Abstract This paper proposed a transverse flux permanent magnet linear machine (PMLM) with the class distribution of the stator core group arrangement in the axial direction, due to the problem of larger thrust force ripple in transverse flux PMLM, which has some merits higher force density and better controllable characteristic etc. Firstly, the structure and operating principle of transverse flux PMLM was presented. Secondly, the influence of the class distribution of the stator core group arrangement on the motor performance is analyzed in detail. Special attention was paid to the back-EMF, cogging force and electromagnetic force etc. The paper investigated the influence of different arrangements in transverse flux PMLM, including theoretical analysis and numerical calculation. The results show that the thrust ripple can be decreased by the class distribution of the stator core group arrangement in transverse flux PMLM.
