Design and Analysis of a Permanent Magnet Vernier Machine with Non-Uniform Tooth Distribution

To improve the torque performance of the permanent magnet vernier machine in the direct-drive system for Unmanned Aerial Vehicle (UAV), this paper proposes the topology of non-uniform tooth distribution. This distribution, considering the additional flux harmonics, aims to contribute to torque impro...
