一般的减速机有斜齿轮减速机(包括平行轴斜齿轮减速机、蜗轮减速机、锥齿轮减速机等等)、行星齿轮减速机、摆线针轮减速机、蜗轮蜗杆减速机、行星摩擦式机械无级变速机等等。
当电机和减速机间装配时同心度保证的非常好时，电机输出轴承受的仅仅是转动力，运转时也会很平滑。然而不同心时，输出轴要承受来自于减速机输入端的径向力，这个径向力长期作用将会使电机输出轴被迫弯曲，而且弯曲的方向随着输出轴转动不断变化。输出轴每转动一周，横向力的方向变化360度。如果同心度的误差较大时，该径向力使电机输出轴温度升高，其金属结构不断被破坏，最后该径向力将会超出电机输出轴所能承受的径向力，最后导致驱动电机输出轴折断。
当减速机同心度的误差越大时，驱动电机输出轴折断的时间越短。在驱动电机输出轴折断的同时，减速机输入端同样也会承受来自于电机方面的径向力，如果这个径向力同时超出了二者所能承受的最大径向负荷的话，其结果也会导致减速机输入端产生变形甚至断裂。因此，在装配时保证同心度至关重要。
