Abstract

In this work, an analytical model is developed for the modulated flux density in the surface-mounted PM Vernier machines. The model is valid for on-load and no-load conditions. In the modeling process some conformal transformations, including a SchwarzChristoffel and a few bilinear transformations, as well the Laplace’ solution are applied to obtain the air gap flux density of the PMs and the armature reaction. The limitation of existing conformal transformation-based methods in the modeling of the modulated fields is discussed. To remove these limitations, the concept of the equivalent magnetization current and the uniqueness theorem are adopted. In the modeling process, the machine cogging torque and the electromagnetic torque are obtained analytically. Finally, the obtained results are compared with the results of finite element analysis and the results of the complex permeance model.
