[Objective] The secondary segmented flux-switching permanent magnet linear motor (Sseg-FSPMLM)

which combines high efficiency with low cost

is well-suited for traction systems in urban rail transit. This paper investigates the applicability of the Sseg-FSPMLM under the condition of compatibility with existing traction and inverter feedback topologies

with the aim of evaluating its potential for practical engineering applications. [Methods] Firstly

using Guangzhou Metro Line 4 as a case study

a comparative analysis of the linear induction motor (LIM) and the Sseg-FSPMLM was conducted

focusing on motor efficiency and operational costs. Subsequently

without modifying the existing traction power supply system or inverter regeneration topology

an integrated simulation model was developed. This model incorporated the urban rail traction load

the regenerative energy storage device

and the grid interface. Finally

based on key parameter designs

the performance of the Sseg-FSPMLM-based inverter regeneration system was tested and evaluated. [Results] Under equivalent thrust requirements

the Sseg-FSPMLM achieved a 20% improvement in efficiency compared to the LIM

along with a 34% reduction in material costs. Simulations performed using the developed inverter regeneration model demonstrated a total recovered energy of 9.23×105 J

accounted for 43.74% of the kinetic energy present before braking. [Conclusion] When the Sseg-FSPMLM is deployed as a traction motor in existing systems

no structural modification to the inverter regeneration topology is required. By solely re-optimizing the electrical parameters

the dynamic performance and stability of the regenerative braking energy feedback system can be effectively ensured. This verifies the feasibility of directly integrating the Sseg-FSPMLM into current rail transit infrastructure.
