This paper studies Single-sided linear induction motor (SLIM) which can be used to motivate in a levitation railway transportation system. The rotary motor is cut out and laid flat to form the equivalent linear induction motor. Linear induction motors (LIM) are used in many different applications, from slow moving sliding doors to high-speed trains around the world. The primary goal is to analyze a small laboratory sized single-sided linear induction motor (SLIM) for educational aid. This research describes the design and construction of the 100 W rating stator component of a SLIM. SLIM consists of stator and rotor. The stator can supply 20 V and 5 A. It is built with iron laminations; having 6 poles and wound with a double layer type. The rotor is coated with aluminum and attached with six permanent magnets. This rotor is located on top of the aluminum track. A SLIM model of specified parameters is designed using a user-interactive MATLAB program. The performance curves of the SLIM i.e., thrust and efficiency, are drawn and then analyzed for target thrust and different rated slips. The effect of parameters of the SLIM such as air-gap, thickness of permanent magnet and the number of poles on the performance of SLIM are analyzed and the results are also discussed.
