Abstract: This paper set up a linear induction motor model with ladder slits based on Maxwell 2D,and analysed the efficiency,propulsion force,normal force and magnetic field distribution.Compared to traditional motor with solid secondary conducting plate,by improving the width and interval of slits,this structure may increase efficiency and propulsion force,and improve the performance of linear induction motor.
