求翻译：又一次改变直线电机三相电源的接法，电机次级又带动主动活塞一起向左运动，在复位弹簧2作用下，输出活塞2退回到初始状态，完成一个工作循环。是什么意思？

Again to change the linear motor three-phase power connection, but also to drive the secondary active piston motor with the left movement, the role of the return spring 2, the output piston 2 back to its original state, complete a work cycle.

A linear motor 3 change again and again with the connection for the power supply, the electrical sub-piston initiative also led a movement to left, the Reset spring 2role, the output piston 2 back to the original state, completing a cycle of work.

Changes the straight line electrical machinery three-phase power source once again the connection, the electrical machinery secondary leads the driving piston together towards left movement, under the recoil check spring 2 functions, outputs piston 2 to return to the original state, completes an ope

Once again change the method of linear motor with three-phase power, secondary also led an active motor piston with left movements, reset spring under 2, the output of piston 2 returned to its original state, complete a duty cycle.

Again changed three phase power connection of linear motors, motor left with secondary drive the active piston movement, back spring under 2, output 2 piston return to initial state completed a work cycle.
