Abstract :
For a simple Maglev mover, the magnetic levitated, propelled and guided mover using the “magnet wheels” is discussed. The “magnet wheel” generates both the induction repulsive type magnetic lift force and the thrust by rotating permanent magnets mechanically over the conducting plate. The “partial overlap type magnet wheel” is used in the paper, in which the thrust is produced from the drag torque by setting the rotator near the edge of the conducting plate. The Maglev device using the four magnet wheels can levitate stably without vibration, pitching and rolling, and the damping always exists for any condition at standstill. The configuration with inclination magnet wheels at both sides makes the Maglev mover with guidance
