摘　　要：用1 台驱动器同时驱动2 台步进电动机构成双电动机单元,2 台电动机间具有相同转速相同角位移,即良好的同步性能,有实际应用价值。文中介绍2 台电动机的不同接法,电动机和驱动器的配置等基本问题,并分析了2台电动机负载不平衡情况的运行特点,得出了并联接法的抗不平衡负载和过载能力较好的结论。One driver is driving two stepping motors synchronously is called STEP DRIVING UNIT WITH TWO MOTORS. Two motors in such unit have the same angle velocity and the same angle displacement. It means two motors have good synchronism, which is valuable for applications. The fundamental considerations like various ways of motor connections, the equibalent configuration of motors and driver are presented.It also including the operational characteristics in case of unbalanced-load between two motors. The conclusion that parallel-connection unit has the advantage of better anti-unbalanced load and overload capability.
