Analysis of the Frequency Effects on Design and Back-Iron Characteristics of Double-Layer Secondary Single-Sided Linear Induction Motors
Authors
Abstract:
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 paper, the effect of the input frequency on the dimensions of the SLIM is investigated in the design process. Then, the frequency effects on the magnetic characteristics of the secondary back-iron as well as the SLIM performance are analyzed for a designed motor. Finally, the analytical results are confirmed by 2D time-stepping finite element method.

full textDesign Optimization and Construction of Double-Sided Linear Induction Motor
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...

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...
