适配功率电机齿槽转矩削弱方法研究
|
摘要
为削弱适配功率电机齿槽转矩,提高该电机动力输出性能,提出了匹配相邻磁极极弧系数的方法。首先,运用麦克斯韦应力张量法和傅里叶分解求解适配功率电机齿槽转矩解析模型,并对不等极弧系数进行匹配组合,解析结果表明齿槽转矩削弱了35%左右。然后,采用全局优化算法对不等极弧系数进行全局寻优匹配,齿槽转矩进一步得到优化。最后,依据理论研究结果加工制作样机并进行试验,试验结果显示,齿槽转矩实测数据和优化结果相比,总体误差为5%左右,且整体趋势与优化曲线相符。因此,所提用于削弱适配功率电机齿槽转矩的方法是有效且可行的。
In order to reduce the cogging torque,improve the motor power output performance,put forward a method of matching pole arc coefficient of the adjacent pole. Used the Maxwell stress tensor method and Fourier decomposition solve the cogging torque analytical model of the power adaptive motor,and combined the different pole arc coefficients,analysis results showed that the reducing of cogging torque was about 35%. Then,unequal pole arc coefficients were globally optimized by the global optimization algorithm,showed that the cogging torque was further optimized. Finally,the prototype was produced on the basis of the results of theoretical research and given a prototype test,the results showed that: compared to the cogging torque measured data and the results of optimization,the overall error was about 5%,and the overall trend curve matches the optimization. Therefore,in this paper the method of weakening cogging torque of the power adaptive motor was effective and feasible.
