Due to their low speeds and limited Battery range were not drawbacks, and the cars became popular for their quietness and low maintenance costs.
因为电瓶车的速度低，一次充电的行程有限，但它们的低噪音、维修费低，特别受欢迎。
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。
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。
