Permanent magnet (PM) linear machines have been utilized in various applications due to their high force density, high efficiency and simple structure. In this study, the electromagnetic performances of three PM tubular machines, i.e. partitioned stator surface mounted permanent magnet (PSSPM), partitioned stator interior permanent magnet (PS-IPM) and switched flux permanent magnet (SFPM) tubular machines, are compared in terms of open circuit, on load electromagnetic performances and losses. It is found that both partitioned stator machines exhibit better magnet utilization compared to SFPM machine. Moreover, PS-IPM machine shows the highest thrust force capability among the other machines. On the other hand, the lowest thrust force ripple can be obtained by PS-SPM tubular machine. Furthermore, the lowest magnet eddy current loss is delivered by PS-IPM. In contrast, SFPM has the highest magnet eddy current.
