　　理论上RS485通信电缆的传输距离能达到1200米，但实际应用中传输距离要小于1200米，具体长度受周围的环境影响。RS485总线一般大支持32个节点，如果使用特制的485芯片，可以达到128个或者256个节点，大的可以支持到400个节点。

两相步进电机简单的构成为Nr=1的情况，电机结构如下图所示。一般两相电机定子磁极数为4的倍数，至少是4。转子为N极与S极各一个的两极转子。定子一般用硅钢片叠压制作，定子磁极数为4极，相当于一相绕组占两个极，A相两个极在空间相差180°，B相两个极在空间也相差180°。电流在一相绕组内正负流动（此种驱动方式称为双极性驱动），A相与B相电流的相位相差90°，两相绕组中矩形波电流交替流过。即两相电机的定子，在Nr=1时，空间相差90°,时间上电流相差90°相位差，电流与普通的同步电机相似，在定子上产生旋转磁场，转子被旋转磁场吸引，随旋转磁场同步旋转。
