電磁式振動盤的工作原理：

振動(dong)(dong)盤(pan)(pan)是由振動(dong)(dong)板,電(dian)磁(ci)鐵(tie)(tie),銜(xian)鐵(tie)(tie),彈(dan)(dan)簧片(pian),安裝座,減振膠墊(dian)組成,利用控(kong)制(zhi)器產(chan)生(sheng)與系統固有頻(pin)率相同的(de)(de)脈沖電(dian)流使(shi)電(dian)磁(ci)鐵(tie)(tie)勵磁(ci)后,系統發生(sheng)共振,銜(xian)鐵(tie)(tie)及振動(dong)(dong)板會快速的(de)(de)拉向電(dian)磁(ci)鐵(tie)(tie),因為(wei)下降速度很快,所以物(wu)(wu)料(liao)會浮在(zai)(zai)空中(zhong),并(bing)在(zai)(zai)重力作用下落向料(liao)盤(pan)(pan),接著在(zai)(zai)彈(dan)(dan)簧片(pian)的(de)(de)作用下,銜(xian)鐵(tie)(tie)及振動(dong)(dong)板又被推回(hui),這時使(shi)料(liao)盤(pan)(pan)內的(de)(de)物(wu)(wu)料(liao)向前方(fang)移動(dong)(dong),該(gai)作用以每分鐘(zhong)3000---10000次或更(geng)高的(de)(de)次數反復進行,使(shi)用權料(liao)盤(pan)(pan)內的(de)(de)物(wu)(wu)料(liao)平滑移動(dong)(dong).

交流電(dian)(dian)(dian)(dian)壓使電(dian)(dian)(dian)(dian)磁(ci)鐵(tie)產生磁(ci)場,由于頻率很高,故產生的(de)磁(ci)力(li)也是瞬間(jian)變(bian)化(hua)的(de),底盤下面有3---6組一定的(de)角(jiao)度彈(dan)簧片,當電(dian)(dian)(dian)(dian)磁(ci)鐵(tie)同(tong)交流電(dian)(dian)(dian)(dian)瞬間(jian)產生磁(ci)場,彈(dan)簧片受(shou)壓,當電(dian)(dian)(dian)(dian)壓正(zheng)弦(xian)波變(bian)化(hua)的(de)時候,彈(dan)簧片彈(dan)回來,就產生了(le)力(li).
