中空轴式蜗齿行星减速机加装一个斜齿轮减速器在输入端，组成的减速器可获得非常低的输出速度，是斜齿轮级和蜗齿级的组合，比纯单级蜗轮行星减速机具有更高的效率。而且振动小，噪音低，能耗低。
常见问题及其原因：(1)行星减速机发热和漏油，(2)蜗轮磨损，(3)传动小斜齿轮磨损，(4)轴承(蜗杆处)损坏。
1 行星减速机发热和漏油。蜗轮行星减速机为了提率，一般均采用有色金属做蜗轮，蜗杆则采用较硬的钢材，由于它是滑动磨擦传动，在运行过程中，就会产生较高的热量，使行星减速机各零件和密封之间热膨胀产生差异，从而在各配合面产生间隙，而油液由于温度的升高变稀，容易造成泄漏。主要原因有四点，一是材质的搭配是否合理，二是啮合磨擦面的表面质量，三是润滑油的选择，添加量是否正确，四是装配质量和使用环境。
2 蜗轮磨损。蜗轮一般采用锡青铜，配对的蜗杆材料一般用45钢淬硬至HRC45一55,还常用40C:淬硬HRC50一55，经蜗杆磨床磨削至粗糙度RaO. 8 fcm,行星减速机正常运行时，蜗杆就象一把淬硬的“锉刀”，不停地锉削蜗轮，使蜗轮产生磨损。一般来说，这种磨损很慢，象某厂有些行星减速机可以使用10年以上。如果磨损速度较快，就要考虑行星减速机的选型是否正确，是否有超负荷运行，蜗轮蜗杆的材质，装配质量或使用环境等原因。

当前伺服电机趋向步进化的具体表现：
1、小体积高功效：采用永磁材料及优化电机设计，使体积较小的电机也能产生很大的扭矩。同一型号电机与不同的驱动器匹配时，输出扭矩不同；相同体积电机采用不同绕组形式、不同磁极数时，输出功率也不相同；
2、抗冲击扭矩：扭矩能达到额定扭矩的若干倍；
3、采用高性能的磁性材料，高磁能积；
4、电机和驱动器上均可带有温度监视器。步进电机、步进电机驱动器、无刷电机、无刷电机驱动器。

一旦控制系统有偏差信号，控制绕组就要接受与之相对应的控制电压。在一般情况下，电机内部产生的磁场是椭圆形旋转磁场。一个椭圆形旋转磁场可以看成是由两个圆形旋转磁场合成起来的。这两个圆形旋转磁场幅值不等(与原椭圆旋转磁场转向相同的正转磁场大，与原转向相反的反转磁场小)，但以相同的速度，向相反的方向旋转。它们切割转子绕组感应的电势和电流以及产生的电磁力矩也方向相反、大小不等(正转者大，反转者小)合成力矩不为零，所以伺服电机就朝着正转磁场的方向转动起来，随着信号的增强，磁场接近圆形，此时正转磁场及其力矩增大，反转磁场及其力矩减小，合成力矩变大，如负载力矩不变，转子的速度就增加。如果改变控制电压的相位，即移相180o，旋转磁场的转向相反，因而产生的合成力矩方向也相反，伺服电机将反转。若控制信号消失，只有励磁绕组通入电流，伺服电机产生的磁场将是脉动磁场，转子很快地停下来。
