March-May步進電機驅動器和控制(zhi)器有(you)什么區別

東莞(guan)天驥自動(dong)化設備(bei)(bei)有限公(gong)司是一(yi)家銷售進(jin)口機電產(chan)品(pin)備(bei)(bei)件的國(guo)際貿(mao)易公(gong)司,在德國(guo),美國(guo),等歐洲工(gong)業國(guo)設立采購中心。

我公司有的營銷團隊,可滿足不同行業用戶的需求,只要您(nin)提(ti)供產品名稱、型號及規格、我們都能為您(nin)買(mai)到(dao),并送貨到(dao)您(nin)手上。

我(wo)公司(si)供應產品涵蓋,主要(yao)包括:傳感器(qi)(qi)、編碼器(qi)(qi)、繼電(dian)器(qi)(qi)、控制器(qi)(qi)、開關(guan)、插(cha)(cha)頭(tou)插(cha)(cha)座、電(dian)纜、電(dian)機、液壓(ya)缸、液壓(ya)泵、液壓(ya)閥(fa)、氣缸、氣動(dong)閥(fa)、壓(ya)力表及各種機床及成套設備等(deng)用于于冶金、造紙、礦山、石(shi)化、能源、汽車、水利、市政(zheng)工程及環保等(deng)工業領域(yu)。

驅動器和控(kong)制(zhi)器是(shi)不同的驅動器的功(gong)能,控(kong)制(zhi)器是(shi)專(zhuan)門發(fa)送脈(mo)沖信號給驅動器的。

步進電機控制器與驅動器不同作用

1、步(bu)進(jin)電(dian)機(ji)控制器是一(yi)種能夠(gou)發出平均脈(mo)沖(chong)信(xin)(xin)號(hao)的電(dian)子產品,它發出的信(xin)(xin)號(hao)進(jin)入步(bu)進(jin)電(dian)機(ji)驅(qu)動(dong)器后,會由驅(qu)動(dong)器轉換成步(bu)進(jin)電(dian)機(ji)所需要的強電(dian)流(liu)信(xin)(xin)號(hao),帶動(dong)步(bu)進(jin)電(dian)機(ji)運轉。

2、步(bu)進(jin)(jin)電(dian)(dian)機在控制(zhi)系(xi)統中(zhong)具有廣泛(fan)的應用(yong)(yong)。它可以(yi)把(ba)脈沖(chong)信號轉換成角(jiao)位移,并且可用(yong)(yong)作電(dian)(dian)磁(ci)制(zhi)動(dong)輪、電(dian)(dian)磁(ci)差(cha)分(fen)器(qi)、或角(jiao)位移發生(sheng)器(qi)等。驅動(dong)器(qi)說接收的是(shi)脈沖(chong)信號,每收到一(yi)個脈沖(chong),步(bu)進(jin)(jin)電(dian)(dian)機控制(zhi)器(qi)會帶動(dong)電(dian)(dian)機轉過一(yi)個固(gu)定的角(jiao)度,這由于這個特點,步(bu)進(jin)(jin)電(dian)(dian)機才(cai)會被廣泛(fan)的應用(yong)(yong)到現在的各個行(xing)業里(li)。

3、步進電(dian)(dian)(dian)(dian)機(ji)驅(qu)(qu)動(dong)(dong)器(qi)是一(yi)種將電(dian)(dian)(dian)(dian)脈沖轉(zhuan)化為(wei)(wei)角(jiao)位移的(de)(de)(de)執行(xing)機(ji)構。當步進驅(qu)(qu)動(dong)(dong)器(qi)接收到一(yi)個脈沖信號(hao),它就(jiu)驅(qu)(qu)動(dong)(dong)步進電(dian)(dian)(dian)(dian)機(ji)按(an)設定(ding)的(de)(de)(de)方向轉(zhuan)動(dong)(dong)一(yi)個固定(ding)的(de)(de)(de)角(jiao)度(du)(du)(稱為(wei)(wei)“步距(ju)角(jiao)"),它的(de)(de)(de)旋轉(zhuan)是以固定(ding)的(de)(de)(de)角(jiao)度(du)(du)一(yi)步一(yi)步運行(xing)的(de)(de)(de)。可(ke)(ke)以通(tong)過控制脈沖個數來(lai)控制角(jiao)位移量,從而達(da)到準確定(ding)位的(de)(de)(de)目(mu)(mu)的(de)(de)(de);同時可(ke)(ke)以通(tong)過控制脈沖頻率來(lai)控制電(dian)(dian)(dian)(dian)機(ji)轉(zhuan)動(dong)(dong)的(de)(de)(de)速度(du)(du)和(he)加速度(du)(du),從而達(da)到調速和(he)定(ding)位的(de)(de)(de)目(mu)(mu)的(de)(de)(de)。步進電(dian)(dian)(dian)(dian)機(ji)驅(qu)(qu)動(dong)(dong)器(qi)的(de)(de)(de)原理,采用(yong)單極性直流電(dian)(dian)(dian)(dian)源供(gong)電(dian)(dian)(dian)(dian)。只要對(dui)步進電(dian)(dian)(dian)(dian)機(ji)的(de)(de)(de)各相繞組(zu)按(an)合(he)適的(de)(de)(de)時序通(tong)電(dian)(dian)(dian)(dian),就(jiu)能使步進電(dian)(dian)(dian)(dian)機(ji)步進轉(zhuan)動(dong)(dong)。電機驅動器的(de)作用是什么

