无人机驱动详解

电(dian)调(diao)是(shi)(shi)电(dian)子调(diao)速(su)器(qi)的(de)简(jian)(jian)称(cheng)，英文Electronic Speed Control，简(jian)(jian)称(cheng)ESC，针对电(dian)机不同，可分(fen)为有刷电(dian)调(diao)和无(wu)刷电(dian)调(diao)，他根据(ju)控制信号调(diao)节电(dian)动机的(de)转速(su)，但是(shi)(shi)现在的(de)无(wu)刷电(dian)调(diao)所拥(yong)有的(de)功能远不止这(zhei)一个调(diao)速(su)的(de)功能。

我(wo)(wo)们(men)从(cong)最早(zao)的(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)调(diao)(diao)(diao)谈起吧(ba)，最早(zao)的(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)调(diao)(diao)(diao)可不(bu)是(shi)(shi)(shi)像现在的(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)调(diao)(diao)(diao)一(yi)样(yang)，最早(zao)全是(shi)(shi)(shi)有刷(shua)(shua)(shua)(shua)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)调(diao)(diao)(diao)，说(shuo)(shuo)道(dao)这你(ni)可能要问(wen)了，什么是(shi)(shi)(shi)有刷(shua)(shua)(shua)(shua)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)调(diao)(diao)(diao)，和现在的(de)(de)无(wu)刷(shua)(shua)(shua)(shua)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)调(diao)(diao)(diao)有什么区别。事实上这差别呀可大(da)了去(qu)了，有刷(shua)(shua)(shua)(shua)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)调(diao)(diao)(diao)和无(wu)刷(shua)(shua)(shua)(shua)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)调(diao)(diao)(diao)都(dou)是(shi)(shi)(shi)根(gen)(gen)据(ju)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)来说(shuo)(shuo)的(de)(de)，现在电(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)的(de)(de)转子，就(jiu)是(shi)(shi)(shi)能转动的(de)(de)部分(fen)全是(shi)(shi)(shi)磁(ci)铁块(kuai)，线圈是(shi)(shi)(shi)定子不(bu)转动的(de)(de)，因为这中间(jian)没(mei)有碳刷(shua)(shua)(shua)(shua)，这就(jiu)是(shi)(shi)(shi)无(wu)刷(shua)(shua)(shua)(shua)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)。而(er)有刷(shua)(shua)(shua)(shua)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)呢，顾名(ming)思(si)义就(jiu)是(shi)(shi)(shi)有碳刷(shua)(shua)(shua)(shua)，所以就(jiu)是(shi)(shi)(shi)有刷(shua)(shua)(shua)(shua)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)，像我(wo)(wo)们(men)平常(chang)小孩(hai)子玩的(de)(de)一(yi)二十块(kuai)钱的(de)(de)遥控车用(yong)的(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)就(jiu)是(shi)(shi)(shi)有刷(shua)(shua)(shua)(shua)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)。电(dian)(dian)(dian)(dian)(dian)(dian)(dian)调(diao)(diao)(diao)就(jiu)是(shi)(shi)(shi)根(gen)(gen)据(ju)这两种电(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)而(er)命名(ming)的(de)(de)有刷(shua)(shua)(shua)(shua)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)调(diao)(diao)(diao)和无(wu)刷(shua)(shua)(shua)(shua)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)调(diao)(diao)(diao)。