　1.何为步进电机的驱动。

　　步进电机是一种作为控制用的特种电机, 它的旋转是以固定的角度(称为“步距角”)一步一步运行的, 其特点是没有积累误差(精度为), 所以广泛应用于各种开环控制。

　　步进电机的运行要有一电子装置进行驱动, 这种装置就是步进电机驱动器, 它是把步进电机控制系统发出的脉冲信号转化为步进电机的角位移, 或者说步进电机控制系统每发一个脉冲信号, 通过步进电机驱动器就使步进电机旋转一步距角。所以步进电机的转速与脉冲信号的频率成正比。

　　所以，控制步进电机脉冲信号的频率，可以对步进电机调速；

　　控制步进电机步进脉冲的个数，步进电机驱动器可以实现对步进电机目的；

为了保持部件的物理和化学性能，应遵守下述规则:热：理想的贮存温度是在+5C至+25C，应避免直接和热源接触，诸如锅炉、散热器，避免阳光直射。如果温度低于+5C，挖掘封件可能是僵硬的，在取放时应小心，使用前应使挖掘封件的温度回升到25C左右。氧气和臭氧：如果可能，弹性体应包装并存放在密封的容器内，不受空气的影响。由于臭氧可使弹性体受损，贮存弹性体的处所内不应放置可能产生臭氧的设备，紫外线灯、高压设备、电动机、电火花源或静态放电。
