0 引言
伴随着城市化进程，人们生活的交通距离不断扩大，代替燃油汽车和自行车的电动车的普及大幅度的提高了电力资源的利用效率，促进了国民经济的健康发展。电动自行车以电力作动力，骑行中不产生污染，无损于空气质量。从改善人们的出行方式、保护环境和经济条件许可情况等因素综合来看，电动自行车目前乃至今后都有着广阔的发展空间。电动自行车所用直流电机分为有刷电机和无刷电机两种。其中有刷电机控制较简单。但其易磨损的电刷带来维修保养工作量相对较大、使用寿命相对较短等缺点。而直流无刷电机本身没有易磨损部件，电机寿命长，维修保养工作量小。但直流无刷电机采用电子换向原理工作，其控制过程比有刷电机复杂得多，因此对控制器质量的要求也高得多。57404-3 /57C404C
目前电动自行车采用的直流无刷电机都是三相电机，电角度有60°和120°两种。电机极数大部分为18极，也有16极、20极等。控制器根据霍尔反馈的电机电极位置，控制相应的功率驱动管的开通或关断，在定子中产生旋转磁场，驱动电机的转子转动。
为了判断无刷控制器是否能够正常运行，也就是检测转把和刹车功能是否正常，判断控制器的角度是60°还是120°，并且确定绕组A，B，C相与位置信号a，b，c之间的对应关系，正确地将控制器与电机进行连接，现在很多的检测仪器都采用模拟电路，使得结果不是很精确，而且需要的电路也很复杂，成本很大。设计采用STCl2C5410AD单片机作为控制芯片，大大简化了硬件电路，以软件编程来实现。

l 电动车无刷电机控制器简介
控制器由周边器件和主芯片(或单片机)组成。周边器件是一些功能器件，如执行、采样等，它们是电阻、传感器、桥式开关电路，以及辅助单片机或集成电路完成控制过程的器件；单片机也称微控制器，是在一块集成片上把存贮器、有变换信号语言的译码器、锯齿波发生器和脉宽调制功能电路以及能使开关电路功率管导通或截止、通过方波控制功率管的的导通时间以控制电机转速的驱动电路、输入输出端口等集成在一起，而构成的计算机片。这就是电动自行车的智能控制器。
控制器的设计品质、特性、所采用的微处理器的功能、功率开关器件电路及周边器件布局等，直接关系到整车的性能和运行状态，也影响控制器本身性能和效率。不同品质的控制器，用在同一辆车上，配用同一组相同充放电状态的电池，有时也会在续驶能力上显示出较大差别。
目前，电动自行车所采用的控制器电路原理基本相同或接近。有刷和无刷直流电机大都采用脉宽调制的PWM控制方法调速，只是选用驱动电路、集成电路、开关电路功率晶体管和某些相关功能上的差别。元器件和电路上的差异，构成了控制器性能上的不同。

2 系统硬件电路设计
为了判断无刷控制器是否正常，测量控制器各个部分的输出信号是否符合标准，并且能够接收电机、转把、刹车的信号，判断这个控制器是否能实现其需要实现的功能，系统要检测控制器的转把和刹把是否有稳定的5 V电压输出，判断控制器的角度，以及判断霍尔控制线相序及与其对应的电机电源相序是否*。只有位置传感器信号和绕组A，B，C正确连接才能使电机正常运行。图1为电路整体设计原理图，系统采用STCl2C5410AD单片机作为主要控制芯片。STCl2C5410AD系列单片机是宏晶科技生产的单时钟／机器周期(1T)的单片机，是高速、低功耗、*抗干扰的新一代8051单片机，指令代码*兼容传统8051，但速度快8～12倍，内部集成MAX810复位电路，4路PWM，8路高速10位A／D转换，专门针对强干扰场合电机控制。
