Abstract A linear induction maglev motor (LIMM) with high temperature superconductor (HTS) traveling magnetic electromagnetic Halbach array (TMEHA) is proposed. The motor creates traveling magnetic field by 3-phase alternating current in primary electromagnetic Halbach array above a conductive guideway, the eddy current are induced in the guideway that can simultaneously create suspension and propulsion forces. The relations of HTS TMEHA parameter and performance of LIMM are calculated using an analytical method based on magnetic vector potential equation and boundary conditions. Then, the expression of the motor’s flux density distribution is derived. Finally, a small prototype with copper primary windings is manufactured to validate the analytical results.

Key words： Traveling magnetic electromagnetic Halbach array high temperature superconductor linear motor maglev
