永磁游标电机具有高转矩密度和低速转矩脉动小的明显优点。由于这些优点，它们被广泛的研究和提出用于风力发电[2]和波浪能转换[3]。为了提高PMVM的转矩密度，提出了一种新的双定子游标拓扑[4]，与传统的游标机相比，[4]具有更高的转矩密度和效率。然而，PMVM通常具有高永磁极对，这增加了机器的成本。为简单起见，本文将最近提出的机器称为现有机器。为了进一步提高转矩密度，降低现有电机的成本，本文提出了一种双定子顺极游标电机。结果表明，与现有电机相比，所提出的电机提供了更高的扭矩密度。此外，由于磁体体积减少，机器的成本也很低。
Permanent magnet vernier machines (PMVMs) have some distinct advantages of high torque density and low torque ripple at low speed [1]. Due to these advantages, they have been extensively researched and proposed for wind power generation [2] and wave energy conversion [3]. To increase the torque density of a PMVM, a novel dual stator vernier topology was presented recently [4], which possessed higher torque density and higher efficiency compared to a conventional vernier machine. However, PMVM generally have high permanent magnet (PM) pole pairs, which increases the cost of the machine. For simplicity, the recently presented machine will be termed as existing machine in this paper. In this paper, in order to further increase the torque density and decrease the cost of the existing machine, a dual stator consequent pole vernier machine has been proposed. The results show that the proposed machine provides a higher torque density compared to the existing machine. Moreover, the cost of the machine is also low since magnet volume has been decreased.
