電磁式振動盤的工作原理：

振(zhen)動(dong)(dong)盤是(shi)由振(zhen)動(dong)(dong)板(ban)(ban),電(dian)(dian)磁(ci)(ci)鐵,銜鐵,彈簧(huang)片,安(an)裝座,減(jian)振(zhen)膠墊組成(cheng),利用(yong)控制器產生與系統(tong)固有頻率相同(tong)的(de)(de)(de)脈(mo)沖電(dian)(dian)流使(shi)電(dian)(dian)磁(ci)(ci)鐵勵磁(ci)(ci)后,系統(tong)發生共振(zhen),銜鐵及振(zhen)動(dong)(dong)板(ban)(ban)會快速的(de)(de)(de)拉向電(dian)(dian)磁(ci)(ci)鐵,因為下降速度很快,所(suo)以物(wu)(wu)料會浮在空(kong)中(zhong),并(bing)在重力(li)作用(yong)下落向料盤,接著在彈簧(huang)片的(de)(de)(de)作用(yong)下,銜鐵及振(zhen)動(dong)(dong)板(ban)(ban)又被(bei)推(tui)回,這時使(shi)料盤內(nei)的(de)(de)(de)物(wu)(wu)料向前方移(yi)動(dong)(dong),該作用(yong)以每分鐘(zhong)3000---10000次(ci)或更高的(de)(de)(de)次(ci)數(shu)反復進行(xing),使(shi)用(yong)權料盤內(nei)的(de)(de)(de)物(wu)(wu)料平滑移(yi)動(dong)(dong).

交流電壓使(shi)電磁鐵產生(sheng)磁場(chang),由于頻率很高,故產生(sheng)的(de)磁力也是瞬間變化(hua)的(de),底盤下面有3---6組一定的(de)角度彈簧片(pian),當(dang)電磁鐵同交流電瞬間產生(sheng)磁場(chang),彈簧片(pian)受壓,當(dang)電壓正(zheng)弦波變化(hua)的(de)時候,彈簧片(pian)彈回來,就產生(sheng)了力.
