Early computer's computational speed low and the prevailing scientific computing and data processing is not affected, but can not meet the requirements of real-time control machine.

早期计算机的运算速度低，对当时的科学计算和数据处理影响还不大，但不能适应机床实时控制的要求。

Excellent antifriction capability, can make the machine in low speed vibration or discontinuous sliding reduced to the minimum.

优良的减摩性能，可使机床在低速下将振动或间断滑动减为最小。

The low speed machine usually has a short and fat structure in order to use effectively the rotating speed of the rotor, as contrasted with the long and thin structure of the high speed machine.

由于电机转速很低，为了充分利用其圆周线速度，一般需要采用直径大而轴向长度短的结构，与传统高速电机的细长结构有很大区别。
