New transverse linear switched reluctance motor design and analysis for transit uses

Transverse linear switched reluctance motors (TLSRMs) are generally challenged by high-force ripples that contribute to a lower average propulsion force. This undermines the overall efficiency of the TLSRM in various industries. This paper presents structural modifications to improve the force performance of a TLSRM for transit applications. In this new design, a split-teeth stator design was proposed to virtually increase the number of stator teeth without increasing the number of translator teeth. The proposed TLSRM contains a movable translator with 16 poles for direct transmission with no gear mechanism. A hybrid TLSRM design method is presented, modifying the conventional design method to accommodate these structural modifications. A specific power output equation for the proposed motor was derived by correlating the force, power, and physical dimensions. The proposed motor was designed and analyzed using the FEM software to ensure the accuracy of the design.