从(cong)专业的(de)(de)角(jiao)度来讲呢就(jiu)是(shi)(shi)(shi)有刷(shua)(shua)(shua)(shua)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)调(diao)(diao)(diao)就(jiu)是(shi)(shi)(shi)输出时(shi)直(zhi)(zhi)流(liu)(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)，无(wu)刷(shua)(shua)(shua)(shua)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)调(diao)(diao)(diao)输出是(shi)(shi)(shi)三(san)(san)相(xiang)交(jiao)(jiao)流(liu)(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)。直(zhi)(zhi)流(liu)(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)就(jiu)是(shi)(shi)(shi)我(wo)(wo)们(men)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)池里存储的(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)，有正(zheng)负(fu)极之分(fen)，我(wo)(wo)们(men)家用(yong)220V的(de)(de)，用(yong)于手机(ji)充电(dian)(dian)(dian)(dian)(dian)(dian)(dian)器或者(zhe)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)脑的(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)源都(dou)是(shi)(shi)(shi)交(jiao)(jiao)流(liu)(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)。交(jiao)(jiao)流(liu)(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)就(jiu)是(shi)(shi)(shi)带有一(yi)定的(de)(de)频(pin)率(lv)，通俗讲就(jiu)是(shi)(shi)(shi)一(yi)根(gen)(gen)线上正(zheng)负(fu)、正(zheng)负(fu)的(de)(de)来回(hui)交(jiao)(jiao)换着；直(zhi)(zhi)流(liu)(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)就(jiu)是(shi)(shi)(shi)正(zheng)极是(shi)(shi)(shi)正(zheng)极，负(fu)极是(shi)(shi)(shi)负(fu)极。交(jiao)(jiao)流(liu)(liu)(liu)直(zhi)(zhi)流(liu)(liu)(liu)弄清楚了，那(nei)么什么又是(shi)(shi)(shi)“三(san)(san)相(xiang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)”呢？理(li)论讲三(san)(san)相(xiang)交(jiao)(jiao)流(liu)(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)是(shi)(shi)(shi)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)一(yi)种传输形式，简称三(san)(san)相(xiang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)，是(shi)(shi)(shi)由3个频(pin)率(lv)相(xiang)同(tong)、振(zhen)幅(fu)相(xiang)等(deng)、相(xiang)位依次(ci)互差120度的(de)(de)交(jiao)(jiao)流(liu)(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)势组成的(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)源。通俗的(de)(de)讲，就(jiu)是(shi)(shi)(shi)我(wo)(wo)们(men)家用(yong)的(de)(de)三(san)(san)项(xiang)交(jiao)(jiao)流(liu)(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)，除了电(dian)(dian)(dian)(dian)(dian)(dian)(dian)压(ya)、频(pin)率(lv)、驱(qu)动角(jiao)不(bu)同(tong)，其他都(dou)一(yi)样(yang)，现在对于三(san)(san)相(xiang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)和直(zhi)(zhi)流(liu)(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)都(dou)了解了吧(ba)。

