An electromagnetic suspension and guide system for a magnetically suspended vehicle comprises an armature rail of three-legged shape in cross section fixedly mounted on a rail support laid on the ground, and an electromagnet core of three-legged shape in cross section fixedly mounted on a magnetically suspended vehicle and disposed so that the three legs thereof are in an opposing relationship to the three legs of the armature rail with a gap therebetween, respectively. The three-legged electromagnet core has a different width from that of the three-legged armature rail, and the two side legs of the core are provided with windings wound thereon, respectively. The suspending and guiding operations of the vehicle are controlled by controlling the energizing currents supplied to the electromagnet. An electrical control circuit for producing such energizing currents includes a detector for determining the vertical and lateral positions of the electromagnet core relative to the armature rail, an amplifier connected to the detector, and a current controller responsive to the output signals from the amplifier for producing the energizing currents. |
