定子为爪极型的步进电机,气隙为0.2mm(比HB型步进电机的气隙大3~4倍)。其分辨率与相同尺寸的HB型步进电机相比相差1/4。与相同尺寸的HB型步进电机相比,其转矩只有1/3。决定步距角的分辨率由式θs=180°/PNr得知,如P=2,则θs=90°/Nr。若Nr=5~12,则步距角θs为1.8°~7.5°,通常使用7.5°。下图示为PM型步进电机的外观及PM型步进电机(42×长度27mm,步距角7.5°)的速度-转矩特性[与尺寸接近的HB型步进电机(39×长度27mm,步距角1.8°)比较]。

对于电工来说,接触器是Zui常见的电器元件了,特别是Zui常用的交流接触器,可以说无处不在。如何巧妙而又熟练的使用接触器的常开常闭点,是我们每个新手都要思考的问题,摸熟它,吃透它,对我们以后看懂电路图,分析电路图和应用电路图都很重要。如果把学电路比喻成学开车的话,那么自锁和互锁就好像是学开车的挂档和换挡,基础的基础,重中只重。好的,废话少说。我们先来看接触器的外形和构成,如图如所示,接触器共有六个主触点,1,3,5为输入端(入线孔),2,4,6为输出端(出线孔),这个接触器的主触点的额定电流为12安,A1,A2为接触器线圈的两个接线点,在接触器的主触点的稍下方。

  本安信号控制电缆具有低电容和低电感,并具有极好的屏蔽性能和抗干扰性能,因而防爆性能优于一般计算机缆和控缆。1、电缆型号、名称及使用范围型号名称使用范围ia-K2YV本安型PE绝级、PVC护套二芯绞合屏蔽控制电缆固定敷设在室内、电缆沟或管道中。

  接地引出线要求采用我镀锡编织铜线,和电缆铜带连接时应用铬铁锡焊,不宜用喷灯封焊,以免烧损绝缘。③三相铜带屏蔽应分别与地线相连,注意屏蔽接地线和钢铠接地线应分别引出,相互绝缘,焊接地线的位置应尽量靠下。对电缆端头和中间接头的基本要求:a.导体连接好;b.绝缘可靠,推荐采用辐照交联热收缩型硅橡胶绝缘材料;c.密封良好;d.足够的机械强度,能适应各种运行条件。
