Abstract: In order to study the influence of the unique edge effect and normal force of single-sided linear induction motor, the effect of slip frequency on electromagnetic force and normal force output was analyzed based on constant current and constant slip frequency control to achieve optimal slip control. Considering the T-type equivalent circuit of single-sided linear induction motor and the end effect, the numerical relationship between electromagnetic force, normal force and slip frequency was calculated and derived. Combined with computer simulation, the characteristics of electromagnetic force and normal force output under conditions of different speed and different electromagnetic air gaps were studied, and the best slip frequency was sought to achieve optimal loss control of single-sided linear induction motor. The single-sided linear induction motor has been successfully applied to domestic Maglev Test lines.

Key words: single-sided linear induction motor, edge effect, slip frequency, normal force
