Abstract

To avoid the problem of crowded primary and rising temperature of permanent magnet (PM), the design of partitioned primary hybrid excited linear flux switching machine (PP-HLFSM) positions the armature, and field excitation coil winding on separate part of the mover. This article examines the performance analysis of different structures of unaligned structure of PP-HLFSM and compared the proposed designs by reducing the usage of PM to half in terms of volume from 25,920 mm³ to 12,960 mm³, for both concentrated and toroidal winding structure leading toward cost effectiveness. This article scales down the cost of proposed designs for elevator long stroke application. Based on finite element analysis (FEA) and boundary element analysis, the electromagnetic performance of the machine is studied in detail. Single variable optimization is implemented to optimize both the proposed structures. Analysis includes flux linkages, flux strengthening, average force characteristics, force–velocity and power–velocity curves, copper losses, iron losses, efficiency, thrust force density and power density, and demagnetization analysis. Comparison of conventional structure with proposed designs are made in terms of flux, thrust force, losses, efficiency, power density, demagnetization of PMs, and thermal analysis, along with 3D FEA analysis. Finally, the proposed structures are analytically validated.
