The characteristics of wound-secondary type of linear induction motor (LIM) with ground primary winding for light transit are studied. The simple two-dimensional electromagnetic analysis is used to study the characteristics. For a tentative specification, the optimum design parameters are discussed. From the viewpoints of the ratio of normal force to thrust, which is important for the suspension of vehicle, the pole pitch of about 0.2m will be best. For the rated thrust of 5 kN, the needed length of on-board secondary is about 2.7 m for the air gap flux density of 0.35 T. In this model, the efficiency decreases by about 8 % and 20 % respectively at the primary feeding length of 1.5 times and 2.0 times as long as the secondary, when the loss in the secondary member is neglected.
