，了解常用的电路元器件，首先要学习常用电路元器件的电路符号，之后了解每一种常用电路元器件的功能作用，电路图都是由不同的电气元器件构成的，学习电工技术，想要看懂电路图，这是必经的过程。3，多看图纸，多练习，电工技术是理论知识和实践经验同等重要的技术，不仅需要理论知识，更需要实践经验，多看电路图纸，从基础的电路开始，:电机的正反转电路，星三角降压启动电路，顺序控制电路，两地控制电路等等。4，多动手实践，有条件的话对着电路图进行实物接线，把常用的电路图纸进行实物接线，自己动手往往比看别人操作进步要快，电工技术的学习一定要避免手高眼低。

《步进电机步距角度精度的测量》一文中提到的是两相HB型步进电机的例子，如每4步进位置定位，精度大幅提高。，每1.8°位置定位时，1.8°并非使用全步进，而是使用0.9°的步进电机，以2步进驱动1.8°位置定位，全步进选择0.6°的步进电机，3步进驱动有0.6°×3=1.8°的驱动方式。此种方式可以大大提高精度。电机的改善微调定子结构的改善：已知定子的微调结构能改善位置定位精度。以两相电机为例，微调结构，可以降低齿槽转矩，距角特性变为正弦波。

　　主要用于用于各种传感器，仪器仪表的信号传输。传感器信号电缆采用镀银导体，多芯结构，确保每芯之间电阻保持高度一致，可以将微弱的电量信号准确传输到数百米外。电话订货，厂家直接发货到目的地。由于铁路信号电缆市场的扩大，传统的铁路信号电缆市场规模预计会保持每年3000万芯公里左右的用量。
