A study on an air-gap control system in a rotary small-scale model of a Linear Induction Motor for a railway propulsion system
In general, it is important to operate the air-gap length uniformly for improving the system efficiency independent of the flatness of the reaction plate in a railway propulsion system by a linear induction motor(LIM). And it is possible to operate the LIM propulsion system efficiently without a change of the LIM capacity through the air-gap length control on the sloped rail. So, in this research, authors introduce an airgap control system to control the air-gap length which depends on the flatness of the secondary reaction plate when the LIM is operated, and designs a rotary small-scaled LIM and its air-gap control system before manufacturing the real system. Then, authors analyze some characteristics of the LIM (thrust and normal force, input current, efficiency and power factor), and through the LIM control modeling, authors finally analyze an effect of the air-gap-length control of the LIM by the air-gap control system.
