脉冲分配可由硬件或软件来实现。作为硬件，目前市场上已有专用的分配器功能组件出售。采用专用集成电路有利于提高系统可拿性和降低系统成本。用微机控制步进电机，采用汇编语言编制程序来分配脉冲，称为软件脉冲分配。这种方法的特点是控制灵活、可靠性高、制造成本低。当然，它需编制复杂的程序，需占用大量内存单元和操作时间。

由于步进电机的角位移量和指令脉冲的个数成正比，旋转方向与通电相序有关，因此只要控制输入脉冲的数量、频率和电机绕组的通电相序，即可获得所需的转角大小、转速和方向。其调速范围广、响应侠、灵敏度离、控制系统简单，而且有一定的精度，所以被广泛应用于开环步进系统中。

锁虽然是五金小配件，包含在门窗五金配件里面，在日常生活中却起到至关重要的作用，因此要注意如何保养好。下面为大家总结了一些关于锁具的保养方法：门锁不好开关时，喷些润滑油于斜舌上。有些锁心是不能加油的，(极少)如子母珠锁心。门缝不能太大，容易被拨开及晃动声响。钥匙不好插入或抽出时，喷些清淡的润滑油，(如w4)不能太浓的油会不活动。防盗门有花格子型，防被用铁丝伸入勾开自动锁的斜锁拉把，把门拉开。
