振動(dòng)電機(jī)、振動(dòng)馬達(dá)、震動(dòng)電機(jī)都屬于三相異步振動(dòng)源電動(dòng)機(jī)，和普通電機(jī)的原理一樣都是通過繞組來帶動(dòng)，而振動(dòng)電機(jī)、振動(dòng)馬達(dá)、震動(dòng)電機(jī)都是在普通電機(jī)的兩端加上偏心塊，通過帶動(dòng)兩端偏心塊振動(dòng)物料，同時(shí)振動(dòng)電機(jī)、振動(dòng)馬達(dá)、震動(dòng)電機(jī)都可以通過調(diào)節(jié)兩端偏心塊來調(diào)節(jié)激振力的大小。
振動(dòng)電機(jī)在使用中會(huì)出現(xiàn)各種各樣的問題，在這些問題中，由于用戶不懂得振動(dòng)電機(jī)或者振動(dòng)篩的安裝和使用方法而造成的故障占大多數(shù)。震動(dòng)電機(jī)的生產(chǎn)時(shí)，軸和軸承的配合間隙就和普通電機(jī)是不一樣的，普通電機(jī)的軸和軸承之間一定要緊密配合，而振動(dòng)電機(jī)中軸和軸承的配合間隙是滑動(dòng)配合。振動(dòng)電機(jī)是靠自身的高頻震動(dòng)產(chǎn)生震動(dòng)力，同功率的震動(dòng)電機(jī)的轉(zhuǎn)子軸比普通電機(jī)粗。這就是主要區(qū)別。震動(dòng)電機(jī)散熱不好，使用壽命低于普通電機(jī)，但安裝簡(jiǎn)單。其實(shí)在振動(dòng)電機(jī)的生產(chǎn)時(shí)，軸和軸承的配合間隙就和普通電機(jī)是不一樣的，普通電機(jī)的軸和軸承之間一定要緊密配合，而振動(dòng)電機(jī)中軸和軸承的配合間隙是滑動(dòng)配合，中間存在的間隙，在維修時(shí)當(dāng)然會(huì)感覺軸會(huì)產(chǎn)生左右串動(dòng)。其實(shí)這個(gè)間隙配合是有著它的重要作用的。一方面，一臺(tái)圓形電機(jī)，圓周機(jī)械角度恒等于360°，而其電角度的大小則與極對(duì)數(shù)p有關(guān)，圓周總的電角度為p*360°。從這一概念來看，多極旋變(精機(jī))已將有限的機(jī)械角度放大了p倍，即在精機(jī)有勵(lì)磁的情況下，即使定、轉(zhuǎn)子之間僅有微小的相對(duì)角度位移，其輸出電信號(hào)的幅值也會(huì)有顯著變化，這就提高了機(jī)械角位移的分辨力。
另一方面，從微分學(xué)概念來看，任何一個(gè)圓可理解為由若干非常短的線段組成，多極旋變的極對(duì)數(shù)越大，受齒、槽、氣隙不均等因素的影響就越小，就可以達(dá)到非常高的角位移精度，即工藝誤差、磁路不對(duì)稱會(huì)隨旋變極對(duì)數(shù)的增大而被分割。極對(duì)數(shù)越大，誤差分割得越小，多極旋變的精度也就越高。前面介紹了采用電磁增角法提高旋變精度的原理，在實(shí)際工作中也可用機(jī)械增角法提高旋變精度。即用齒輪增速原理將兩臺(tái)同型號(hào)1對(duì)極旋變嚙合起來，類似一臺(tái)雙通道多極旋變，稱為機(jī)械增角旋變，早期應(yīng)用的就是這種結(jié)構(gòu)形式的多極旋變。其中，低速主動(dòng)輪旋變類似目前雙通道多極旋變的粗機(jī)，高速從動(dòng)輪旋變類似于精機(jī)，增速比等效于極對(duì)數(shù)。在忽略齒輪分度和嚙合誤差影響的前提下，機(jī)械增角旋變的分辨力可隨增速比n提高n倍，精度也可隨之提高。
