Design Optimization of a Ladder Secondary Single-Sided Linear Induction Motor for Improved Performance

ABSTRACT:

In this paper, style and optimization of a ladder-kind single-sided linear induction motor (Ladder SLIM) for machine tool applications is investigated. High-speed linear induction machines suffer from the top-result phenomenon, which can cut back the thrust and end in declined output characteristics. Although it's common to contemplate this phenomenon in high-speed applications, it's essential to require it into account in the planning and analysis of low-speed low-air-gap linear machines. Yet, Ladder SLIMs have significant flux density ripples, and using skewed bars for secondary of the machine may be a common answer for it. Thus, providing needed equations, an algorithm for coming up with a Ladder SLIM considering the tip-result phenomenon based mostly on Duncan model is proposed, and impact of several design parameters on the output characteristics are analyzed. In order to find the optimum style parameters, a multiobjective optimization drawback considering potency, power factor, and braking force due to the top impact is outlined. This downside is optimized with two algorithms, interior point and genetic algorithms, and results are compared. Finally, the validity of the obtained solution is verified employing a 2-D and 3-D time-stepping finite-component technique.
