Abstract
Transportation systems are used in the field of the Factory Automation (FA) and Logistics for reduce their costs. Currently, rotating machines are used for the drive sources of the transportation system with mechanical conversion systems. The systems are required for the faster, useful and easy operations. These systems are not capable enough to satisfy these requirements. We think that the permanent magnet type linear synchronous motor (PM-LSM) is used for the power sources of the transportation system. In usual, the stator of the LSM is arranged continuously all over the guideway. Therefore, the cost of the transportation system is risen up. So we proposed that the discontinuously arrangement of the stator for transportation system using PM-LSM. The discontinuous arrangement systems with PM-LSM need some technological breakthroughs.
In this paper, we describe the results of the study to realize the discontinuously arranged PM-LSM for transportation system. At first, we study the effect of the magnetic attraction force between iron core of the primary and magnets of the secondary. Next we proposed a simple synchronizing method and try to synchronize by experiments. At last, we describe the limit of the synchronization of the proposed method.
