【摘要】：合理控制齿槽转矩可以降低电机的振动和噪声。为了降低永磁同步电机的振动和噪声,对影响齿槽转矩的四个主要参量(极弧系数、偏心距、气隙长度、磁极厚度)进行优化,然后利用有限元分析软件,进行电机的振动和噪声的分析。首先利用正交试验选取一定数量的样本;然后利用支持向量机对其进行拟合,得到回归方程;利用微粒群优化算法对其回归方程进行寻优,得到理想的齿槽转矩;最后将齿槽转矩带入电机模型中进行电机的振动和噪声的分析。
[Abstract]:Can reduce the vibration and noise of motor control is reasonable. In order to reduce the cogging torque of permanent magnet synchronous motor vibration and noise, the influence of four main parameters of cogging torque (pole arc coefficient, eccentricity, air gap length, thickness of magnetic pole) was optimized, and then using the finite element analysis software, analyzed the vibration and noise of motor the first selects a certain number of the orthogonal test sample; and then use the support vector machine to fit it, get the regression equation; using particle swarm optimization algorithm to optimize the regression equation, tooth slot torque ideal; finally analyzes the vibration and noise of the motor model into the cogging torque.
