電(dian)(dian)(dian)(dian)(dian)磁振(zhen)動(dong)(dong)給料(liao)機(ji)(ji)是一(yi)個(ge)(ge)較為完整的(de)(de)(de)(de)(de)雙質點定(ding)向強迫振(zhen)動(dong)(dong)的(de)(de)(de)(de)(de)彈(dan)性系(xi)統， 整個(ge)(ge)系(xi)統工作(zuo)(zuo)在低(di)臨界共振(zhen)狀態，主(zhu)(zhu)要利用電(dian)(dian)(dian)(dian)(dian)磁激振(zhen)器驅(qu)動(dong)(dong)槽(cao)體(ti)以一(yi)定(ding)的(de)(de)(de)(de)(de)傾角做往(wang)復振(zhen)動(dong)(dong)，使物料(liao)沿槽(cao)移動(dong)(dong)。圖 2(a)為電(dian)(dian)(dian)(dian)(dian)磁振(zhen)動(dong)(dong)給料(liao)機(ji)(ji)的(de)(de)(de)(de)(de)工作(zuo)(zuo)原理。物料(liao)2置(zhi)于(yu)由主(zhu)(zhu)振(zhen)彈(dan)簧(huang)(huang)(huang)3支撐的(de)(de)(de)(de)(de)供料(liao)槽(cao)體(ti)1上(shang)(shang)，銜鐵(tie)4 與槽(cao)體(ti)的(de)(de)(de)(de)(de)主(zhu)(zhu)振(zhen)彈(dan)簧(huang)(huang)(huang)連成一(yi)體(ti)，線圈(quan)(quan)6纏(chan)繞在鐵(tie)芯(xin)5上(shang)(shang)。由于(yu)線圈(quan)(quan)中流(liu)過(guo)(guo)的(de)(de)(de)(de)(de)是經過(guo)(guo)半波整流(liu)后(hou)的(de)(de)(de)(de)(de)單(dan)向脈(mo)動(dong)(dong)電(dian)(dian)(dian)(dian)(dian)流(liu)，因此，電(dian)(dian)(dian)(dian)(dian)磁鐵(tie)就產(chan)生(sheng)了相應的(de)(de)(de)(de)(de)脈(mo)沖電(dian)(dian)(dian)(dian)(dian)磁力(li)(li)(如圖 2(b))。在交流(liu)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)正半周，脈(mo)動(dong)(dong)電(dian)(dian)(dian)(dian)(dian)流(liu)流(liu)過(guo)(guo)線圈(quan)(quan)，在鐵(tie)芯(xin)和銜鐵(tie)之間產(chan)生(sheng)一(yi)脈(mo)動(dong)(dong)電(dian)(dian)(dian)(dian)(dian)磁吸力(li)(li)，使槽(cao)體(ti)向后(hou)運動(dong)(dong)，激振(zhen)器的(de)(de)(de)(de)(de)主(zhu)(zhu)彈(dan)簧(huang)(huang)(huang)發生(sheng)變形，儲存勢能;在負半周期內，線圈(quan)(quan)中無電(dian)(dian)(dian)(dian)(dian)流(liu)通過(guo)(guo)，電(dian)(dian)(dian)(dian)(dian)磁力(li)(li)消失，銜鐵(tie)在彈(dan)簧(huang)(huang)(huang)力(li)(li)的(de)(de)(de)(de)(de)作(zuo)(zuo)用下與電(dian)(dian)(dian)(dian)(dian)磁鐵(tie)分開，使料(liao)槽(cao)向前(qian)運動(dong)(dong)，這(zhe)樣料(liao)槽(cao)就以交流(liu)電(dian)(dian)(dian)(dian)(dian)源的(de)(de)(de)(de)(de)頻(pin)率，連續(xu)地(di)進行往(wang)復振(zhen)動(dong)(dong)。                                                                                                                                     

特點

⒈電(dian)磁(ci)振動(dong)(dong)給料(liao)機電(dian)氣控制(zhi)采用半波整流電(dian)路，可(ke)(ke)無級調節給料(liao)量，可(ke)(ke)用于自動(dong)(dong)控制(zhi)的生(sheng)(sheng)產流程中，實現生(sheng)(sheng)產過(guo)程自動(dong)(dong)化。

⒉無轉(zhuan)動零(ling)部件，不需潤滑(hua)，結構簡單，維修方便。

⒊電磁振動給料機物料是微拋運(yun)動，料槽磨損(sun)小。
