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。

钢珠轴承内外圈不平衡,是造成发热的原因之一。端子机内外圈的不平衡,可能来源于机加工。因为全自动端子机的机座和端盖是分开加工的,有时会有两个端盖上的轴承孔不共轴(即中心线不在一条线上)。另外,装配不良、端盖上螺钉松紧不均、止口上有灰尘及污物等,也可能使内外圈不平衡。如果轴承内外圈不平衡,会造成钢珠和内外圈相刮削,使摩擦增大而发热。如查无其他原因,将机口擦净重装,螺钉按对角顺序逐一旋紧。加工时所形成的少量误差,即可因逐渐的自动调整作用而改善。

用硅-蓝宝石半导体敏感元件制造的压力传感器和变送器,可在最恶劣的工作条件下正常工作,并且可靠性高、精度好、温度误差极小、性价比高。表压压力传感器和变送器由双膜片构成:钛合金测量膜片和钛合金接收膜片。印刷有异质外延性应变灵敏电桥电路的蓝宝石薄片,被焊接在钛合金测量膜片上。被测压力传送到接收膜片上(接收膜片与测量膜片之间用拉杆坚固的连接在一起)。在压力的作用下,钛合金接收膜片产生形变,该形变被硅-蓝宝石敏感元件感知后,其电桥输出会发生变化,变化的幅度与被测压力成正比。
