,电机气隙磁密相对最大且磁密增长率较快;当极弧系数为0.7时,感应电动势基波幅值最大.最后设计了样机,利用三维有限元分析方法验证了样机设计的有效性.
Abstract:
In order to improve the design exactness, the design of an axial-flux coreless permanent magnet brushless dc motor based on both finite-element analysis(FEA)and the magnetic circuit method is presented. Considering the characteristics of the axial-flux coreless permanent magnet brushless dc motor, the basic dimension design equations are derived based on the magnetic circuit method. The losses of the motor are analyzed. Based on the design flowchart, a computer-aided design(CAD)procedure for the motor is presented. The motor of rating 40 W is designed using the developed program. Three-dimensional FEA is carried out to optimize the key design parameters, including the height, the pole number and the pole arc coefficient of permanent magnets(PMs). The results indicate that when the height of PMs is 6 mm and the pole number is 4, the air gap flux density is relatively large and has a rapid growth. When the pole arc coefficient of PMs is 0.7, the induced fundamental voltage is the highest. Finally, a sample motor is designed and FEA is used to validate the effectiveness of the proposed design.
