دانلود A novel performance study for linear induction motors considering end effects

Abstract

We  present  an  analysis  of  the  single-sided  linear induction motor with a solid-steel reaction plate. By solving for the two-dimensional field distribution in the air gap and in the secondary, the mutual reactance and secondary impedance are derived account for the longitudinal end effect factor. Meanwhile, other electromagnetic effects, such as  skin  effects,  the  thickness  of  the  secondary  plate  and  transverse  edge  effects  are  taken  into  account.  Traditional methods for solving the performance by using the electromagnetic  fields  are  very  difficult  to  achieve.  So  we propose  an  easier  method  to  calculate  the  performance  of the  single-sided  linear  induction  motor.  Simulation  results produced by this proposed analytical technique have a good agreement with the traditional results under constant-current  conditions.  The  analysis  is  valid  over  a  wide  range of operating conditions, and is useful for design studies.
