Abstract :
Lift force, thrust and lateral force characteristics of “partial overlap type magnet wheel” are presented, where “magnet wheel” is a proposed electromagnetic device for an induction repulsive type Maglev vehicle constructed with revolving permanent magnets and conducting plate, and “partial overlap type” is one type of magnet wheel. Smaller resistivity of the conducting plate induces larger lift force and lateral force except thrust. The 2-pole arrangement has maximum thrust at larger overlap than 4-pole. The wall of the conducting plate gives larger lateral force without adverse influence on lift force and thrust
