基于交流变频电机的不平衡量检测算法分析

摘要

分析了洗衣机滚筒进行衣物不平衡量检测的原因,从理论上分析了不采用机械装置的不平衡检测原理,最后提出了根据电机控制器输出电压估算不平衡量的检测方法.为了验证根据电机控制器输出电压估算不平衡量的有效性,对洗衣机进行了不平衡量检测实验,实验结果表明该检测方法的有效性.%The reason that drum washing machines need to measure unbalance of clothes was analyzed. After analyzing the unbalance measuring principle without the mechanical device, a unbalance measuring method according to output voltage of variable frequency motor was proposed. The results of the experiment on a drum washing machine show that the method is valid.
