Abstract

The Axial-Flux Solid Aluminum Rotor Induction Motor (AFAIM), which is Electro-dynamic System [1-2], is presented in this paper. The system creates electromagnetic field by 3-phase alternating current in primary winds, induct eddy field in secondary and create lift and thrust force. This paper establishes a 2-D sub-loop electro-magnetic model, studies the dynamic characteristic of the maglev, gets lift and thrust force analytical solution. Finally, the paper analyses the model using FEM software and gets the distribution of magnetic field. The conclusion provides important method and theory basis for the characteristic and magnetic-field of axial-flux solid rotor induction motor.
