全闭环允许旋转电机的位置环，通过直接安装在负载上的附加旋转编码器来闭合。这提高了可重复性和准确性，但对提高刚性、稳定时间和磨损没有太大作用。

稳定时间对机器的影响

实际上，机器可能会由于稳定时间性能不佳而浪费钱，在伺服电机选型过程中很少会考虑这一点。在图 14所示的装置中，具有相似功率容量的直接驱动电机和齿轮电机，以相同的运动曲线运行相同的负载。

行星齿轮减速比为 50:1，额定间隙小于5弧分。移动曲线要求两个电机在接近其峰值扭矩额定值时加速和减速，并且 RMS 扭矩刚好低于连续额定值。两台电机都经过调谐，直到电机编码器测量的稳定时间接近 50 毫秒。在两个装置中，外部环形编码器都安装在负载上，以从外部测量负载位置以进行分析。这揭示了由齿轮电机驱动负载中的振荡，否则电机的编码器看不到这些。
