<p>This paper introduces a novel dual-permanent magnet linear vernier machine (DPMLVM), which can achieve higher thrust density than the conventional permanent magnet linear vernier machine (CPMLVM). It features permanent magnets (PMs) placed in both the primary and secondary slots, forming a double consequent-pole structure. The toroidal-windings are easily embedded into the slots, while the distributed arrangement enhances the gear ratio. The working principle of the proposed DPMLVM is analyzed by bidirectional flux modulation. According to the magnitude and phase angle of the normal and tangential air-gap flux density harmonics under rated load, the thrust contribution of each working harmonic is quantitatively assessed by the Maxwell stress tensor (MST) method. The result shows that the proposed DPMLVM exhibits high thrust density, because its main thrust contribution comes from the working harmonics which correspond to the primary and secondary PM pole pair numbers (PPNs). The no-load back electromotive force (EMF) and inductance of the proposed DPMLVM with different slot-pole combinations are compared with CPMLVM. In addition, auxiliary poles are used to reduce the detent force and have a good effect on the thrust ripple for the proposed DPMLVM.</p>
