The Vernier permanent magnet machine is a high-torque, low-speed system suitable for direct-drive applications such as in-wheel electrical machines and wind generation turbines. In this paper, specific critical parameters of the electrical machine for auxiliary tooth and slot are investigated in different conditions. It should be noted that all the models are fully optimized and compared under the same condition by FEA analysis. The results illustrate that the stator with α β θ is the best choice for stator split pole. Also, the concentrated winding is wound around the main stator tooth and the magnets mounted on the rotor surface. Besides, all essential characteristics for an electric machine such as torque, cogging torque, power factor, and efficiency are investigated. Furthermore, many basic formulas for designing a Vernier machine are proposed. This comparison helps designers choose the best combination among α, β, and θ in the split-pole structures. There is a nomenclature to organize this manuscript for the reader. It should be noted that all the figures are baked by ANSYS Electronics Maxwell version 19.0. Moreover, all of them are modified by Origin software to show with high quality.

“…The method to identify the optimal flux modulation pole number in PMVMs for maximising the torque is proposed [8]. The stator topologies of PMVMs with concentrated winding are investigated to generate the maximum torque [9]. To alleviate flux leakage and reduce the costly consumption of PM, the consequent‐pole rotors are proposed, such as the surface‐embedded magnet, V‐shape magnet, and U‐shape magnet [10–12].…”

In this study, the permanent magnet vernier motors (PMVMs) with different external rotor topologies are investigated and compared to obtain the optimal topology, which can reduce the vibroacoustic noise and keep the excellent output performance. Firstly, the unipolar and bipolar PMVM motors with V‐shape magnets are designed based on the torque and cost of the consequent‐pole PMVM (CPMVM), which have the reduced unbalanced magnetic force (UMF). Then to evaluate the performances of PMVMs comprehensively, the characteristics including flux density, back‐electromotive force, torque, the electromagnetic force and acoustic noise etc., are quantitatively investigated and compared by the finite element analysis (FEA). Finally, the modal parameters and acoustics noise spectrum of CPMVM are tested and compared with the noise FEA results, which verify the V‐shape magnet PMVMs can reduce the UMF and low‐frequency noise level by maintaining the output performance.
