Abstract :
Linear motors have many applications because of their unique characteristic which are different from rotary machines. In particular, Linear Induction Motors (LIMs) have a simple and strong structure, a flexible mechanism, and so on. The most popular application of LIMs is in transportation systems. It is important to investigate the dynamic characteristics of LIMs in order for them to be successfully applied in transportation systems. However, it is difficult to measure the dynamic characteristics of LIMs. Long enough span or large enough diameter of a cylindrical drum is necessary for the secondary side in the ordinary measurement system. In this paper, the use of a disc-shaped secondary side to measure the dynamic characteristics of LIMs are proposed. The rotating dynamic characteristics of disc-shaped LIMs are converted into linear motion.
