Abstract

Recently, the E-core linear synchronous motor has been introduced to the family of linear motors  capable of exerting both traction and attraction forces. Due to the complexity of the magnetic structure of such  core-shape, attention must be paid while evaluating the machine parameters. Thereby. more exact estimation of  the expected machine performance can be ensured.  
  This paper is concerned mainly with the proper evaluation of the parameters of the E-core linear  synchronous motor; taking into consideration the flux fringing effect. This effect is one of the most important  factors which influence the air-gap reluctance faced by both the transverse and tangitudinal fluxes. The  developed approach to simulate the flux fringing in the air-gap regions has been resulted in a simple way to get  the effective pole areas under the middle and outer limbs. Accordingly, the values of center air-gap permeance corresponding to different air-gap flux components (ᶲf , ᶲad , ᶲaq ) and  intern the machine parameters (Maf , Lf , Lad , Laq) can be exactly evaluated. This way, the machine performance, especially the traction  and attraction forces, can be properly and easily predicted at this  phase of motor design process.  
Experimental measurements are carried out on a simple static model  to verify the proposed approach. The comparison between the theoretical  results. considering effect of magnetic flux fringing at pole edges,  and experi mental results on a static prototype motor shows that they  are in a good agreement.
