For the secondary PM type, the PMs have a disadvantage of heat dissipation due to the presence of induced eddy current. [...]the PMs are prone to irreversible demagnetization at a high ambient temperature. According to different mounting positions of PM on the primary iron core, the topologies of the primary PM tubular linear machine can be divided into: flux switching tubular linear machine (FSTLM), primary PM tubular vernier linear machine (PPMTVLM) and flux reversal tubular linear machine (FRTLM). [...]the arrangement of single N pole type PMs will cause leakage between the adjacent primary of the unit machines, and reduce the utilization ratio of PMs. [...]the arrangement PMs dual N poles type is adopted in this paper, and the magnetic circuit between the adjacent primary of the unit machines is independent of each other. [...]for the three-phase 4-poles 12-slots primary PM consequent-pole TTFFRLM, the optimal topology has the following characteristics, the axial direction distribution of the PMs is the alternating distribution of single N pole type, the secondary is suitable for the continuous ladder structure, and the machine can be simplified as a unit machine for analysis.
