Abstract

Design and analysis of a magnetic gear (MG) needs to pricise calculation of flux density distribution along the MG. However applying the finite element methode is relatively accurate, it takes a long time in the preliminary design process in order to study the effective parameters. One of the new structures of MGs is consequent-pole mahgnetic gear (CPM) kind that saves the permanent magnet (PM). In this paper, the 2-dimensional (2D) modeling of a CPM using magnetic equivalent circuit (MEC) method is presented which determines the distribution of magnetic fields, fluxes, and torques of inner and outer rotors. To evaluate the performance of the proposed model, a CPM is analysed with two pole PM arc coefiecinet and flux density is extracted in different parts of CMG as well as its radial and tangential  component of tourqu. Furthermore, to confirm the proposed model results, the finite element analysis was performed by Ansoft / Maxwell software that verifies the MEC results.
