Mechanical Unbalance Characteristics Analysis of Linear Motor for Magrntically Levitated Transit

In this study, a variety of characteristics were shown experimentally under mechanically unbalnced states expected in a practicl system that linear motor is used as a driving motor of magneticlly levitated transit and the design criterion of the linear motor has been proposed. Since, with slip being at 0.1, end effect was reduced a little to increase thrust about 6.14 percents in case thatsinusoidal current conducted 5[A] in short coil at each end of linear motor for compensation of it, if the ratio of sinusoidl current versus input currents is adjusted properly, it is thought that this method small be effective one. And if the gap of exit region is bigger than that of entry region, end effect will be reduced. As a result, more effective driving will be obtained.
