Now commonly used servo motor is ac servo motor, the axial end in motor with photoelectric encoder, by examining the rotor Angle to frequency conversion control.
目前常用的伺服电机是交流伺服电机，在电机的轴端装有光电编码器，通过检测转子角度用以变频控制。

To avoid this from happening, we have to study the axial displacement motor rotor and how to measure it to better control it.
为了避免这种情况的发生，我们要研究电机转子的轴向位移以及如何测量它以更好的控制它。

Practices demonstrate that blocking balance hole is a effective method to resolve the axial negative thrust of rotor.
