见图 1、 图 2所示， 一般电子换向驱动电机包括电机实体和电机 控制器， 电机实体包括电机的定子和转子部分， 电机控制器除了需要 与电机实体匹配外，还需要与电机具体的应用系统一即用户端控制系 统的控制接口匹配，因为不同的用户端控制系统匹配不同的控制信号， 例如空调控制系统与洗衣机控制系统都是用户端的控制系统，两个系 统的控制信号完全不一样。传统的做法是针对每一种用户端控制系统 就开发一种电机及电机控制器， 这样一来产生如下问题： 1 ) 电机厂 家生产的电机型号非常多， 不便于管理和标准化； 2 ) 浪费开发时间 和研发的投入，因为每一个新的用户端控制系统都需要重新开发一款 电机， 增加产品的制造成本； 3 ) 重新设计需要制定新的生产工艺和 认证成本， 增加了投入； 4 ) 电机应用范围非常窄， 不便于大范围推 广应用。
为了解决上述的技术问题，现在出现了一些子母线路板对接的电 机控制器， 将电机控制器的主要功能电路设置在母线路板上， 将多种 的接口单元电路和身份识别电路设置在多个子线路板上，利用其中一 个子线路板与母线路板对接，子线路板上的身份识别电路通知母线路 板上的微处理器单元，由微处理器单元自动配置子线路板上的 I /O口 类型， 从而可以通过更换不同的子线路板就可以应用不同场合， 应用 范围广， 电机生产厂家减少电机的种类便于管理， 可以减少电机的研 发投入、 缩短研发周期， 降低产品成本， 简化生产工艺， 提高效率。