无刷直流电机介绍

无刷(shua)电(dian)(dian)(dian)调(diao)(diao)原理与有(you)刷(shua)电(dian)(dian)(dian)调(diao)(diao)类似也(ye)是(shi)(shi)(shi)(shi)通过单片机控(kong)制MOS管调(diao)(diao)节的(de)(de)输出电(dian)(dian)(dian)压而(er)实现(xian)的(de)(de)电(dian)(dian)(dian)机调(diao)(diao)速的(de)(de)，但与有(you)刷(shua)电(dian)(dian)(dian)调(diao)(diao)最大的(de)(de)区别就(jiu)是(shi)(shi)(shi)(shi)它内(nei)置(zhi)我(wo)们常说的(de)(de)逆变器功(gong)能(neng)，输出的(de)(de)是(shi)(shi)(shi)(shi)三(san)相交流电(dian)(dian)(dian)，频(pin)率是(shi)(shi)(shi)(shi)8000HZ，我(wo)们正(zheng)常的(de)(de)家(jia)用电(dian)(dian)(dian)频(pin)率是(shi)(shi)(shi)(shi)50HZ，相比(bi)家(jia)用电(dian)(dian)(dian)是(shi)(shi)(shi)(shi)不是(shi)(shi)(shi)(shi)高(gao)多(duo)了。正(zheng)是(shi)(shi)(shi)(shi)因为他频(pin)率高(gao)，所(suo)以无刷(shua)电(dian)(dian)(dian)机功(gong)率才大了，线圈缠绕只(zhi)有(you)几匝（圈数）而(er)不会短路。但是(shi)(shi)(shi)(shi)这么小的(de)(de)一个(ge)电(dian)(dian)(dian)调(diao)(diao)它的(de)(de)逆变器又是(shi)(shi)(shi)(shi)什(shen)么样的(de)(de)呢？让我(wo)来给你解答。

无(wu)刷电(dian)(dian)调(diao)(diao)(diao)(diao)，输(shu)(shu)入(ru)的(de)是(shi)直流电(dian)(dian)，通(tong)过一(yi)个(ge)(ge)滤(lv)波电(dian)(dian)容稳定(ding)电(dian)(dian)压。然(ran)后分成俩两路，一(yi)路是(shi)电(dian)(dian)调(diao)(diao)(diao)(diao)的(de)BEC使(shi)(shi)用(yong)(yong)，BEC是(shi)给(ji)接收机(ji)与电(dian)(dian)调(diao)(diao)(diao)(diao)自身单片机(ji)供电(dian)(dian)使(shi)(shi)用(yong)(yong)的(de)，输(shu)(shu)出(chu)至接收机(ji)的(de)电(dian)(dian)源线(xian)就是(shi)信(xin)号(hao)(hao)线(xian)上(shang)的(de)红线(xian)和(he)(he)黑(hei)线(xian)，另一(yi)路是(shi)介(jie)入(ru)MOS管(guan)使(shi)(shi)用(yong)(yong)，在(zai)这(zhei)(zhei)里，电(dian)(dian)调(diao)(diao)(diao)(diao)上(shang)电(dian)(dian)，单片机(ji)开始启动(dong)(dong)，驱(qu)动(dong)(dong)MOS管(guan)震动(dong)(dong)，使(shi)(shi)电(dian)(dian)机(ji)发出(chu)滴(di)(di)滴(di)(di)滴(di)(di)的(de)声音。启动(dong)(dong)后待(dai)命，有些(xie)电(dian)(dian)调(diao)(diao)(diao)(diao)带有油门校准(zhun)功能(neng)，在(zai)进(jin)入(ru)待(dai)命前(qian)会(hui)监(jian)测油门位置是(shi)在(zai)高(gao)还是(shi)低还是(shi)中间，高(gao)的(de)话进(jin)入(ru)电(dian)(dian)调(diao)(diao)(diao)(diao)行程校准(zhun)，中间的(de)话开始发出(chu)报警信(xin)号(hao)(hao)，电(dian)(dian)机(ji)会(hui)滴(di)(di)滴(di)(di)的(de)响，低的(de)话会(hui)进(jin)入(ru)正(zheng)常工(gong)作(zuo)状态。