Abstract: Starting from a brief structural description of single-sided linear induction machines (LIMs), their main applications will be exposed in this lecture with specific reference to MAGLEV (Magnetically Levitation) vehicles, urban people movers (such as linear metro, light railway, etc.), launchers, actuators for industry, etc. As a first step, the main differences between rotating and linear induction motors will be highlighted, focusing on the aspects end effects in details. Design criteria of LIMs will be specifically exposed, emphasizing the main differences with the classic rotating induction motor design, caused by the presence of end effects, large air-gaps, half-filled slots, high leakage inductances, etc.

Afterwards, in order to improve the working efficiency, it will share advancements in the accurate modelling, loss minimization control strategy, multi-objective optimization technique, etc. for LIM and drive. Researchers and engineers from electrical, mechanical and information fields may find this lecture very useful when dealing with transportation motor and drive related design, control, system integration, which can be extended to other industrial applications.
