Based on the one-dimensional field theory for linear induction motor (LIM), the analytical model of two adjacent series motors was built, then the relationships between spacing and traction, current, voltage, etc., were derived. The theoretical calculation results were directly verified by finite element simulation and indirectly verified by experiments. Eventually, the selection method for LIM spacing in medium-low speed maglev was proposed. The results show that the spacing affects the backward travelling wave of LIM1 (the first LIM) and the forward travelling wave of LIM2 (the second LIM), thus affects the traction of the motors; the variation range of LIM2 traction influenced by spacing can be as great as 1kN; a reasonable spacing can effectively improve the traction. The selection method of the spacing can provide technical guidance for the design of the medium-low speed maglev, and effectively improve the traction performance of the vehicles.
