Abstract
Axial flux electrodynamic maglev motor (AFEMM), in which the 3-D finite-element method is time-consuming and the analytical model has insufficient accuracy, is presented in this article. Based on the magnetic field reconstruction method (FRM) and the second-order vector potential (SOVP), a 3-D calculation model of the motor, in which the expression of magnetic field in the air gap, the lift force, and torque was derived, was proposed and verified by a 3-D transient finite-element model. Finally, a small-scale prototype is manufactured, and experiments are carried out to verify the predicted results.
