CHARACTERISTICS OF EDS (ELECTRO-DYNAMIC SUSPENSION) MAGLEV HAVING LEVITATION COILS ON THE SIDE WALL ON THE GUIDEWAY

EDS maglev system aiming at high speed transport is required to reduce magnetic drag in its levitation system. In the paper the levitation force and the stiffnesses characteristics of a method which arranges ground coil for levitation on the side wall to use the principle of null flux are analyzed and a numerical example is shown. According to the numerical example, maximum levitation force is about four times the rated value, and the drag ratio is higher than the value in the usual feasibility study. The lateral and yawning stiffnesses are positive values. The other stiffnesses are large values.
