電磁式振動盤的工作原理：

振動(dong)(dong)盤(pan)是由振動(dong)(dong)板(ban),電(dian)(dian)磁(ci)鐵(tie),銜鐵(tie),彈簧(huang)片(pian)(pian),安裝座,減(jian)振膠墊組成,利用(yong)(yong)(yong)控制(zhi)器(qi)產生與系(xi)統固有頻(pin)率相同的(de)脈沖(chong)電(dian)(dian)流使(shi)電(dian)(dian)磁(ci)鐵(tie)勵磁(ci)后(hou),系(xi)統發(fa)生共振,銜鐵(tie)及振動(dong)(dong)板(ban)會快速的(de)拉向(xiang)(xiang)電(dian)(dian)磁(ci)鐵(tie),因為下(xia)(xia)降速度(du)很快,所(suo)以物(wu)料(liao)(liao)會浮(fu)在空中,并(bing)在重力作(zuo)用(yong)(yong)(yong)下(xia)(xia)落向(xiang)(xiang)料(liao)(liao)盤(pan),接(jie)著在彈簧(huang)片(pian)(pian)的(de)作(zuo)用(yong)(yong)(yong)下(xia)(xia),銜鐵(tie)及振動(dong)(dong)板(ban)又被推回,這時使(shi)料(liao)(liao)盤(pan)內(nei)的(de)物(wu)料(liao)(liao)向(xiang)(xiang)前方移動(dong)(dong),該作(zuo)用(yong)(yong)(yong)以每分鐘3000---10000次或更高的(de)次數反復進行,使(shi)用(yong)(yong)(yong)權料(liao)(liao)盤(pan)內(nei)的(de)物(wu)料(liao)(liao)平滑移動(dong)(dong).

交流電(dian)(dian)壓(ya)使電(dian)(dian)磁(ci)(ci)鐵產生(sheng)(sheng)磁(ci)(ci)場,由于(yu)頻(pin)率很高(gao),故產生(sheng)(sheng)的(de)(de)磁(ci)(ci)力也是(shi)瞬間變(bian)(bian)化的(de)(de),底盤(pan)下面有(you)3---6組一(yi)定的(de)(de)角(jiao)度彈簧片,當電(dian)(dian)磁(ci)(ci)鐵同交流電(dian)(dian)瞬間產生(sheng)(sheng)磁(ci)(ci)場,彈簧片受(shou)壓(ya),當電(dian)(dian)壓(ya)正(zheng)弦(xian)波變(bian)(bian)化的(de)(de)時候(hou),彈簧片彈回來,就產生(sheng)(sheng)了力.
