一般的減速機有斜齒輪減速機(包括平行軸斜齒輪減速機、蝸輪減速機、錐齒輪減速機等等)、行星齒輪減速機、擺線針輪減速機、蝸輪蝸桿減速機、行星摩擦式機械無級變速機等等。
當電機和減速機間裝配時同心度保證的非常好時，電機輸出軸承受的僅僅是轉動力，運轉時也會很平滑。然而不同心時，輸出軸要承受來自于減速機輸入端的徑向力，這個徑向力長期作用將會使電機輸出軸被迫彎曲，而且彎曲的方向隨著輸出軸轉動不斷變化。輸出軸每轉動一周，橫向力的方向變化360度。如果同心度的誤差較大時，該徑向力使電機輸出軸溫度升高，其金屬結構不斷被破壞，最后該徑向力將會超出電機輸出軸所能承受的徑向力，最后導致驅動電機輸出軸折斷。
當減速機同心度的誤差越大時，驅動電機輸出軸折斷的時間越短。在驅動電機輸出軸折斷的同時，減速機輸入端同樣也會承受來自于電機方面的徑向力，如果這個徑向力同時超出了二者所能承受的最大徑向負荷的話，其結果也會導致減速機輸入端產生變形甚至斷裂。因此，在裝配時保證同心度至關重要。
