電磁式振動盤的工作原理：

振(zhen)(zhen)動(dong)盤(pan)是由(you)振(zhen)(zhen)動(dong)板(ban),電(dian)(dian)磁鐵,銜(xian)鐵,彈簧片(pian),安裝座,減振(zhen)(zhen)膠(jiao)墊組(zu)成(cheng),利用(yong)(yong)控制器產生與系統(tong)固有頻率相同的脈沖(chong)電(dian)(dian)流(liu)使(shi)電(dian)(dian)磁鐵勵磁后(hou),系統(tong)發生共振(zhen)(zhen),銜(xian)鐵及振(zhen)(zhen)動(dong)板(ban)會快速的拉向電(dian)(dian)磁鐵,因(yin)為下(xia)降速度(du)很(hen)快,所以物(wu)料(liao)(liao)會浮在空(kong)中,并(bing)在重力作用(yong)(yong)下(xia)落向料(liao)(liao)盤(pan),接著在彈簧片(pian)的作用(yong)(yong)下(xia),銜(xian)鐵及振(zhen)(zhen)動(dong)板(ban)又(you)被推回,這時使(shi)料(liao)(liao)盤(pan)內的物(wu)料(liao)(liao)向前方移動(dong),該(gai)作用(yong)(yong)以每(mei)分(fen)鐘3000---10000次(ci)(ci)或更高(gao)的次(ci)(ci)數反復進行,使(shi)用(yong)(yong)權(quan)料(liao)(liao)盤(pan)內的物(wu)料(liao)(liao)平滑移動(dong).

交流電壓(ya)(ya)使電磁鐵產生磁場,由于頻率很(hen)高,故產生的磁力(li)也是瞬間變化(hua)的,底盤下(xia)面有3---6組一定的角度彈(dan)(dan)簧(huang)片,當電磁鐵同交流電瞬間產生磁場,彈(dan)(dan)簧(huang)片受壓(ya)(ya),當電壓(ya)(ya)正弦波變化(hua)的時候,彈(dan)(dan)簧(huang)片彈(dan)(dan)回來,就(jiu)產生了力(li).
