　A linear motor attracts attention as a driving source for long-distance transportation system in the vast factory. This system is asked for a high acceleration, a high deceleration, a large thrust and a good controllability. Working process of the products are scattered in a multiple areas, the conveyance of the products between the process is important. When moving the products to the next processing, the mover is stopped. Then is unloaded the product from the mover. Also, the product is loaded on the mover that is moved to next processing. Thus, the mover repeats the “Stop and Go” which leads to a decrease in transport efficiency. This paper reports a parallel synchronous drive method for transportation system of PM-LSM. This method synchronizes the mover of the two LSMs. One assumes the main-line connecting the inter-processes and the other assumes the sub-line of each processing. Because both movers in the synchronized state is the same inertia, conveyance material may be moved without the mover stops. We tested the various driving of this method by simulation.
