电机的

Over the years various kinds of both bench and stand-mounted countershafts were available: one model of bench countershaft featured a four-step final-drive pulley with a "fast-and-loose" drive from the motor (which gave the effect of a clutch) whist the other dispensed with this arrangement and was driven directly from the motor by what the makers described as a " special joined V-belt ".

多年来各种都替补和备用安装countershafts有：一种模式的板凳副轴功能的四步最后驱动滑轮的"快速和宽松"的电机驱动器惠其他免除这一安排，并直接驱动电机的制造商所形容为"特别加入V带"。
