This paper presents a nonlinear adaptive magnetic equivalent circuit (MEC) of a coaxial magnetic gear (MG). High speed (HS) and low speed (LS) rotors are equipped with surface mounted PMs. The stationary ring (SR) located between the rotors is constituted by magnetic iron pieces which create the flux modulation. Using the MEC, the magnetic flux density is calculated in the different parts of the MG, as well as the stall torque. In order to evaluate the reliability of the proposed model, the results are compared to 2–D finite-element analysis (FEA).
