第106章 交流电机控制系统

苏良宇听梁远说完沉默了许久，心中对梁远的佩服却更深了一分，这话换成任何一个人说，苏良宇都会当作冠冕堂皇的说词，换成梁远苏良宇却深信不疑，12月梁远从唐婉口中得知明年国家出台“私营企业暂行条例”已成定局之后，直接把苏良宇的年薪悄无声息的提至20万元，并签了一份包括最多6%股权激励的五年期合约。
在美国生活多年的苏良宇，对这份合同背后的含义十分了解，梁远是真心把自己当作事业的合伙人对待。梁远某些恰到好处的行为，常常使苏良宇有种同国外开明投资人合作的错觉。真不知道没在国外生活过，没受过国外教育的梁远是从哪里了解到西方社会、企业运行知识的，像给自己的那份合约，没在西方社会生活过，接触过最前沿的计算机行业，是绝开不出那种合同的。
“听小远一说，好像不回国工作，我这位同学将会在悔恨中度过余生似的。”苏良宇决定把困扰扔在脑后，某些人在某些事上大约真是天授吧。
“呵呵，老苏，这可是你说的，我是绝对不会承认的，老苏你可以问问你同学，农历年过后若有时间可以来盛京转转，不管有没有一起工作的缘分，回国看看也是件不错的事嘛，国家这几年的变化还是很大的。”
“过年时我问问。”
两人边说边走进了走进了芯片实验室。
交流电机的控制控制系统相对于直流电机要复杂的多，直流电机调速只是简单的改变电压就可以了，而交流电机调速需要频繁的进行整流逆变，在整流的时候改变了电压，在逆变的时候改变了频率，从而达到电机调速的目的。
梁远眼前放着一台巴掌大的圆形驱动电机，电机外裸接着几根导线，导线从一块镶嵌着三块大型芯片的电路板中穿出，电路板上还有数根导线，连接着几个开关旋钮样的器件，苏良宇亲自动手接通了电机电源，一声轻微的嗡声过后，电机安静的转动了起来，苏良宇示意梁远扭动电路板上的开关和旋钮。
梁远把所有的按键一一试过一遍才发现，苏良宇研发的这套交流电机调速系统已经无限接近于成品状态，三个微处理器一个用来处理监视电机转数的霍尔元件发回来的数据，一个用来处理电机的无级变速，还一个用来处理预先设定好的高、中、低三档固定风速。
“老苏，这东西外边套个盒子是不是就是一款简单的plc（注2）成品了。”梁远好奇问道。
“离真正的plc差远了，真正的plc可以控制各种工业设备，兼容性极高，用途非常广泛，我们研发这套东西只能控制和这款小型电机性能差不多的电机，别的活可干不了，只能说这套系统是针对小型交流电机控制的简单plc系统。”
“暂时能有这个我就满足了，老苏，我还是很好打发的嘛。”梁远有些感慨的说道。
现在苏良宇这套东西拿出去混个国家金奖是绝对不成问题的，梁远虽然不知道前世的国内交流电机调速系统研发始于何年，但梁远敢肯定产生一定影响绝对不会早于九十年代中期，这方面的工作还是台湾电子产业大规模转移至大陆，有了足够规格品种的单片机供应，有了相对完善的各种ti工程师认证后，才逐渐步入正轨的。
早年的国内的交流电机调速研究除了纯理论研究，就是在买回来国外成品plc上进行编程工作，只能说是知其然不知其所以然罢了。
“老苏，这套系统最多能用到多大功率的电机上？”梁远问道。
“不超过50瓦，通过简单修改参数都能匹配上，不过精度就不要指望了。”
“能用就好，除了无叶风扇，我这里还有份赚钱的买卖可指望着老苏这个东西呢”梁远笑着说道。
注1：当时叫梅兰日兰。
注2：全名为可编程逻辑控制器，实质是一种专用于工业控制的计算机。
