| 摘 要： | 根据4极直流电动机的转速与脉动电流频率关系的实验结果,对现有的无传感器直流电动机测速公式提出了修正意见。新的修正公式不仅能够解释文中的实验结果,也能满足以往文献提出的直流电动机转速与脉动电流频率之间的关系。

| Abstract: | Modified formula for sensorless DC motor speed estimation was proposed through the test for relationship between the current ripple frequency and the rotation speed in a 4-pole DC motor.The new modified formula not only meets with our experiment result,but also can explain the examples of relationship between the speed and the current ripple frequency of DC motors in the literature. |
