Abstract
A series of design curves for airgap permeance of vernier-type, doubly-slotted magnetic structures is presented in the paper. Permeance data are obtained from numerical field solutions. Reducing the number of governing geometric parameters makes it possible to express the airgap permeance in as convenient a manner as in equal-pitch-type structures. By using the Fourier expansion method, and these design curves, the airgap permeance per stator pole can be easily determined at any specified tooth misaligned position of a vernier motor.
