A novel linear-rotary permanent magnet actuator (LRPMA) is proposed in this paper, in which ferromagnetic poles and PM poles are mounted on the mover surface. A 3D analytical model without considering the stator slotting effect is presented for calculating no-load air-gap magnetic field, which transfers the tubular mover of the proposed LRPMA into a planar one. A permeance model is then built to consider the stator slotting effect in the circumferential and axial directions. The equations of cogging force and cogging torque are derived by the Maxwell stress tensor method and 3D finite element method (FEM). The analytical results of cogging force and cogging torque are consistent with those by 3D FEM.