直流(liu)有刷電(dian)機(ji)運(yun)行平穩起(qi)制動效果好為(wei)了延長伺服系(xi)統(tong)的(de)工作壽命,對于系(xi)統(tong)的(de)使用環(huan)(huan)境,需要考(kao)慮溫度(du)(du)(du)、濕度(du)(du)(du)、粉塵、振動及輸入電(dian)壓這五個要素,電(dian)機(ji)驅動器的(de)作用 上位機(ji)的(de)指(zhi)令脈(mo)沖(chong)輸入(和內部脈(mo)沖(chong)量給(gei)定)與來(lai)自(zi)編碼器的(de)位置反饋脈(mo)沖(chong),通(tong)(tong)過(guo)位置比較環(huan)(huan)的(de)計(ji)算獲得(de)位置偏差(cha)信號,位置偏差(cha)信號經過(guo)位置控制器的(de)處理(通(tong)(tong)常(chang)為(wei)P比例調節(jie))在特殊情況下,也有選擇(ze)Pl比例積分調節(jie))生成速(su)度(du)(du)(du)環(huan)(huan)的(de)速(su)度(du)(du)(du)給(gei)定指(zhi)令信號,在通(tong)(tong)過(guo)速(su)度(du)(du)(du)控制數和電(dian)流(liu)控制器去控制電(dian)機(ji)的(de)轉速(su)。

位(wei)置偏差量(liang)(liang)在轉(zhuan)速換成速度(du)給定(ding)(ding)指令過(guo)程中,其(qi)速度(du)給定(ding)(ding)指令的大(da)(da)小(xiao)由位(wei)置比(bi)例(li)(li)增益參(can)數kp來規定(ding)(ding),因此,kp參(can)數設定(ding)(ding)越(yue)大(da)(da),控(kong)制(zhi)反應越(yue)迅速,成為(wei)(wei)剛性(xing)比(bi)較硬,反之,剛性(xing)比(bi)較軟(即反應慢)脈沖偏差易經過(guo)位(wei)置控(kong)制(zhi)器(qi)(qi)(qi)(qi)乘上比(bi)例(li)(li)增加常數kp,轉(zhuan)變為(wei)(wei)速度(du)給定(ding)(ding)指令,所以說位(wei)置控(kong)制(zhi)器(qi)(qi)(qi)(qi)就是一個(ge)比(bi)例(li)(li)控(kong)制(zhi)器(qi)(qi)(qi)(qi)。閘機(ji)控(kong)制(zhi)器(qi)(qi)(qi)(qi)功(gong)率電機(ji)驅動(dong)(dong)器(qi)(qi)(qi)(qi)需要具備充分的保護功(gong)能,如(ru)防(fang)止(zhi)因電源電壓降低(di)而引(yin)起(qi)誤動(dong)(dong)作的功(gong)能等(deng)。伺服(fu)驅動(dong)(dong)器(qi)(qi)(qi)(qi)使用方法大(da)(da)體和變頻(pin)器(qi)(qi)(qi)(qi)一樣,在這里需要注意(yi)的是伺服(fu)驅動(dong)(dong)器(qi)(qi)(qi)(qi)的選型不只有(you)功(gong)率一個(ge)參(can)數,還有(you)低(di)慣(guan)量(liang)(liang)和高(gao)慣(guan)量(liang)(liang),低(di)慣(guan)量(liang)(liang)類型一般轉(zhuan)矩低(di),轉(zhuan)速高(gao),適合一些負載(zai)輕,運動(dong)(dong)頻(pin)繁的控(kong)制(zhi)。高(gao)慣(guan)量(liang)(liang)類型轉(zhuan)矩高(gao),轉(zhuan)速低(di),適合一些負載(zai)較大(da)(da)的控(kong)制(zhi)。所以需要根(gen)據現場情況(kuang)選擇(ze)適合驅動(dong)(dong)器(qi)(qi)(qi)(qi),
