  • In order to gain a greater starting thrust and higher running acceleration in evacuated tube HTS (high temperature superconductor) side-suspended maglev vehicle, and improve running stability at high speeds, a 2D simulation model for linear motor was established by studying the driving system of evacuated-tube HTS side-suspended maglev. The characteristics of the starting-thrust and normal force of the motor with different secondary plates were studied by finite element simulation and experiments. The results show that the secondary plates of different materials and thicknesses have significantly effects on the operation of maglev vehicle. When a 2 mm-thick commercial-purity aluminum plate was used as the motor secondary, the maglev vehicle could achieve higher starting thrust and accelerating performance with a high synchronous-speed. Meanwhile, low density of aluminum plate reduces the total weight of the maglev vehicle and it provides a levitation force in the hanging direction, which increases the running stability of the maglev vehicle.
