According to the actual ejection index requirements,the magnetic field characteristics and inductance characteristics of the variable pole distance double-sided linear induction motor were analyzed.In the analysis of the linear induction motor with continuous variation of the pole distance,the variable pole distance mode was extended to the form of the variable phase width.By analyzing the air gap magnetic field of the variable bipolar long primary bilateral linear induction motor,the magnetic induction intensity expression of the region where the arbitrary position is located was obtained.The effect of the variation of the pole pitch on the magnetic induction of the motor was simulated.The self-inductance and mutual inductance of the winding of the variable-pole linear induction motor were calculated,and the influence of the variation of the pole distance on the self-inductance parameters and the mutual inductance parameters was simulated.
