振動電機的運動軌跡主要有下面幾種：
1）圓或橢圓振動：振動體的振動軌跡在水平面上的投影是一條直線，而在垂直面上的投影為一個圓或橢圓的振動形式稱為圓或橢圓型振動。通常將一臺振動電機安裝在振動機械機體上，即可產生圓形或橢圓形的振動。這種運動發生在與振動電機轉軸相垂直的平面上，其形式則主要由振動電機與整機重心的相對位置而定。
2）旋(xuan)(xuan)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)：振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)體(ti)的(de)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)軌跡(ji)(ji)在(zai)(zai)水平面上(shang)(shang)(shang)的(de)投影(ying)是圓(yuan)或橢圓(yuan)，這種振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)形式(shi)稱為旋(xuan)(xuan)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)。旋(xuan)(xuan)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)又可以分(fen)為復(fu)旋(xuan)(xuan)型(xing)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)、渦旋(xuan)(xuan)型(xing)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)、平旋(xuan)(xuan)型(xing)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)三種形式(shi)。當振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)體(ti)的(de)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)軌跡(ji)(ji)在(zai)(zai)垂直(zhi)(zhi)面上(shang)(shang)(shang)的(de)投影(ying)為一(yi)圓(yuan)或橢圓(yuan)者(zhe)，其振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)形式(shi)稱為復(fu)旋(xuan)(xuan)型(xing)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)；當振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)體(ti)的(de)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)軌跡(ji)(ji)在(zai)(zai)垂直(zhi)(zhi)面上(shang)(shang)(shang)的(de)投影(ying)為一(yi)斜直(zhi)(zhi)線(xian)(xian)時，其振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)形式(shi)稱為渦旋(xuan)(xuan)型(xing)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)；當振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)體(ti)的(de)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)軌跡(ji)(ji)在(zai)(zai)垂直(zhi)(zhi)面上(shang)(shang)(shang)的(de)投影(ying)為一(yi)水平直(zhi)(zhi)線(xian)(xian)時，其振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)形式(shi)稱為平旋(xuan)(xuan)型(xing)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)。通常由(you)(you)立式(shi)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)電機(ji)激(ji)振(zhen)(zhen)(zhen)(zhen)(zhen)的(de)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)械產(chan)生(sheng)旋(xuan)(xuan)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)，其振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)形式(shi)由(you)(you)立式(shi)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)電機(ji)兩端激(ji)振(zhen)(zhen)(zhen)(zhen)(zhen)塊的(de)夾角而(er)定(ding)。也(ye)可將兩臺臥(wo)式(shi)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)電機(ji)安(an)裝在(zai)(zai)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)設備的(de)兩側(ce)，使其轉軸呈(cheng)一(yi)設定(ding)的(de)角度，則振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)械也(ye)將產(chan)生(sheng)旋(xuan)(xuan)振(zhen)(zhen)(zhen)(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)。
