Abstract

In this paper, four different structures are proposed to optimize electromagnetic thrust for the primary and secondary pole linear induction motors. Firstly, the two-dimensional topology structure of the motor is established, and the correlation equation of electromagnetic thrust is established. Secondly, the electromagnetic thrust optimization of the primary structure of the motor is carried out by the chamfer method and trapezoidal structure method. Then, the secondary structure of the motor is slotted and mixed with different conductivity materials to optimize the electromagnetic thrust. At the same time, a motor model with high permeability under ideal conditions is proposed from the angle of relative permeability of secondary aluminum plate. Finally, the four optimized structures were simulated, and the changes of electromagnetic thrust, air gap density, and back electromotive force were analyzed. The simulation results fully verify the effectiveness of the four optimization structures proposed in this paper.