一(yi)切准(zhun)备就绪(xu)后，电(dian)(dian)调(diao)(diao)(diao)(diao)内(nei)的(de)单片机(ji)会(hui)根(gen)据PWM信(xin)号(hao)(hao)线(xian)上(shang)的(de)信(xin)号(hao)(hao)决(jue)定(ding)输(shu)(shu)出(chu)电(dian)(dian)压的(de)大小和(he)(he)频(pin)率的(de)高(gao)低以(yi)及(ji)驱(qu)动(dong)(dong)方(fang)向和(he)(he)进(jin)角(jiao)多(duo)少(shao)来(lai)驱(qu)动(dong)(dong)电(dian)(dian)机(ji)的(de)转速，转向。这(zhei)(zhei)就是(shi)无(wu)刷电(dian)(dian)调(diao)(diao)(diao)(diao)原理。在(zai)驱(qu)动(dong)(dong)电(dian)(dian)机(ji)运转的(de)时候，电(dian)(dian)调(diao)(diao)(diao)(diao)内(nei)共有3组MOS管(guan)工(gong)作(zuo)，每组2个(ge)(ge)极，一(yi)个(ge)(ge)控制正(zheng)极输(shu)(shu)出(chu)，一(yi)个(ge)(ge)控制负极输(shu)(shu)出(chu)，当(dang)正(zheng)极输(shu)(shu)出(chu)时，负极不输(shu)(shu)出(chu)，负极输(shu)(shu)出(chu)时，正(zheng)极不输(shu)(shu)出(chu)，这(zhei)(zhei)样子也就形成了交流电(dian)(dian)，同样，三组都是(shi)这(zhei)(zhei)样工(gong)作(zuo)的(de)，它们的(de)频(pin)率是(shi)8000HZ。讲到这(zhei)(zhei)，无(wu)刷电(dian)(dian)调(diao)(diao)(diao)(diao)也相(xiang)当(dang)于一(yi)个(ge)(ge)工(gong)厂里电(dian)(dian)机(ji)上(shang)使(shi)(shi)用(yong)(yong)的(de)变频(pin)器或(huo)者调(diao)(diao)(diao)(diao)速器。

除了这些基本(ben)的(de)(de)功(gong)能(neng)呢，电(dian)(dian)(dian)(dian)(dian)调(diao)还(hai)有电(dian)(dian)(dian)(dian)(dian)池(chi)低压保护功(gong)能(neng)以(yi)(yi)(yi)及(ji)监测电(dian)(dian)(dian)(dian)(dian)池(chi)电(dian)(dian)(dian)(dian)(dian)压功(gong)能(neng)，最早的(de)(de)无刷电(dian)(dian)(dian)(dian)(dian)调(diao)都支持(chi)双电(dian)(dian)(dian)(dian)(dian)池(chi)模(mo)式，也就(jiu)(jiu)是现(xian)在(zai)的(de)(de)锂聚合物电(dian)(dian)(dian)(dian)(dian)池(chi)和以(yi)(yi)(yi)前的(de)(de)镍(nie)氢(qing)电(dian)(dian)(dian)(dian)(dian)池(chi)。通过遥控油门杆根据电(dian)(dian)(dian)(dian)(dian)机(ji)的(de)(de)提示音可以(yi)(yi)(yi)修改供电(dian)(dian)(dian)(dian)(dian)模(mo)式以(yi)(yi)(yi)及(ji)电(dian)(dian)(dian)(dian)(dian)调(diao)的(de)(de)进(jin)角(jiao)(jiao)(jiao)和刹车(che)(che)灯功(gong)能(neng)，刚刚讲(jiang)到进(jin)角(jiao)(jiao)(jiao)和刹车(che)(che)功(gong)能(neng)，那么(me)什么(me)又是进(jin)角(jiao)(jiao)(jiao)和刹车(che)(che)功(gong)能(neng)呢，听我来给你(ni)慢慢讲(jiang)，上面我们讲(jiang)到家用三相交流电(dian)(dian)(dian)(dian)(dian)相位角(jiao)(jiao)(jiao)120度，这就(jiu)(jiu)是家用电(dian)(dian)(dian)(dian)(dian)的(de)(de)进(jin)角(jiao)(jiao)(jiao)，现(xian)在(zai)的(de)(de)电(dian)(dian)(dian)(dian)(dian)调(diao)提供高(gao)中低三个(ge)进(jin)角(jiao)(jiao)(jiao)，如果(guo)负载比较(jiao)(jiao)重就(jiu)(jiu)用高(gao)进(jin)角(jiao)(jiao)(jiao)，如果(guo)负载轻(qing)就(jiu)(jiu)用中或(huo)低进(jin)角(jiao)(jiao)(jiao)，进(jin)角(jiao)(jiao)(jiao)为0或(huo)者负数(shu)的(de)(de)时候，马(ma)达较(jiao)(jiao)为省电(dian)(dian)(dian)(dian)(dian)，但是无力(li)，有进(jin)角(jiao)(jiao)(jiao)的(de)(de)马(ma)达较(jiao)(jiao)为有力(li)，但耗电(dian)(dian)(dian)(dian)(dian)。
