A new type of actuator with both magnetic levitation and linear drive is proposed. The actuator is called "magnet wheel", which has rotating magnetic field obtained by revolving permanent magnets with high coercivity mechanically. The induction repulsive type magnetic lift force with self-stabilization can be obtained by linking the rotating flux to a conducting plate . The induced simultaneously drug torque which causes power loss is made good use to get the thrust by the two proposed ways which are called "tilt type" and "partial overlap type", respectively. In the "tilt type" the magnet wheel is tilted against the surface of conducting plate. In the "partial overlap type" the magnet wheel operates near over the edge of conducting plate.<br>In this paper, first, the fundamentals of the structure of proposed magnet wheels are described. The basic characteristics at parallel to the conductor are shown by using a numerical three-dimensional electromagnetic analysis and measured results. The generation of both lift force and thrust in "tilt type" and "partial overlap type" magnet wheel are proved by experiments respectively.
