Although, Single-Sided Linear Induction Motor (SLIM) utilization has increased in railway applications due to their numerous advantages in comparison to Rotational Induction Motors (RIM), there are some sophistication in their mathematical models and electrical drive. This paper focuses on the problems of SLIM modeling, with assuming end-effect on the basis of Field Oriented Control (FOC) as a ...
Input frequency is one of the important variables in design and performance analysis of single-sided linear induction motors (SLIMs). Changing the frequency changes both the dimension of the SLIM in design process and the performance of the designed motor. The frequency influences the induced eddy currents in the secondary sheet as well as saturation level of the secondary back-iron. In this pa...

The linear Induction motor, first conceived in the 19 century, could present a viable solution to the problem of quick and efficient transportation. However the performance of Single Sided Linear Induction Motor (SLIM) is severely degraded by ‘end effects’ and ‘transverse edge effects’. The present work is an attempt to investigate the magnetic flux distribution within the air gap and other reg...
Linear induction motors have single and double-sided structures which are used in special applications, according to their advantages and disadvantages. Due to advantages such as lack of normal forces in double-sided type, these motors are more controllable and popular than the single-sided type, especially for transportation applications. In literature, single-sided linear induction motors ha...
This paper proposes a new sliding mode control (SMC) based model reference adaptive system (MRAS) for sensorless indirect field oriented control (IFOC) of a single-sided linear induction motor (SLIM). The operation of MRAS speed estimators dramatically depends on adaptation mechanism. Fixed-gain PI controller is conventionally used for this purpose which may fail to estimate the speed correctl...
The secondary back-iron plays important role in performance of single-sided linear induction motors (SLIMs). On one hand, it provides a return path for the primary flux; on the other hand, it is employed as a mechanical support for the secondary sheet. The conductivity of the iron used in the back-iron as well as its magnetic permeability influence the outputs of the machine, while the magnetic...
