摘要
介绍了直流电动机无传感器测速的实验方法,并选取了三台不同结构的直流电动机进行实验。实验结果中,有两例与现有的测速公式相同,一例与现有的测速公式稍有出入。若在公式中去除磁极对数这一因子,三例均能与此吻合。实验结果提示,传统的无传感器测速公式有修正必要。
The experiment method on sensorless speed estimation in DC motor and three special cases of DC motor with different number of poles and different number of commutator bars were presented. The results showed that there were two cases in accordance with the existing formula,but one case was not consistent with it. If the factor of number of pole - pairs was removed from the formula, all the three cases could be accordance with it. The results implyed that there were conflict in deep levels need be revealed.
