電磁式振動盤的工作原理：

振(zhen)動(dong)(dong)(dong)盤(pan)是由振(zhen)動(dong)(dong)(dong)板(ban),電(dian)磁鐵(tie)(tie),銜鐵(tie)(tie),彈簧片(pian),安裝座,減振(zhen)膠(jiao)墊組成,利用(yong)控制器(qi)產生(sheng)與系統固(gu)有頻率相同(tong)的(de)(de)(de)脈(mo)沖電(dian)流使電(dian)磁鐵(tie)(tie)勵磁后,系統發生(sheng)共振(zhen),銜鐵(tie)(tie)及振(zhen)動(dong)(dong)(dong)板(ban)會快速的(de)(de)(de)拉向(xiang)(xiang)電(dian)磁鐵(tie)(tie),因為下降速度很快,所以(yi)物(wu)料(liao)會浮(fu)在空中,并(bing)在重力(li)作(zuo)用(yong)下落(luo)向(xiang)(xiang)料(liao)盤(pan),接著在彈簧片(pian)的(de)(de)(de)作(zuo)用(yong)下,銜鐵(tie)(tie)及振(zhen)動(dong)(dong)(dong)板(ban)又被推回,這(zhe)時使料(liao)盤(pan)內(nei)的(de)(de)(de)物(wu)料(liao)向(xiang)(xiang)前方移動(dong)(dong)(dong),該(gai)作(zuo)用(yong)以(yi)每分鐘(zhong)3000---10000次或(huo)更高的(de)(de)(de)次數(shu)反復(fu)進行,使用(yong)權料(liao)盤(pan)內(nei)的(de)(de)(de)物(wu)料(liao)平滑移動(dong)(dong)(dong).

交(jiao)流(liu)電(dian)(dian)壓使(shi)電(dian)(dian)磁(ci)鐵產(chan)生(sheng)(sheng)磁(ci)場(chang),由于頻率很高,故(gu)產(chan)生(sheng)(sheng)的磁(ci)力也是瞬(shun)(shun)間(jian)變(bian)化(hua)的,底盤下面(mian)有3---6組一定的角度彈簧(huang)片(pian),當電(dian)(dian)磁(ci)鐵同交(jiao)流(liu)電(dian)(dian)瞬(shun)(shun)間(jian)產(chan)生(sheng)(sheng)磁(ci)場(chang),彈簧(huang)片(pian)受壓,當電(dian)(dian)壓正(zheng)弦波變(bian)化(hua)的時候,彈簧(huang)片(pian)彈回來(lai),就(jiu)產(chan)生(sheng)(sheng)了力.
