Structural Optimization of Linear Induction Motor for Reducing End Effect

Abstract

This article concentrates on the optimized design about the structures of the stator in linear induction motors, with the aim of reducing end effects. When the linear induction motor is operating at high speed, the induced eddy current generated by the secondary conductive plate will distort the air gap magnetic field and increase the loss of the linear induction motor. Established in the short primary two-sided linear induction motor, three types of stator optimization schemes are compared and analyzed, and the forward extension triangle slot is taken as the final optimization scheme. The results indicate that adopting the stator slot scheme of forward, expanding triangle can reduce the air gap magnetic field distortion and increase the electromagnetic force of the linear induction motor. Ultimately, the finite element software is used to optimize the parameters to further improve and improve the stator structure of the linear induction motor. The work of this paper is chiefly to provide a new design idea for reducing the end effect of linear induction motors.
