Abstract Based on the linear traction system of urban rail transit, the linear induction motor (LIM) and the linear flux-switching permanent magnet (LFSPM) motor with toothed secondary have been compared comprehensively. Research results show that LFSPM motor with toothed secondary has the advantages of high thrust density, high efficiency and high power factor. However, the secondary volume and cost will be high when the toothed secondary used in long-distance drive systems such as rail transit. To reduce the cost of secondary, the topology of a new LFSPM motor with segmented secondary is proposed firstly, in which the secondary only consists of segmented magnetic blocks without yoke. Hence, this motor has some merits such as small size and low cost. Harmonic analysis of the air gap magnetic field of the motor is carried out and the mechanism of thrust generation is deduced Then, the two-dimensional finite element simulation model of the motor is established under the actual size and operating conditions of the Metro driven by linear motor and some key parameters are optimized. Finally, based on the optimal structure, the system cost and energy consumption of the proposed motor and LIM are compared and analyzed combined with Guangzhou Metro Line 4, which lays a theoretical foundation and design reference for the practical application of this kind of motor in the linear traction system of rail transit.

Key words： Linear motor flux-switching permanent magnet (FSPM) motor rail transit finite element analysis (FEA)
