Analytical Modeling of Surface-Mounted and Consequent-Pole Linear Vernier Hybrid Machines

This paper presents an analytical method for modeling the no-load air gap flux density of a surface-mounted and consequent-pole linear Vernier hybrid machine (LVHM). The approach is based on simple magneto-motive force (MMF) permeance functions to account doubly-slotted LVHM. These models are used determine linkage, induced electromotive (EMF) average thrust each machine. accuracy two validated by comparison with 2D finite element (FEM) solutions. Based models, it found that working harmonics both LVHMs essentially same. However, magnitudes these in LVHM invariably greater than those Further, using model, contribution individual harmonic can be shown clearly, explain why has improved performance despite only 50% permanent magnet (PM) material compared
