Abstract：A new kind of coreless linear induction maglev motor (CLIMM), which can be used in ultra-high speed maglev, is studied in this paper. The motor is an electro-dynamic system that can simultaneously create suspension and propulsion forces. The basic structure and principle of the proposed motor is firstly described. Then, an integral approach is proposed for modeling the vector magnetic potential of the primary winding. Taking the vector magnetic potential as the variable, a 2D analytic model of the CLIMM is proposed. Consequently, the magnetic field in the air gap, the lift force, the thrust force and the efficiency are calculated. Finite element analysis results verify the analytical prediction. Finally, the CLIMM with copper coil is designed and established to verify the analytical model.
