Thus, the ac input motor and driver system has superior torque characteristics over a wide speed range, from low to high speeds, offering a large speed ratio.

因此，AC输入电机和驱动系统具有在很宽的转速范围内扭矩特性优越，从低到高的速度，提供了大速比。

They are characterised by constant torque at low speed, and constant power over a wide range of speeds (1:10), achieved by DIGIVEX Drive.

他们的特点是在低速恒转矩和恒功率速度超过了范围广泛（1：10），驱动实现DIGIVEX。
