【摘要】：以横向叠片转子同步磁阻电机(TLR-Syn RM)为研究对象,提出了一种绝缘磁障渐变型转子结构。首先,在保证各层绝缘磁障直线段与圆弧曲线段宽度相等的条件下,分析绝缘磁障"渐变"的几何特征,推导出在较小转矩脉动下,各结构参数间所满足的解析表达式。其次,在解析法所设计的初始电机模型基础上,结合有限元法和二维等高线分析法获得结构参数与转矩脉动的函数关系,为采用Taguchi法的水准选取提供可靠依据。再次,利用Taguchi法建立正交表、设计正交试验,优化调整电机结构参数,寻求低转矩脉动的最优解。最后,根据所提出的方案设计并研制了实验样机,仿真和样机试验表明,该绝缘磁障渐变型转子结构可以有效地抑制电机的高转矩脉动,验证了优化设计方案的可行性。
[Abstract]:The transverse laminated rotor synchronous reluctance motor (TLR-Syn RM) as the research object, a graded insulation magnetic barrier rotor structure is proposed. Firstly, in which the insulating magnetic barrier line segments and circular segment width under the same geometric analysis of insulating magnetic barrier "gradient" characteristics, are derived in the the smaller torque ripple, the analytical expressions satisfy the structure parameter. Secondly, based on the initial model of the motor design analytical method, combining the function of finite element method and 2D contour analysis method to obtain the structure parameters and the torque ripple, which is using the Taguchi method of the standard selection to provide reliable basis. Thirdly, the establishment of orthogonal table Taguchi method using orthogonal design, optimization and adjustment of structural parameters of the motor, the optimum seeking low torque ripple solution. Finally, according to the proposed design scheme and developed the experimental prototype, simulation and experiment of the vast The edge magnetic barrier gradient rotor structure can effectively suppress the high torque ripple of the motor, and the feasibility of the optimal design scheme is verified.
