Abstract :
The characteristics of magnet wheels for magnetic levitation and linear drive applications are investigated by using a three-dimensional computer simulation. Magnet wheels levitate by revolving permanent magnets over a conducting plate, in which eddy currents are induced. Thrust is also produced by making the torque unbalanced. This paper deals with “partial overlap type” magnet wheels, producing a lift force and thrust. Magnetic flux density and eddy currents are examined for both 3-pole and 2-pole structures
